Seek measurement method for sodium hydrosulfide storage tank level gauge
Thread Content
Sodium hydrosulfide, due to its volatile and crystalline properties, prevents many types of level gauges from functioning properly over extended periods of time. If any expert has good methods, please feel free to share them! :handshake
Temperature, pressure, top-loading or side-loading.
Use an insert-type double-flange level gauge; it’s less prone to crystallization, and other types are difficult to use when crystallization occurs. If you have the money, go for a gauge that uses nuclear radiation, though it requires more maintenance
Thank you for your answer! To date, we have used radar level gauges, double-flange differential pressure transmitters with male die plates, as well as externally mounted magnetic flap level gauges – none of them have yielded satisfactory results, as they get clogged after a short time.
It is a atmospheric-pressure storage tank, with a temperature in the dozens of degrees. It can be installed on the side or from above, with an installation opening in both cases.
The tank is not large, so a top-mounted magnetic flap level gauge could be considered.
There’s no good solution; the only option is to use a radioactive level gauge.
What is the pressure of the gas phase above the liquid surface? What is the temperature of the liquid material? Is there a mixer in the tank? These three points need to be clarified properly...... For 20 years now, I’ve been using level gauges and density meters with pressure-sensing diaphragms that are not in contact with the liquid, to deal with liquids containing severe crystalline deposits – such as desulfurization lime slurry, or electroplating wastewater that is heavily scaled and corroded. The results have been excellent; as a result, I often have to deliver and sell large quantities of these devices{:2_32:}
Finally, please take a look at the radio frequency admittance level gauge that doesn’t suffer from scaling :lol
It can be weighed and measured, unaffected by the type of medium.
See if the weight-type level gauge is suitable
