Plate voltage drop measurement? I’ve decided to use a differential pressure sensor. How can I lower the temperature?
Thread Content
I need help from experts: For a gas-liquid countercurrent plate tower, how is the plate pressure drop measured? ? How to install a pressure sensor? ? It’s still a differential pressure sensor! ! ! Thank you! ! Thank you all for your enthusiastic responses; I have already contacted the manufacturer of the differential pressure sensor. But the problem now is that since our medium is steam, the temperature is above the range that the pressure difference sensor can handle. Are there any good ways to reduce the pressure? The preliminary decision is to add an extension tube. Please share your opinions. Thank you. This post was last edited by kisml on 2009-3-18 09:53]
It must be a differential pressure sensor; the pressure drop is so small!
It’s not necessary to use this; a pressure drop of a few Kpa is sufficient. A high-precision on-site pressure gauge can be used for calibration, and such gauges are usually available in the instrument management departments of ordinary factories.
Check the changes in the pressure difference between the bottom and top of the tower.
It can be measured using a simple, homemade device; just use a pressure gauge with high precision, connect tubes to it – one end connected to the pressure gauge and the other end to a cork. Generally, there is a DN25 valve on the tower used to measure the pressure drop in the tower. Placing the cork over the outlet of this valve prevents steam from leaking, and by opening the valve, the pressure can be measured
