What kinds of tables are good for the measurement interface? Seeking advice from experts
A regular float will do; there are also radio frequency admittance level gauges, magnetostrictive level gauges, guided wave radar, and so on
Capacitive level gauges are the cheapest, but also the least profitable; that’s why no one mentions them
Depending on the properties of the medium, if it is magnetic, a magnetic flap level gauge can be installed directly for local monitoring; if remote transmission is required, an output of 4-20MA signal is necessary. The liquid level can also be measured using a differential pressure level gauge.
Both magnetic level gauges and electric float level gauges are suitable for use in our company. It is important to note that the specific gravities of the two media must be selected accurately.
Liquid-liquid two-phase: Capacitance, or radio frequency admittance, can be used to measure the interface; physical calibration is required； Guided wave radar can measure interfaces, requiring a difference in dielectric constants between the upper and lower layers. Liquid-solid two-phase: Based on the principle of ultrasound, similar to sonar.
Floats are used quite a lot! ! It’s not expensive either!
Dual-flange level gauges are the better choice; it seems that none of the others are as suitable as them for now
The description isn’t clear enough – what type of medium is the page on?
