Doppler type flow meter for saturated steam

[gedomin]

Has anybody experience or know about a supplier of a Doppler type flow meter for saturated steam ?

Yes, but only if other proven technologies can't be used. Certain ultrasonic flow meter manufacturers have specific electronics designed for gas/steam flow measurement.

Doppler is often a risky flow meter selection in easy applications. Steam does not sound like a good fit for a doppler flow meter.

Doppler requires droplets so that there is something upon which for the sound waves to reflect. No droplets if the steam is dry.

A similar concept is time-of-transit, but it works on dry fluids. There is an emitter on one side of the pipe. Upstream, on the opposite side of the pipe, there is a receiver, and an identical receiver the same distance downstream. The difference in time betwheen when a ping hits the upstream receiver and the downstream receiver is directly a function of the velocity, thus a function of the flowrate.

Perhaps it's better to apply an vortex flowmeter for this:
