Variable Area Flow Meter

TM Trogflux

	The TM Trogflux variable area meters are used to measure the volume of transparent liquids and gases passing through closed piping. The variable area meters can also be used for flow monitoring if they are equipped with one or more switching contacts. Standard scales are available for liquids with a density of 1 kg/l (62.43 lb/cu.ft). The scales must be recalculated for all other media depending on the physical characteristics. Applications: Potable water preparation Plastering machines Cooling water measuring devices Measurement of gas injection General installation in plastic pipes Download: Variable Area Meter TM Trogflux Inquiry Sheet	variable area flow meter measurement of transparent liquids and gases optional equipment with one or more switching contacts low-cost plastic design simple assembly and handling short delivery times for standard versions polyamid (optionally polysulfone) flow tube with various float materials connections: G ¼"...

TM Tubux

	The TM Tubux variable area meters are used to measure the volume of transparent liquids and gases passing through closed piping. The variable area meters can also be used for flow monitoring if they are equipped with one or more switching contacts. Standard scales are available for liquids with a density of 1 kg/l (62.43 lb/cu.ft). The scales must be recalculated for all other media depending on the physical characteristics. The flow tube is also optionally available with a percentage or 2-mm (0.078 inch) scale. Applications: See Trogflux plus Resistance against chemical and higher temperatures With protected glass flow tube Accuracy class 1,6 Download: Variable Area Meter TM Tubux Inquiry Sheet	variable area flow meter measurement of transparent liquids and gases optional equipment with one or more switching contacts robust versions with various materials usable for high pressure short delivery times for standard versions glass flow tube with various float materials connections: G ¼"...

TM 250

	The TM 250 variable area meters with a standard length of 250 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. Different 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. Applications: Chemical industry Water Power generation and distribution Download: Variable Area Meter TM 250 Inquiry Sheet	variable area flow meter measurement of transparent and turbid liquids and gases applicable also for corrosive or flammable media measured data accessible through switch contact or current output robust all metal fitting with impact resisting housing cover Usable for high pressure and temperatures optional heating or cooling sheaths contamination insensitive guiding of float short delivery times for standard versions all-metal variable area meter with various float materials Connections: DN 15 to DN 100 (½" to 4") temperature of medium: -20 °C to +300 °C (-4 to +572 °F) optionally available with analog output or contacts

TM Unox

The TM Unox variable area meters are used to measure the volume of transparent liquids and gases passing through closed piping. The variable area meters can also be used for flow monitoring if they are equipped with one or more switching contacts. Standard scales are available for liquids with a density of 1 kg/l (62.43 lb/cu.ft). The scales must be recalculated for all other media depending on the physical characteristics.

F O delta p

	Primary differential pressure devices are standardized, mechanical flow sensors. Through constriction of the line diameter in the device, the flow creates a differential pressure, which is converted with the help of a differential pressure transmitter into a proportional current signal or flow value. The assignment of differential pressure to flow is created by means of an orifice plate calculation. Applications: Power stations, measurement of steam, condensate and water Petrochemical industry, measurement of water, steam and liquid and gas hydrocarbons Chemical industry, measurement of various liquid and gas media Download: Differential Pressure Device F O DELTA P Inquiry Sheet	nominal diameters DN 10 to DN 1000 (0.4" to 40") temperature of medium: -200 to +500 °C (-328 to +932 °F) for vapors, gases and liquids.
