I encountered an on-site problem. If you have seen it, please come in and take a look and help me.

Yesterday I went to the site for a small renovation project and found that there is a single flange liquid level transmitter installed at the bottom of the tank. There is also a local instrument similar to a pressure gauge at the same level. It has three pointers. According to theory, it should be an indicator that converts pressure into liquid level. According to the owner's request, the new instrument must be the same as the original instrument. This local meter has not been used and does not have a camera. I don't know if any of you have used this thing. What is it called? Do you have any relevant information? :loveliness: Thank you for this post. Finally, hwindforce Edited at 2009-3-1 14:46 ]
There are no pictures, so it’s hard to be sure. Please describe in detail.
Is it an electric contact pressure gauge? ? This post was last edited by lijing0347 on 2009-3-1 17:50 ]
My original workplace seems to have this kind of meter, which is called KF when used on propylene tanks. The given instructions are used for on-site adjustment. Is it helpful to you?
It is a field meter without a signal line connection. It looks like a pressure gauge. The three needles on the dial have scales, but they are too old to see clearly the words on the dial. Can anyone guess what it is?
I wonder if it is a pressure gauge with a positioning or limit adjustment function to roughly indicate the position of the liquid level relative to the full scale. For example, HIGH HIGH is 1 meter LOW LOW is 0.2. Then adjust the pressure gauge according to the density converted into pressure. At 0.6 meters, the movable pointer will be in the middle of the upper and lower pointers. Has anyone used it? :( This post was last edited by hwindforce on 2009-3-1 22:54 ]
I seem to have seen electric contact pressure gauges with three pointers. One is for displaying pressure, usually black, and the other two are metal for upper and lower limits.； But they are all equipped with electric shock output. Without wiring, they can be used as ordinary pressure gauges. Can you see the units on the table clearly? Determine the measuring range. If appropriate, convert the pressure of the measuring tank into liquid level. Check if it has contact output?
There is no contact output, and there is no wiring. I guess it is just a tool for roughly displaying relative and upper/lower liquid levels. This post was last edited by hwindforce on 2009-3-1 23:03 ]
Do you have any photos? It’s hard to judge!
To determine the liquid level range, just find a pressure gauge instead.
This is a local liquid level indicator
Back to the first floor, everyone's replies should not be of much help to you. Instrument selection cannot be based on guesswork. In addition to the instrument type, there are also specific models, ranges and other parameters. It is recommended that you still determine it yourself based on the on-site table. :handshake
I figured it out, that thing is called a pressure level gauge.
brother: Is your horizontal tank an open vessel or a pressure vessel? A single flange cannot measure the liquid level of a pressure vessel. There are three-pointer pressure gauges, including memory pressure gauges/electrical node pressure gauges. There is no picture. Please upload this post. Last edited by longniu on 2009-3-3 13:13 ]
The three-pointer is probably an electric contact pressure gauge, one indicates pressure, and the other two are the setting pins for high-voltage alarm electric shock and low-voltage alarm contacts. You can post the model number so everyone can take a look!
It's best to send a picture to make it clearer. You can also take a look at the product nameplate.
Brother, why can’t the single flange negative pressure chamber be connected to the gas phase to measure the pressure vessel?
‘ This thing is called a pressure-type liquid level gauge, which is very similar to an electric contact. The only difference is that the liquid level displayed on the dial is converted from pressure. It is actually a diaphragm pressure gauge with a limit adjustment device. . . Compared with electrical contacts, there is no contact output
Chlor-alkali device, only rust can be seen
I suspect it is a differential pressure gauge that measures differential pressure and has an upper and lower limit alarm switch, so the three pointers
