Positive displacement flow meters with conditioned output Up to l 150 lpm, 40 US gpm l 420 bar, 6000 psi Milwaukee, WI 53235, USA Tel: +1 (414) 769-6400 sales-us@webtec.com St. Ives, Cambs. PE27 3LZ, UK Tel: +44 (0) 1480 397 400 sales-uk@webtec.com The GF series gear type flow meters are ideal for precision measurement on medium to high viscosity hydraulic and lubrication fluids, or in applications where the fluid viscosity can change substantially due to large variations in temperature. The GF series are positive displacement flow meters with a conditioned output, that are designed for measuring flows on hydraulic and lubrication systems, on test stands, machine tools and other fixed or mobile applications. The GF flow meters offer high accuracy and excellent viscosity stability and can be installed anywhere in the circuit for monitoring, production testing, commissioning, development testing and analysis of control systems. The compact design allows the GF series flow meters to be installed where space is limited. The GF gear type flow meters have a built-in micro-controller that linearises and conditions the signal from the flow meter to provide an accurate and linear output signal. This enables you to connect the flow meter directly into your digital display, PLC or custom DAQ system without having to worry about complex calibration factors or lookup tables. Features l FLOW: 0.1 – 150 lpm, 0.03 – 40 US gpm l PRESSURE: up to 420 bar, 6000 psi. l OUTPUT OPTIONS: 4-20 mA & pulse (both linearized) l BI-DIRECTIONAL operation l CALIBRATION: 21 cSt as standard. Special calibration possible. Calibration certificate supplied as standard. l FLUIDS Oils, fuels, water glycol, water oil emulsions, phosphate esters. l STAINLESS STEEL Body, gears and transducer as standard. Symbol * Units are delivered with male to male fitting to provide thread form stated over Hydraulic measurement and control
