Explosion proof and anti-corrosion ultrasonic liquid level gauge, high-precision, low blind area, non-contact type

The working principle of an ultrasonic level gauge is that high-frequency ultrasonic pulses emitted by a transducer (probe) are reflected back when they encounter the surface of the measured medium, and some of the reflected echoes are received by the same transducer and converted into electrical signals. Ultrasonic pulses propagate at the speed of sound waves, and the time interval required from emission to reception of ultrasonic pulses is proportional to the distance from the transducer to the surface of the measured medium.
The non-contact measurement characteristics of ultrasonic level gauges make them suitable for measuring the liquid level in various open containers, as well as for measuring the water level in channels, reservoirs, rivers, lakes, and seas. They are particularly suitable for sewage and corrosive environments. The instrument can not only measure accurately, but also continuously measure and record hydrological data in detail, avoiding the danger of looking at the water level gauge manually when going to the water in rainstorm and flood season, greatly reducing the labor intensity of hydrological observation personnel, and improving the scientificity and accuracy of monitoring.

Ultrasonic liquid level meters are commonly used in remote data collection and monitoring systems for drainage pumping stations in cities and large schools. They automatically monitor the water level in front of and behind the trash racks of pumping stations distributed in cities and schools, as well as the water level in water plant dosing tanks. They are used for sewage discharge and environmental purification in cities and schools, achieving good social and economic benefits.
