Vortex Flow Meter

Category Vortex Flow Meter Size: DN15~DN300mm (flange) Signal output: Pulse, 4-20mA, Hart, RS485

INTRODUCTION

Steam flow measurement is a kind of velocity flowmeter. It is based on the Karman vortex street theory and uses piezoelectric crystals to detect the vortex frequency generated when the fluid passes through the triangular column in the pipeline, so as to measure the flow of the fluid. Steam air flow measurement are widely used in petroleum, chemical, power heating and other industries.

APPLICATION

Steam flow measurement is always used in measuring steam with high temperature, it also can be used in most kinds of gases like nitrogen, methane, hydrogen, air, compressed air. Because of its accurate measurement, it can also be used for gas trade settlement.

It can also measure liquids. We should pay attention to avoid vibration while use air flowmeter.
