4 SITRNS P Remote seals for transmitters and pressure gauges SITRNS P 7MF9.. Introduction pplication The remote seals 7MF9.. can be fitted to SITRNS P transmitters for pressure (7MF00, 7MF0, 7MF020 and 7MF02), absolute pressure (7MF20, 7MF22, 7MF2) and differential pressure and flow (7MF20 and 7MF2). esign and mode of operation remote seal system consists of a transmitter, one or two remote seals, an appropriate transmission liquid, and a connection between the transmitter and remote seal (direct mounting or capillary). The volume in contact with the measured medium is terminated by an elastic diaphragm. The volume between this diaphragm and the pressure gauge (transmitter or manometer) is completely filled with a transmission liquid. If a pressure is now applied to the remote seal, this is transmitted via the elastic diaphragm and the filling liquid to the pressure gauge. In many cases, a capillary is located between the remote seal and the pressure gauge in order e.g. to minimize temperature effects from the hot medium on the latter. However, the capillary line influences the response time and the temperature response of the complete remote seal system. When fitting remote seals to differential pressure transmitters, two capillaries of the same length must always be used. Fields of use Remote seal systems should be used if a separation between the measured medium and the measuring instrument is appropriate or essential for the following reasons: The temperature of the medium is outside the limits specified for the transmitter. The medium is corrosive and requires diaphragm materials in the transmitter which are not available. The medium is highly viscous or contains solids which would block the measuring chambers of the transmitter. The medium may freeze in the measuring chambers or pulse line. The medium is heterogeneous and fibrous. The medium tends towards polymerization or crystallization. The process requires quick-release remote seals, as necessary e.g. in the food industry for fast cleaning. The process requires cleaning of the measuring point, e.g. in a batch process. onstructional designs differentiation is made between diaphragm seals and clampon seals. With the diaphragm seals, the pressure is measured via a flat diaphragm which rests in a bed. With the clamp-on seals, the pressure is measured via a cylindrical diaphragm positioned in a pipe, and transmitted to the transmitter via the filling liquid. The clamp-on seal is a special design for flowing media. It consists of a cylindrical pipe in which a cylindrical diaphragm is embedded. Since it is completely integrated in the process pipe, no turbulences, dead volumes or other obstructions to the flow occur. The clamp-on seal can furthermore be cleaned by a pig. Fig. / iaphragm seal of sandwich design, and also with projecting diaphragm (tube) Fig. / iaphragm seal of flange design, and also with projecting diaphragm (tube) Fig. / Quick-release remote seal iaphragm seals The following types of diaphragm seals exist: Sandwich design, and sandwich design with projecting diaphragm (tube) to IN or NSI which are secured using a dummy flange (Fig. /). Flange design, and flange design with projecting diaphragm (tube) to IN or NSI which are secured using holes in the flange (Fig. /). Quick-release remote seals, e.g. to IN, SMS standard, IF standard, PV RJT standard, clamp connection, etc. (Fig. /). The quick-release remote seals are common designs in the food industry. Their design means that the measured medium cannot accumulate in dead volumes. The quick-release clamp present on the remote seal means that quick dismounting is possible for cleaning. The following types of quick-release remote seals exist: Miniature diaphragm seal with male thread for screwing into tapped holes (Fig. /6). Remote seals with customer-specific process connections.

