The HLG series ultrasonic liquid level difference meter is a non-contact liquid level measuring instrument. It is often used in the sewage treatment industry. It uses the principle of sound wave reflection to detect the liquid level before and after the dirt barrier and calculate the liquid level difference. It can also be used for dual liquid levels in other occasions. Or liquid level difference measurement. The instrument consists of dual ultrasonic probes and a host computer, both of which are fully plastic sealed structures. They are suitable for measuring liquid level and liquid level difference in municipal sewage or water treatment in petrochemical, metallurgical and other industries. The instrument 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.
The HLG series ultrasonic liquid level difference meter is rich in functions and can be equipped with a variety of ultrasonic probes.
