Question:

Where is the difference between a metal tube float meter and a vortex flow meter? Is it a metal tube float that is mechanical and a vortex street an electronic instrument?

Where is the difference between a metal tube float meter and a vortex flow meter? Is it a metal tube float that is mechanical and a vortex street an electronic instrument?

Answer:

The metal tube rotor flowmeter is mainly affected by density when measuring liquid, and it is affected by density, temperature and pressure when measuring gas. Vortex flow meter belongs to speed flowmeter. The rotor flowmeter can also be used for remote 4-20mA output
Moreover, the float is mainly in place, but also a small number of belt remote transmission, but the vortex must be with electronic conversion, part of remote transmission. The float can be made very small, the vortex street will not work; the float does not have the straight pipe section request, the vortex street has. The precision vortex street is high, and the vortex street has no moving parts and has long service life.
That's understandable... The vortex street is an electronic probe with an inductive Carmen vortex in the pipeline. The metal tube float flowmeter is the scale of the gravity balance between the force balance buoyancy and the rotor to realize the instantaneous flow measurement