5 SITRNS P Remote seals for transmitters and pressure gauges 7MF9.. Introduction lamp-on seals The following types of clamp-on seals exist: Quick-release clamp-on seals, e.g. to IN, SMS standard, IF standard, PV RJT standard, clamp connection etc. The quick-release facility enables the seal to be removed quickly for cleaning purposes (Fig. /7). lamp-on seals for positioning between IN or NSI flanges (Fig. /7). lamp-on seals with customer-specific process connections. Transmission response Temperature errors occur if the filling liquid in the remote seal and in the capillaries expands or contracts as a result of temperature effects. The temperature error depends on the diaphragm rigidity, the influence of the filling liquid, and the influence of the filling liquid under the process flanges or in the connection spigots on the transmitter. iaphragm rigidity The rigidity of the remote seal is of decisive importance. The larger the diaphragm diameter, the softer it is. In comparison to a smaller diaphragm, this means that it can respond far easier to temperature-based expansions of the filling liquid. The result is that small measuring ranges are only possible with large diaphragm diameters. In addition, the diaphragm thickness, its material, and any coatings which may be present must be considered. Filling liquid ll filling liquids expand or contract when the temperature varies. Temperature-independent errors can be minimized by selecting a suitable filling liquid, but it must also be ensured that the filling liquid is appropriate for the temperature limits and operating pressure, and is also physiologically harmless. Since the filling liquid is present under the remote seal diaphragm, in the capillaries and under the process flanges of the transmitter, the temperature error must be calculated separately for each combination. Response time The response time depends on the internal diameter of the capillaries, the viscosity of the filling liquid, the capillary tube length, and the pressure in the measuring system: Internal diameter: The response time decreases as the internal diameter increases, but the temperature error increases. Viscosity: The response time increases as the viscosity increases. apillary length: The capillary length has a proportional effect on the response time and the temperature error. Measuring system pressure: The response time decreases as the pressure in the measuring system increases. Recommendations The following should be observed to obtain an optimum combination of transmitter and remote seal: The remote seal diameter, and thus the effective diameter of the diaphragm, should be selected as large as possible in order to keep the temperature-dependence errors as low as possible. The capillaries should be selected as short as possible in order to keep the response time and the temperature-dependent errors as low as possible. Fig. /6 Miniature diaphragm seal with diaphragm flush with front Fig. /7 Quick-release clamp-on seal and for flange mounting filling liquid should be selected which has the lowest viscosity and the lowest coefficient of expansion, and which simultaneously fulfills the process requirements with respect to pressure/vacuum and temperature. The filling liquid must also be compatible with the process medium. When installing the equipment for low-pressure applications, the transmitter must always be located below the lowest spigot. It should also be noted that some of the filling liquids are very limited with respect to the permissible temperature of the medium for low-pressure applications. When operating permanently at a low pressure, the remote seal must be designed in the version resistant to low-pressure. Recommendations on the minimum span can be found in the tables on pages /9 and /60. Note The remote seals listed in this catalog are a selection of the most common designs. s a result of the large variety of process connections, it may nevertheless be the case that certain remote seals which are not listed in the catalog are still available. Other versions could be: Other process connections, standards septic or sterile connections Other dimensions Other nominal pressures Special diaphragm materials, including coatings Other sealing faces Other filling liquids Other capillary lengths Sheathing of capillaries with protective hose alibration at higher/lower temperatures etc. Please contact your Siemens Regional Office for more information. / Siemens FI

The listed values must be multiplied by the respective length of the capillary tube, or with transmitters for differential pressure and flow by the total length of both capillary tubes. The response times are independent of the set span within the range of the respective transmitter. The response times are of insignificant importance for spans above 0 bar. The response times of the transmitters have not been considered.

23 SITRNS P Remote seals for transmitters and pressure gauges Measuring setups SITRNS P Measuring setups Transmitter output The following pages show examples of typical measuring setups for use of SITRNS P transmitters with and without remote seals, such as: Setups for transmitters with connection of remote seals, with associated equations for calculation. Questionnaires hecking of combination between transmitter and remote seal Setups for transmitters without remote seals, with associated equations for calculation Questionnaires Influence of ambient temperature For hydrostatic level measurements Installation Remote seals of sandwich design are fitted between the connection flange of the measuring point and a dummy flange. Remote seals of flanged design are fitted directly on the connection flange of the measuring point. The respective pressure rating of the dummy flange or the flanged remote seal must be observed. The transmitter should always be installed below the connection flange, and below the lower connection flange in the case of differential pressure transmitters. When measuring at pressures above atmospheric, the transmitter can also be installed above the connection flange. When measuring at pressures below atmospheric, the transmitter must always be installed below the connection flange, and below the lower connection flange in the case of differential pressure transmitters. Offset of measuring range If there is a difference in height between the two connection flanges when measuring with two remote seals, an additional differential pressure results from the oil filling of the remote seal capillaries. This results in an offset of the actual measuring range and must be taken into account when adjusting the transmitter. n offset in the measuring range also occurs when combining a remote seal with a transmitter if the latter is not installed at the same height as the former. If the level, separation layer or density increase in closed vessels, the differential pressure and the output signal of the transmitter also increase. If an inverted relationship is desired between the differential pressure and the output signal, the startof-scale and full-scale values of the SITRNS P must be interchanged. With open vessels, an increasing pressure is usually assigned to an increasing level, separation layer or density. The capillaries between the remote seal and the transmitter should be kept as short as possible to obtain the good transmission response. Temperature differences between the individual capillaries or between the individual remote seals should be avoided. If the complete setup is exposed to temperature variations, errors result from the thermal expansion of the filling liquid in the capillaries, in the remote seals and in the connection units of the transmitters. Notes When measuring separation layers, ensure that the layer is positioned between the two spigots. lso ensure that the level in the vessel is always above the top spigot. When measuring density, make sure that the level of the medium remains constant. The level is usually above the top spigot. /76 Siemens FI

