Renovation of single-flange level gauges for storage tanks
Thread Content
There is a storage tank at the site of the installation. Initially, the top of the tank was designed to be open to the atmosphere; it was later modified so that the gas phase at the top of the tank is connected to a gas collection system, with a slight positive pressure of 1 KpaG at the tank’s top. However, the level gauge in the tank remains a single-flange type; slight fluctuations in pressure at the top of the tank during use cause false readings of the liquid level. Without replacing the gauge, it is possible to convert it to a double-flange type by using pressure transfer pipes to connect the gauge’s negative pressure side to the gas phase at the top of the tank. It’s not clear whether this approach will work. . . . . I would appreciate some advice from everyone.
You need to test whether the negative pressure side is working; for example, press the negative pressure port with your thumb – if the reading changes, then it’s possible to use it.

Yes, I thought of that – connect a tube to the negative pressure side and pour some water in!
Sure, what is the temperature of the medium and what is the nature of the medium? If you provide these details, I can help you design it more effectively:lol I have modified many of these devices; for those used to measure slurries, I opted to use differential pressure in the design
If the transmitter is fine, then your solution is definitely okay.
Haha, it’s just a wastewater tank; there are dissolved organic substances in it, and the temperature is 50-60 degrees – it’s not that difficult

You’ve provided valuable guidance; the gauge is fine. It’s possible to use a sealant inside it, which can significantly reduce the amount of maintenance required. Moreover, this single-flange modification has helped the unit save a considerable amount of money – it deserves to be recognized
