Exploration of density-independent level gauges, ignoring digital signals
Thread Content
RT, I’ve been troubled recently by the issue of choosing a level gauge. I’m interested in knowing what level gauges are available that are not dependent on density, so that I can select one suitable for use. Thank you to all the engineers who will provide replies
Use a float level gauge; it should achieve the effect you want. Ultrasonic waves and radar work too.
RF admittance type capacitance level gauge, ultrasonic level gauge, guided wave radar level gauge, magnetostrictive level gauge. Everything that makes use of buoyancy is related to density, right? Why do you do it this way? Can’t differential pressure be used instead?
When the density component changes, the dielectric constant also changes; the admittance is still related to density
Since the density of the solution changes over time, anything that depends on density won’t work. The container is multi-stage sealed, so radar, ultrasound, and similar methods probably won’t work either
Level measurement that does not involve direct contact is radiation-based; it requires multiple seals, and there must be pipes for inlet and outlet. What about differential pressure measurement? Can’t temperature and pressure compensation be used?
