3 Functional description The flowmeters in the FM3200 work according to the float principle. The position of the float in the conical meter tube is proportional to the flow. magnet in the float translates the height of the float as a measurement for the flow to the decouple-proof magnet follower system of the flowmeter. The flow rate value is indicated on a scale by a pointer mounted on a rotating shaft. 6 5 Fig. : Structure (example) Meter housing 2 Meter tube 3 Float with magnet 4 Indicator housing 5 Magnet follower system 6 Cable entry The devices are used for local indication of the current flow rate with integrated alarm signalling units as flow rate monitors or with differential pressure regulators. The devices are also available with an angular position transmitter with m output signal as an option G00744 Introduction and basics Installation conditions General The following points are to be considered during installation: The armored variable area flowmeter is installed vertically in piping. The measuring media must flow from bottom to top. Keep the device as far as possible from pipe vibrations. Fastening the piping is normally sufficient. Keep the device as far as possible from powerful magnetic fields. Magnetic fields that are required for operating reasons must not influence the measurement result. The piping should be the same size as the connection size of the flowmeter. Inlet and outlet sections are not required. Valves and pipe bends can be screwed on directly. void pulsating flows and sudden pressure surges. Use slow opening valves. If the flowmeter is installed in a pipeline where decommissioning is impossible or inexpedient, a bypass line should be provided. For gaseous measurement media, the flowmeter should be installed as close as possible to the pipe constrictions. The nominal diameter of the piping at the outlet of the flowmeter should be measured as small as possible. Shut-off and throttle valves should preferably be attached to the outlet of the flowmeter. For liquid measuring media, the nominal size of the piping should be dimensioned as large as possible (if economically viable). FM3200 DS/FM3200-EN Rev. D 3

The maximum permitted temperature of the heat tracing must not exceed the permitted measuring medium temperature. When using electrical heat tracing, attention must be paid to potential functional impairment by electromagnetic fields. Fig. 2: Installation of the flowmeter Shut-off valve in the inlet 2 Flowmeter 3 Shut-off valve in the outlet 4 Bypass line G0736 Operating conditions variable area flowmeter is specified for a defined set of operating conditions of the measuring medium. For liquids and gases, these are pressure and temperature-related properties (density and viscosity) under operating conditions. For gases, in particular, this means operating at a specific operating pressure and operating temperature. The specified accuracy of the device always refers to the operating conditions underlying the specification. Installation recommendations Refer to VDI / VDE Directive 353 sheet 3, Selection and Installation Recommendations for Variable rea Flowmeters. Pressure chambers and collecting tanks If piston pumps or compressors are used for the transport of the measuring media, a pulsating flow of the measurement media must be expected. In order to reduce the pulsating of the float, the installation of pressure chambers or collecting tanks in the piping before the flowmeter is recommended. Pressure loss The available operating pressure at the measuring point must be higher than the pressure loss listed for the flowmeter in the specifications. It is important to also consider the pressure loss downstream from the flowmeter due to losses in the piping and other fittings. For information on pressure loss, see chapter "Measuring range table" on page 0. Sensor insulation If the flowmeter needs to be insulated, only the meter tube must be included in the pipe insulation. The indicator housing must not be insulated. This prevents the temperature in the device from rising beyond permitted limits. 4 DS/FM3200-EN Rev. D FM3200

5 Prevention of compression oscillations when measuring gases With low flow amounts and low operating pressure, so-called compression oscillations of the float can occur. If the maximum upstream pressure listed in the specifications is not reached, the flowmeter can optionally be equipped with a mechanical float damper. Damping is available for the device types FM3225 and FM3255 with a process connection size > /4". To prevent self-generated compression oscillations, note the following information from VDI / VDE 353 Sheet 3: Select a flowmeter with the lowest possible pressure loss. Minimize the piping length between the flowmeter and the closest up or downstream throttling location. Restrict the usual measuring range from the usual 0 % to 25 %. When setting the flow rate value, always start assuming larger values. Increase the operating pressure and consider its effect on the flow rate values due to the change in gas density at the new operating conditions. Minimize non-throttled, free volumes upstream and downstream of the device. Solids content in the measuring medium Variable area flowmeters have only limited suitability for measuring media containing solids. Depending on the concentration, particle size and type of solid, increased mechanical abrasion may occur, especially at the critical measuring edge of the float. In addition, solidified deposits on the float can change its weight and shape. These effects can lead to erroneous measurement results, depending on the float type. In general, the use of appropriate filters is recommended in such applications. For the flow measurement of measuring media containing magnetic particles, we recommend the installation of a magnetic separator upstream of the variable area flowmeter. Pressure shocks Especially when measuring gases, it is possible that pressure or shock waves can occur when fast opening solenoid valves are employed and the piping cross-sections are not throttled, or if there are gas bubbles in liquids. s a result of the sudden expansion of the gas in the piping, the float is forcibly driven against the upper floatstop. Under certain conditions, this can lead to destruction of the device. The mechanical float damping is not suitable for the compensation of pressure shocks! FM3200 DS/FM3200-EN Rev. D 5

When using electrical heat tracing, attention must be paid to potential functional impairment by electromagnetic fields. The specifications of EN must be observed. Use with zone 0 in the meter tube. Ensure that the ambient conditions are suitable for devices in zone (e.g. through ensuring sufficient ventilation). The FM3250 / FM3255 models with angular position transmitters are not approved for use in potentially explosive atmospheres! Electrical connections B 2 4 Temperature data Maximum permissible ambient temperature T ambient : C ( F) Maximum permissible measuring medium temperature For the maximum measuring medium temperature, refer to the tables in chapter "Limit value tables" on page 8. The maximum permissible measuring medium temperature for dust explosion protection is derived from the possible surface temperature of the flowmeter. The higher value must be used.
