Which densimeter is suitable
Thread Content
Anhydrous sulfuric acid solution, at room temperature. 316L material can resist it. Diaphragm differential variation and mass flow rate method have been used for measurement. Both of these require contact with a medium, and when they get dirty, it affects the measurements. Are there any other good maintenance-free methods? Vibrating type, Heizhu brand air-concentrating type? To what extent does the amount of liquid affect the amount of dissociated gas?
There is a type of nucleon densitometer with a lifespan of around 10 years, and it performs non-contact measurements.
There are radioactive contactless density meters, with Na-22 as the radiation source; those that come with an exemption certificate do not require approval and are harmless to the human body. The manufacturer’s contact information can be provided
