Vortex flow meter
Thread Content
For a vortex flowmeter used to measure steam, what happens to the instrument’s output when water passes through it for a short period of time? Solve
The vortex flow meter is a velocity-type flow meter; when water is present in steam, forming a steam-water mixture, the number of vortices detected by the vortex flow meter becomes unstable, varying either greatly or slightly, which results in large fluctuations in the readings. My personal understanding........
Not quite understanding, showing concern, let’s learn*learn*!
In conditions where the flow velocity is high and the pressure is low, the mass flow rate shown is very low; many domestically produced vortex flow meters do not respond in such situations.
The occurrence of \"missing pulses\" is due to larger droplets hitting the vortex generator, which prevents the formation of vortex rows. Therefore, when using a vortex flow meter to measure steam, the drain should be arranged properly~~
I’ve learned it. Can I understand it this way? In the case of a vortex flow meter used to measure gases, if the gas contains liquid, that is, it’s a gas-liquid mixture, it will cause large fluctuations in flow rate. Is there any pattern to these fluctuations? ?
I don’t think there’s any pattern.....
I’ve learned it! I’ve learned it! Anyway, there will be fluctuations; hurry up and write it down in your notebook. Hahaha
I have another question: to measure the resistance of the sensor wires in a vortex flowmeter, is it necessary to remove the circuit board in order to take measurements there, rather than measuring the resistance of the two-wire signal lines?
If it’s impossible to make a measurement without removing the circuit board, then remove it and take the measurement...
In that case, it should be causing the measured value to decrease, right?
