1Equipment Composition

IIEquipment principle

Ultrasonic sensors emit and receive ultrasonic waves under the control of microprocessors, and determine the propagation time of ultrasonic waves in the airCalculate the distance S between the ultrasonic sensor and the object being measured using tDue to the speed at which sound waves propagate in the airIf c is constant, then S can be calculated based on S=ct/2Also, due to the distance between the ultrasonic sensor and the bottom of the containerIf H is constant, then the liquid level of the measured substance is h=H-S. Due to the influence of temperature on sound velocity, instruments should measure temperature to correct for sound velocity.

IIIApplication scope

·Water and sewage treatment: pump room, collection well, biochemical reaction tank, sedimentation tank, etc;

·Electricity and mining: mortar pool, coal slurry pool, butter storage tank, material yard or partial mobile equipment control, etc;

·Food industry: distilleries, grain warehouses, food material storage tanks, etc;

·Used in conjunction with the control system.
