Features of the Four-Wire Ultrasonic Level Meter

Dayu Electronics four-wire ultrasonic level meter is a non-contact level measurement instrument controlled by a microprocessor, which is easy to install and maintain.

It mainly operates using a four-wire output mode. That is, when powered by AC 220V or DC 24V, the power supply circuit must be completely isolated from the signal output circuit, and a four-core cable is used. The four-wire ultrasonic level meter consists of three parts: the ultrasonic transducer, the processing unit, and the output unit. During measurement, ultrasonic pulses are emitted by the sensor (transducer). The sound waves are reflected by the liquid surface and then received by the transducer, which converts them into electrical signals. The distance from the transducer to the measured liquid is calculated based on the time between the emission and reception of the sound waves.

1. Simple structure and easy installation;

2. High measurement accuracy. The measurement accuracy is up to 0.3%, capable of resisting various interferences with strong adaptability;

3. Stable and reliable product performance. The PVDF probe ensures reliable measurement even in corrosive liquids or environments;

4. Excellent sealing and high protection rating. The Uson-11 four-wire ultrasonic level meter has a protection rating of up to IP66/IP67;

5. High safety, suitable for measurement in flammable, explosive, and other hazardous situations. The Uson-21 flameproof ultrasonic level meter features a flameproof enclosure design and has been certified by the National Explosion-Proof Certification Center. Its explosion-proof rating is ExdIICT6Gb, allowing use in explosive hazardous areas;

6. High cost-effectiveness and low maintenance costs.
