Recommendations for online insert-type density meters
Thread Content
Which companies are good at producing online insert-type density meters, which are mainly used in evaporation processes?
Can’t a hydrometer generally be used to measure the density of liquids?
Just one, and what about the others? They’re ridiculously expensive.
Generally, it’s not possible; high precision is required, and the operating conditions are also quite complex
Could the original poster tell us which one it is? How much is one approximately?
Our company uses E+H and Thermo (Thermo Fisher), but these are mainly used for measuring liquids in pipelines; you might want to inquire whether there are any insert-type models available.
For measuring liquids, we have used Emerson and E+H models, which are fork-type
You, you idiot, spend your days promoting those two B-series watches of yours, but you don’t actually do anything useful. Although you didn’t provide any data on steam testing, at least you gave some directions for further investigation. Idiot.
There are various principles for online density measurement: 1. The isotope radiation principle; 2. The tuning fork vibration principle; 3. The U-tube vibration principle (similar to Coriolis mass flow meters, but with higher precision); 4. The liquid level differential pressure method; 5. The ultrasound principle. Such instruments depend on the properties of the medium, the operating conditions at the site, as well as the required accuracy of the measurements. What you mentioned is used in the evaporation process. During evaporation, there is the mother liquor or raw material liquid that is being evaporated, the concentrated liquid resulting from evaporation (which may contain fine crystal particles), and steam (as the density of steam is related to its calorific value). What medium do you want to measure?
Alumina industry? That one is tricky; it has crystals, and density meters hate that the most
