AMG-UR9812 High precision Sludge Interface Instrument

AMG-UR9812 High precision Sludge Interface InstrumentProduct Overview:
AMG-UR9812Ultrasonic sludge interface analyzer/The mud level meter (hereinafter referred to as the instrument) is an online mud water rangefinder with a microprocessor. Measurement of sludge interface in sedimentation tanks, secondary sedimentation tanks, and sludge concentration tanks for sewage treatment; Mud level determination for sedimentation tanks in water plants, as well as for sedimentation tanks in water supply plants, sand washing plants, and power plants (mortar sedimentation tanks).
AMG-UR9812Ultrasonic sludge interface analyzer/Working principle of mud level gauge:
AMG-UR9812Ultrasonic mud water interface measurement is carried out by an ultrasonic sensor installed in water, which emits a beam of ultrasonic pulses to the surface of the underwater mud. This pulse signal is reflected back when it encounters the mud surface and can be received by the sensor again; The time from ultrasonic emission to re reception is proportional to the distance from the sensor to the surface of the object being measured; The instrument detects the time and calculates the distance (i.e. spatial distance) from the surface of the object being measured to the sensor based on the current temperature (measured by the sensor) and underwater sound velocity, and further converts it to the liquid level value. The empty underwater distance of the liquid level surfaceWTravel time with sound wavesTDirectly proportional:W=V×T/2(Among them)VThe speed of sound waves in water.
