8) Full metal case (IP67), sealed, alkali resistant, meet harsh environment.

3. Measuring principle: Time-of-flight method

The level gauge consists of an ultrasonic probe and an electronic tube. The unit-level instrument is installed at the top of the container. Under the control of an electronic device, the ultrasonic probe transmits ultrasonic pulses to the object to be measured. The sound wave is reflected by the surface of the object, and part of the echo received by the detector is converted into an electrical signal

The signal meter measures the time between sending and receiving pulses. Time is proportional to the distance from the probe to the measured object. The electronic device detects this time and calculates the measured distance according to the known sound speed. The level value can be obtained by subtraction.

4. Technical data:

Basic data

Note: When using to measuring solid level, the most energy of ultrasonic is absorbed or scattered by solid level, so the back wave is very little, the valid measuring range of solid level is about 50% of liquid level. And the valid measuring range of solid level is determined by the installing location and rang.

The blacking distance:
