FLOWTECH Piston type Positive Displacement Meter is intended for general in line Volumetric Consumption applications for any Clean Oil. These flowmeters work on the volumetric principle of ring piston meters, the main futures of these meters are large measuring ranges, high accuracy, suitability for high viscosities and independence from power supply. The number of revolutions therefore is directly proportional to the measured volume. Transmission gearing transmits the revolutions of the Piston to a mechanical register which counts the flow in volumetric units (Liters, Cubic Meters, and Gallons etc.) Line sizes 4 mm to 15 mm (1/8 inch to half inch ) and are suitable for up to 25 Kg/Cm2 Pressure and 130 o C Temp., Viscosities up to 1000 cP, Accuracy : +/- 1 % of actual flow. Accessories : Mechanical Register (Reset type and Non reset type) & Strainer.
