Pressure tapping issues for differential pressure transmitters
Thread Content
Today, I saw that the differential pressure flow meter used by the company was used to measure the flow rate of silicone oil; the pressure tapping ports were oriented upward, and there was also a spiral pattern on them. The temperature of the silicone oil was estimated to be around 200 degrees. When measuring a liquid, isn’t the pressure port supposed to be facing downward?
It seems that there are impurities in this liquid, and I’m worried that these impurities might block the pressure measurement tube.
Upstairs, it’s been thought through very carefully; I wonder if it might really be a mistake in installation after all, hehe!
It shouldn’t be installed incorrectly, because it’s not the only place where it’s installed in that way
Generally, when measuring liquids, the pressure tap is placed facing downward; this is done to prevent the inability to detect the pressure difference when the tube is not filled with liquid. If it is installed in this way, then there must be specific requirements for measuring silicone oil! Looking forward to experts solving the problem!
It can’t be analyzed. The condition of the manufacturing process should be checked; logically, it should be facing downward. Looking upward, it makes sense to say that preventing blockages is important. Is there a coexistence of liquid and gas?
A three-valve assembly is used for installation; if there are many impurities in the medium, an isolation device can be employed.