With one clearly-defined phase liquid, vapor or gas, no solid components it can be used within wide temperature and pressure ranges. Electric differential pressure transmitters (from page /2 onwards) are connected to the differential pressure devices. Errors due to fluctuations in the state of the medium pressure and temperature can be corrected by a measured-value computer (from page /9 onwards). esign Standard orifice plates or nozzles are used in the normal case. These are robust units. In order to measure the differential pressure, these have either annular chambers connected to the inside of the pipe via an annular gap or have single tappings. The latter design is preferably used for higher pressures. Since the measurements can be influenced by wall roughness and diameter tolerances in the case of pipes with smaller nominal diameters (N 0 to N 0), metering pipes are used for this range. These are primary differential pressure devices with inlet and outlet sections made of precision pipes. The pipe lengths correspond to IN Metering pipes can be flanged or welded into a pipeline. The flow coefficient must be determined by experiment to permit exact measurements with metering pipes of N 0 to N 0. The primary differential pressure devices are calculated according to IN EN ISO 67, 99 and the VI 200 and 20 guidelines. In special applications which cannot be covered by these standards, manufacturing is carried out following consultation with the customer. If the calculation is required when a primary device is ordered, the calculation sheet (see page /2) must be included with the required data: pipeline, mounting position, medium, measuring range etc. The diameter of the primary device opening is then calculated or, if no solution is possible with the supplied data, the value which deviates from the required nominal diameter and differential pressure as little as possible. If a calculation is not required, the diameter of the primary device opening must be specified when ordering. ertificates. and. to EN 0 20 (IN 0 09) available on request.

In the case of orifice plates with annular chambers, two rings support the replaceable orifice disk; in the case of orifice plates with single tappings, the orifice disk and the support rings are one unit. These one-part orifice plates are suitable for higher pressures. Shapes of the orifice disk aperture (Fig. /2) The primary differential pressure devices are manufactured according to IN EN ISO 67. ccording to this, the application range of the standard orifice disk aperture form is limited by the Reynolds number. The limits depend on the diameter ratio b = d/. (: internal diameter of pipe). In the case of Reynolds numbers from approx. 0 to 0, the orifice disk aperture form (quarter circle) can be used for slightly less accurate measurements. The profile radius r depends on the diameter ratio b and results from the calculation of the diameter of the orifice disk aperture d.

In the case of horizontal steam lines, straight sockets are arranged opposite each other or, if the pipe is close to a wall, bent sockets on one side (Fig. /2). In the case of vertical and inclined steam pipes, the lower socket is bent upwards so that the connection flanges and compensation vessels are also at the same height in this case (Fig. /26).

Venturi nozzles have a smaller remaining pressure loss than IS 92 nozzles and orifice plates (Fig. /2); the energy costs are lower. Venturi nozzles are more expensive, however, because their manufacture is more difficult, and the most economical solution must be considered in each case. The accuracies of orifice plates and IS 92 nozzles are identical. Orifice plates with orifice disk apertures of forms and as well as Venturi nozzles are less accurate.

If the cross-section is reduced at one point, the flow rate must increase at this point. ccording to ernoulli s energy equation, the energy content of a flowing medium is constant and is the total of the static (pressure) and kinetic (movement) energies. n increase in the flow rate therefore results in a reduction in the static pressure (Fig. /27). This pressure difference, the so-called differential pressure, is a measure of the flow. In general the equation applies: q = c p Where: q Mass or volume flow (q m, q v ) p ifferential pressure c Factor depending on the dimensions of the pipe, the type of restriction, the density of the flowing medium etc. This equation states that the differential pressure generated by the restriction is proportional to the square of the flow (Fig. /2). In order to measure the flow, a primary differential pressure device is fitted at the point of measurement. This restricts the pipe and has two connections for sampling the differential pressure. If the properties of the primary device and the medium are known such that the above equation can be evaluated, the differential pressure is a measure of the absolute flow. No comparison measurements are required; the flow measurement can be checked independent of the device manufacturer. q % p % Setting range for application point of square-rooted characteristic for SITRNS P differential pressure transmitter Fig. /2 Relationship between flow q and differential pressure p /0 Siemens FI

56 Permissible operating pressure The permissible operating pressure in a pipe is the highest pressure to which the pipe sections designed for a certain nominal pressure may be subjected. The magnitude of the permissible operating pressure for a pipe section designed for a specific nominal pressure depends on the permissible operating temperature and the material used. If the starting material envisaged in the dimensional standards is used, the permissible operating pressure is the same as the nominal pressure at a temperature of 20. t other temperatures, the dependence of the permissible operating pressure on the nominal pressure for individual materials or groups of materials can be obtained from the special standards. Pressure variations, possible increases in temperature, and additional mechanical stresses must be taken into account when determining the permissible operating pressure. It may then be advisable to select a higher nominal pressure stage.
