For submersible hydrostatic level gauges, do you have any good recommendations?
Thread Content
First, let’s ask a few questions: First, regarding the medium being measured – normal-temperature sewage and acids or bases at a 30% concentration – how effective are electrodes made of stainless steel 304? Second, what form will the diaphragm take? Is ordinary 316 better or diffused silicon? Third, everyone please help recommend some brands. Thank you
Cement tanks, when installed, are not sealed containers.
For corrosive media, try to avoid contact-type sensors; if the conditions are normal temperature and pressure, an ultrasonic level gauge will suffice
For submersible sensors available on the market today, the probe material is usually 316L, which can handle weak acids and bases without issue. As for the diaphragm you mentioned, there seems to be some confusion here; it should refer to capacitive or diffused silicon types, as these are two different measurement methods. The 316L material you mentioned is likely referring to the diaphragm itself. Other corrosion-resistant materials include Hastelloy, nickel alloys, Monel, and tantalum. As a recommendation, the E+H FMX21 series could be used
It’s a big problem only in an environment of weak acids!
Hehe~~ I use a pressure transmitter here; a properly sealed tube is used for connection below, and once it’s placed in the tank, it’s ready to use. I’ve been using it for years now
Whether it is acidic or alkaline – this is an important issue regarding wastewater. Remember to be meticulous no matter what job you are doing; it doesn’t matter if you do a little less work.
