Flowquip industrial turbine flowmeters can be applied to a wide range of duties in the process industry measuring both lubricating and non-lubricating liquids of low viscosity. The all stainless steel construction gives good corrosion resistance. Furthermore the FT4 is largely unaffected by changes in liquid density and temperature. It is an economic flow solution offering outstanding accuracy with a bearing construction which gives highly reliable performance over long periods. Typical applications include the measurement of water, hydraulic oils and chemicals. The flowmeter has laboratory standards of accuracy so it is also used for testing the performance of pumps, jets, turbines, engines, valves and even other flowmeters. ATEX approval means the FT4 can be installed in intrinsically safe areas (EEx ia IIC T5) when fitted with an I.S. pickoff coil.
