The robust design means that they can also be used in rough conditions. ifferent types of flanges, liners and float materials satisfy the requirements of the pharmaceutical and chemical industries.

1 Fig. variable area flow meter pplication The V 5 variable area flowmeters with a standard length of 5 mm (9.84 inch) and a completely metal design can be used to measure many different types of liquids and gases passing through closed piping. The robust design means that they can also be used in rough conditions. ifferent types of flanges, liners and float materials satisfy the requirements of the pharmaceutical and chemical industries. The measured value is displayed directly on the scale, and output via a switch contact or as a current output. The main applications for the V 5 can be found in the following fields: Chemical industry Water Power generation and distribution. Special features Standard design available at short notice Robust all-metal fitting with impact-resistant housing cover Can also be used for corrosive and flammable media Use possible at high pressures and temperatures Product and percentage scales Can be optionally fitted with heating and cooling sheaths Contamination-insensitive guiding of float. esign and mode of operation Fig. Flow tube/scale angle Note of application The operator of these measuring instruments is responsible for suitability, proper use and corrosion resistance of the used materials with regard to the measuring material. It must be ensured that the materials selected for the flowmeter parts in contact with the medium are suitable for the used process media. No external loads may act on the meter. Provide a touch guard for surface temperatures of > 7 C. This touch guard must be designed in a way that the max. allowable ambient temperature on the unit is not exceeded. The flowmeter may only be used within the pressure and voltage limits specified on the identification plate. Before replacing the measuring tubes, check that the unit is free of hazardous media and pressures. The measuring instruments are primarily designed for static loads.

III III III The V 5 operates like the other units in the V range according to the variable-area flow tube principle: the flowing medium lifts the conical float in the flow tube. The annular gap is then increased until equilibrium exists between the buoyant force of the medium and the force due to the weight of the float. The height of the float is directly proportional to the flow quantity. The movement of the float is transmitted by a magnet to a slave magnet in the display unit outside the flow tube. The contacts or the electric remote sensor are controlled by a contact lug or a cam which is mounted on the pointer shaft.

5 Installation and operating instructions The main information for installation and startup is listed below. Further information can be obtained from VI/V 5, sheet, installation recommendations for variable area meters. Installation instructions The variable area meter is delivered protected in a PVC sleeve, and is ready for operation. It has been checked for correct functioning prior to delivery. Before installing, check that the float moves freely: the float must slide smoothly in the flow tube without sticking or tilting. The pointer must smoothly follow the movement of the float. In the rest position (zero flow), the pointer must point to the marked reference point (first scale line). In the end position of the float, the pointer must be positioned above the full-scale value. The variable area meter must be fitted into the piping vertically and without tension. Magnetic fields from other equipment may influence the result. If several variable area meters are installed next to one another, the following minimum distances must be observed between the main axes of the variable area meters: N 5 to 5 (½ to inch): 5 mm (9.84 inch) N 8 to ( to 4 inch): 4 mm (5.74 inch). The flange screws of the -lined fittings must only be tightened with the following maximum torques: N 5 to 5 (½ to inch): 4 Nm N 5 ( inch): 5 Nm N 8 ( inch): 5 Nm N (4 inch): 4 Nm Interference-free inlet and outlet pipe sections are not usually required. However, additional measures (inlet pipe sections, flow stabilizers) may be meaningful to retain the measuring accuracy in the case of highly asymmetric flow profiles. To prevent pulsations resulting from compression when measuring gases, a throttle should be positioned directly downstream of the variable area meter. To avoid faulty measurements, the arrangement should be selected such that the pressure in the variable area meter corresponds to the reference pressure for the calibration. The flowmeter may only be used within the pressure and voltage limits specified on the identification plate. Startup. When starting up new plants, material residues (e.g. welding spatter) are carried over in the medium and could be deposited on the variable area meter. In such cases it is recommendable to clean the variable area meter after a short period of operation.. The float must not be exposed to sudden pressures. It is therefore recommendable to start with a closed valve which is then slowly regulated to the operating pressure. Liquids should be vented carefully to prevent pressure surges resulting from gas bubbles.. The variable area meter outputs values in all scale ranges according to its accuracy class. ach time a flow is started, permit the variable area meter to settle. When measuring in the lowest range, initially set a higher flow for a short time. Maintenance and repair epending on the medium, contamination, abrasion or chemical reactions may attack the orifice and the float, thus influencing the accuracy of the measurement. In such cases it is recommendable to dismount the variable area meter and to clean it, including the float, with appropriate agents. The orifice and float must not be damaged mechanically or by aggressive cleaning agents. If erosion is noticed on the orifice or float, recalibration or replacement is necessary. Following all maintenance and cleaning operations, carry out a function test of the variable area meter before using it again.
