The GFT range of Turbine Flowmeters are suitable for the measurement of mainly dry gases ( inert and flammable ) and are designed to operate at line pressures down to 15 mbar
The GFT range of Turbine Flowmeters are suitable for the measurement of dry gases ( inert and flammable ) and are designed to operate at line pressures down to 15 mbar . They comprise of one cartridge assembly, fitted inside a stainless steel body ( locked with an internal circlip ) , which has a magnetic pick up fitted and come in a range of threaded , flanged or wafer ( designed for between flange installations ) styles . The Rotor ( fitted with low inertia , precision bearings ) is turned by the kinetic energy of the flowing gas at an angular velocity , which in the linear range of the Flowmeter is proportional to the mean axial velocity of the gas . The Rotor blades sweep out the full bore of the meter except for a small tip clearance space . As the blade tips pass the magnetic pick up they initiate a pulse . Flow rate is determined by the frequency of the pulses and Totalised Flow is obtained by summing the pulses . “ Fluidwell “ Totalisers , which sum the pulses automatically and display Flow Rate and Total Flow instantly on the readout can be mounted on the Turbine or fitted remotely .
F112 Flow Rate Totaliser unit can be fitted to the GFT turbine meter series to provide and flow rate and total display, 4-20mA flow rate output, and pulse output for flow total.
