Advantages of external level gauges

Thread Content

The external level gauge represents a true non-invasive measurement technique; its sensors are installed at the bottom and side walls of the container； Fast, reliable, and high-precision container volume measurement ； Easy to install, without the need to damage the container ； There is no need to shut down the equipment during the installation of the external level gauge ； External level gauges have no moving parts and require almost no maintenance. Two compact external level gauge ultrasonic sensors are installed, one at the bottom of the tank and the other on its side wall, to compensate for changes in density. The signal from the external level gauge sensor is processed by a microprocessor and sent to either a local display or the user control system. It is possible to calculate the height of the liquid in the tank as well as its volume.
