Drum pressure
Thread Content
On the drawings of the boiler plant, there is a pressure measurement point on the steam drum as well as a pressure impulse sensor. Is it necessary to install pressure transmitters at both of these locations? What is the purpose of the pressure impulse sensor?
What does pressure impulse mean? I’ve never seen such a description
One pressure measurement point, one pressure impulse – how many are there in total?
It’s better to simply show the drawings so that it’s easy to understand.
Pressure impulse is used for three-impulse control of liquid level, right?
I’ve run into this problem too. . I’m not sure what it’s for – is it to install a pressure transmitter or a pressure gauge?
