The HLVD series ultrasonic liquid level transmitter is a streamlined liquid level measuring instrument. It is composed of a built-in ultrasonic sensor and an electronic unit. It leads out a cable and is a standard two-wire 4-20mA signal output. Its power supply (DC24V) Shares the same circuit with the signal output. Since the sensor signal has been processed inside the probe, it has strong anti-interference ability. Sensor materials can be selected from ABS, PVDF, and PTFE anti-corrosion materials to adapt to harsh industrial application environments. The transmitter uses dynamic power control technology to constrain signal strength and beam angle, and uses unique echo scanning technology to identify real signals. The measurement is accurate, stable and reliable, and is widely used in various industrial fields.
HLVD series ultrasonic liquid level transmitter is an economical and practical method of liquid level measurement, using the same technology as ultrasonic level meters.
