Experts asking for help, our decompression tower uses a floating bucket with a range of 1.6M for the third line, but the liquid level does not change much. Both the upper and lower pressure pipes are connected. The negative pressure inside the tower is about 80KPA. After all the upper and lower valves are cut out, the exhaust can A lot of medium comes out, and it feels like it's between 80% and 90%. But there is another liquid level gauge with double flanges, and it only measures 20%. The double flanges are removed and checked, and there is no problem. I feel that there is no problem with the floating tank itself. Is it affected by negative pressure? ? ? Open the valve first, and the float slowly rises to about 80%. Then open the valve next time, and the liquid level basically does not change. However, after the upper and lower branches are cut off, a lot of media can be released. When discharging, the float also slowly drops until it drops below 0. I have not solved this problem for many days. I don’t know whether to believe the double flange or the float. The key is that there is no on-site liquid level meter. Can any expert analyze it?
1. Under vacuum, the double-flange differential pressure gauge cannot accurately measure the pressure difference! . . . If the measurement is accurate, it will be a miracle. . . Look at the picture. The picture is posted by Haiyou. The text in the picture is added by me. 2. Under vacuum, could it be that the float level gauge cannot measure the buoyancy accurately?
Our little factory's Shuaike vacuum negative pressure level gauge can measure accurately. It’s as accurate as if I was peeing. If I said I was peeing in the toilet, I would ejaculate into the toilet. Not even a drop of water would miss the outside of the bucket... :lol.
Just recalibrate it and see again. You didn't say what liquid level the float shows. Who can analyze it? Also, a friendly reminder that the store upstairs sells refurbished watches.
Check whether the lock under the transmitter is open. The float level gauge needs to be calibrated before being put into use.
Calibration is a measurement method to solve the drift and misalignment of instruments. As for the two liquid level gauges mentioned by the poster, they seriously deviate from the true value and cannot reflect the changing trend of the liquid level. What does drift have to do with it?! In this situation, if you encourage the poster to check the instrument, how many seedlings can be used? What is the use of doing useless work and wasted work? What is it going to do? . . If the medicine is not right for the patient, it is unreasonable and there is no basis for it. A lot of nonsense and 49205455 crooked words will only irresponsibly push people down the wrong path. Dog said he is very evil-minded,
The float level gauge can be tested with water on site to confirm whether the float is accurate. In addition, under negative pressure, the double flange measurement is inaccurate and easily damaged.
Normally, the float should be fine. We all use large-angle float level gauges, which are very easy to use.
