VAF PT2 Vane FlowMeters are used in continuous metering applications. The positive displacement sliding vane type liquid Flowmeters have a simple, rugged design. With only few almost frictionless moving internal parts there is hardly any wear in the Flowmeter which safeguards a typical long lasting lifetime. PT2 meters have no mechanical seals saving you from regular maintenance and possible leakage of process liquids into the environment.
The VAF PT2 Vane FlowMeters are driven by the process liquid which makes it suitable for distant locations without power supply. The high accuracy of the Flowmeter (better than 0,2% and repeatability 0,05%) is not influenced by process pressure or temperature, mechanical pipe strain or liquid turbulence and therefore straight inlet and outlet pipe pieces are not required.
In 1938 VAF Instruments started as a manufacturer of petrol delivery pumps. The Flowmeters made by VAF Instruments for this pump already had to have the highest accuracy and had to meet the demands of the board of weights and measures. Innovation and research over the past decades helped VAF instruments to make new types of Flowmeters bearing in mind customer requirements and the need for accurate flow measurement. VAF Instruments Flowmeters are available in sizes from 8 mm up to 300 mm (1 l/hr up to 960 m3/hr).
