Seeking advice on level gauges
Thread Content
The company currently has a sink and a sealed tank; the medium inside is acidic water along with phosphogypsum sludge. Steam is supplied to the tank from above. What type of level gauge would be suitable for use here? Initially, a radar level gauge was used, but the presence of steam caused water droplets to form, leading to inaccurate measurements. A differential pressure gauge was tried instead, but the sludge caused blockages at the flanges, making accurate measurement difficult as well. I would appreciate advice on what alternative level gauge could be used ?
Isotope level gauges are devices that are not affected by any external factors. Just ensure proper safety measures are in place.
If the page fluctuations are not significant, you can try magnetostriction
1. On the existing foundation, add a flushing ring between the two flanges; use flushing fluid to keep flushing, with flow rates on both sides measured by rotameters. 2. Switch to an extended double-flange level gauge. 3. If the pressure inside the tank is not high, it is possible to modify the structure of a radar level gauge by introducing a nitrogen/compressor supply to continuously purge the antenna; some brands offer radar level gauges with such purge ports, and it is advisable to install a check valve in the purge pipeline. 4. Use a radiation-based level gauge, although this option comes at a higher cost.
How about floating balls? As long as corrosion protection is proper, it’s fine
Ultrasonic level gauges, I guess; magnetic flap level gauges are likely to be affected
Use a diaphragm-sealed level gauge; consider using a corrosion-resistant material for the diaphragm
There are simple and effective options for “float level gauges”; it’s hard to say anything else about them. Some of them come with remote transmission capabilities
I checked other answers, and they don’t seem accurate. With float level gauges, the presence of sediment doesn’t necessarily mean they will work properly; the same is true for magnetic flap level gauges. Ultrasonic level gauges are even less suitable, and pressure-type gauges are not an option at all. In the end, radar may still be the best option, but auxiliary equipment needs to be added. The temperature, pressure, range, and other conditions of the actual environment are unknown. Only if the parameters are confirmed will there be more options. Don’t ask me why I say so much, because I’m the one who manufactures level gauges – for almost 20 years now
