HM 500.11

Vortex Flowmeter with Digital Display

Technical Description

In a vortex flowmeter, the phenomenon of the so-called Karman's vortex is utilised. Behind a body in a flow, vortexes separate off. The frequency of the separation of the vortexes generates local partial vacuums that can be measured by means of capacitance. From this pressure data, which is converted by electronics into a scaled output signal, the flow speed or flow rate can be determined. A digital display for the indication of the measured data is integrated into this unit.
