Ultrasonic level transmitter is a non-contact, high reliability, cost-effective, easy to install and maintain liquid level/material level measure instrument. It can meet most liquid level/level measurement requirements without contacting the measured medium.
Measure range: 5~50m(optional)
Blind zone: 0.3m
Accuracy: ±0.5%FS, ±1%FS
Power supply: 220VAC, 50Hz; 24VDC, 120mA
Ultrasonic level sensor can be divided into two types according to the structure form: integrated type and split type. Split-type ultrasonic level transmitter is the meter head and transducer are installed separately, and the meter head and transducer are connected with wires. Split-type ultrasonic level sensor is suitable for complex environmental occasions such as not easy to maintain, debugging, etc., and the functions of bus communication and switch output on the meter head can be used for transmission and remote control.
