Using piezoelectric principle, converters can receive temperature sensor signal and pressure sensor signal. It can detect and control the various liquids, gases, high / low temperature saturated steam and superheated steam to flow measurement.
Characteristics
1) Shock resistance type: The vortex flowmeter of Fischer & Porter Corporation adopts 4- piece piezoelectric crystals for measuring. Two of them are used to detect the flow of fluid. The other two are used to detect the vibration signal of pipe.
2) Temperature and pressure compensation
3) Intelligent type: The meter parameters and meter range may be changed by three manual buttons, magnet bar or manual controller on site.
4) Output mode: 4-20mA current signal output/ pulse signal and contact signal.
