Kaidi KD HRS400 Ultrasonic Level Meter IP65 used in electric power

HRS400 ultrasonic level gauge is a non-contact, low-cost and easy-to-install level gauge. It applies advanced aerospace technology to the general livelihood industry. Unlike ordinary level gauges, ultrasonic level gauges have more restrictions. The products are durable and durable, simple in appearance, single and reliable in function, and are used in electric power, metallurgy, and petroleum. Chemical, food, water treatment, paper making and general corrosive liquid level measurement.

1. Large measuring range, high precision and low energy consumption;

2. Non-contact measurement, no moving parts;

3. It can measure liquids and solids;

4. Adopt scientific echo tracking algorithm to effectively capture the true echo;

5. The internal temperature compensation (speed, frequency) makes the measurement more accurate and reliable;

6. Analog quantity, switch output;

7. The measurement is not affected by the liquid density and the electrical characteristics of the material;

8. Severe fluctuations or foam liquid have no effect on the measurement;

9. Electronic equipment can be replaced without opening the tank

①Material level measurement

②Distance measurement

③Storage capacity indicator

④ Differential measurement

⑤ Pump control

The working principle of the ultrasonic level meter is that the ultrasonic pulse from the transmitting head meets the surface of the measured medium and is reflected back, and part of the reflected echo is received by the same transmitting head and converted into an electrical signal. The time interval required for the ultrasonic pulse is proportional to the distance from the transmitting head to the surface of the medium. The relationship between the distance value S and the speed of sound C and the transmission time T can be shown in the table: S=CT/2
