How is the level of a inclined plate settler measured?

What material is being measured? Material height (range)? Material temperature? Material pressure (pressure of the gas phase above the liquid surface)?

This post was last edited by maysee on 2018-4-26 at 10:46; an ultrasonic level gauge can be used. An ultrasonic level gauge detects the liquid level by utilizing the principle of ultrasound reflection at the liquid surface; in other words, it applies the principle of measuring distance through echoes. When an ultrasonic probe emits short pulses of ultrasound toward the liquid surface, after a time t, the probe receives the echo pulses reflected back from the liquid surface. Advantages of ultrasonic level gauges: 1) Ultrasonic level gauges enable non-contact measurement, and they operate in a stable and reliable manner ； The ultrasonic level gauge is installed above silos and tanks, without coming into direct contact with the material. 2) It has a wide measurable range; it can measure the level of liquids, solids, and powders. 3) It enables continuous measurement at fixed points, and can conveniently provide telemetry and telecontrol measurement signals. 4) It is simple and convenient to install, and no safety protection is required. Disadvantages of ultrasonic level gauges: 1) Ultrasonic level gauges have blind zones in their measurement range; when installing them, the transmitter probe must be positioned above the highest liquid level, within that blind zone. This ensures accurate monitoring of the liquid level as well as the safety of the ultrasonic level gauge. 2) In the case of foam present, ultrasonic level gauges suffer from significant inaccuracies in measurement, as sound waves cannot penetrate the foam and are instead reflected back by it. An antifoaming agent can be added to foam-containing tank containers to reduce foam formation and ensure accurate measurements. 3) Ultrasonic level gauges in containers equipped with agitators are affected by the agitator, which causes false reflected echoes and leads to inaccurate measurements. By reducing the speed of the stirrer and installing the level gauge away from the center of the stirrer, the influence of the stirrer on the measurement by the ultrasonic level gauge can be reduced. 4) The temperature of the medium being measured also has an impact on ultrasonic level gauges. Especially in enclosed containers, when there is a temperature difference between the temperature of the medium and the surrounding temperature, water droplets will form around the probe, which affects the accuracy of the measurement.

Those shortcomings mentioned on the 3rd floor can’t really be considered shortcomings at all; they’re more like cute quirks. . . :Lol, the real drawback of ultrasonic level gauges is that they act like intermittent maniacs. That crazy device, when it goes into ‘attack mode’, has four tricks up its sleeve: it reports an empty container as full, and a full container as empty; it makes the measured values appear as if the device is dead and motionless, or as if it’s a crazy dog that’s jumping around wildly. Every now and then, every ten days or so, it uses one of these tricks to tease and trick you. In any case, it’s impossible to figure out what’s going on with it – its ‘crazy powers’ are greater than your intelligence; it’s just lying to you :lol. .
