Turbine flowmeter system measures bi-directional flow TEMPE, Ariz., December 1, 2009 –

The flowmeter measures bi-directional flow in a wide range of liquid applications. This advanced system can also compensate for viscosity changes due to variations in ambient fluid operating temperature, which affect the accuracy of flow measurement data. Employing the turbine flowmeter system provides bi-directional flow measurements in a host of hydraulic, pneumatic and pumping applications. The flowmeter is an ideal choice when high accuracy, compact size and fast response are critical. The flowmeter houses a sophisticated electronics platform for flowmeter linearization, viscosity correction and density compensation. With the system, a turbine flowmeter with a bi-directional Universal Viscosity Curve (UVC) calibration employs dual RF/RTD pickoffs for determining flow direction and sensing temperature. The system’s innovative, temperature-compensated linearization technique reduces viscosity effects on K-factors by calculating fluid viscosity through real-time temperature measurements and proper calibration methods. As an alternative, the system can be employed with the manufacturer’s flow computer. This powerful unit can be configured to display volumetric or mass units of measure with UVC and Strouhal-Roshko temperature compensation for variations in viscosity and density due to temperature. The unit can output a 4-20 mA flow measurement signal to the user''s data acquisition system and display digital read-outs via a panel-mount display.
