Intelligent Ultrasonic Level Meter with 4 Digital LCD Display IP67
Protection Class
1. Application:
This series is an integrated two-wire ultrasonic level gauge
continuous non-contact level measurement of liquids and solids. It
consists of a probe and an electronic device, both of which are
leak-proof structure. This series of products can be widely used in
the metallurgical industry,
chemistry, electricity.
2. Features:
1) Compact continuous non-contact liquid level measurement;
2) Integrated design, easy to install;
3) Over voltage, over current protection, lightning protection;
4) Large LCD or LED display window, easy to debug and observe;
5) Strong anti-interference ability;
6) 4-20mA output;
7) Intelligent signal processing technology to ensure that the
instrument meets various working occasions
8) Full metal shell (IP67), sealed, alkali resistance, and meet the
harsh environment.
3. Measuring principle
Ultrasonic Level Sensor with Indicator emits ultrasonic pulses
transmitted through the transmission medium to the measured body
surface, the reflection and then return through the medium of sound
propagation to the receiver transducer to measure the ultrasonic
pulse from transmitter to receiver propagation in the medium of
sound propagation time. Sound transmission medium according to the
speed of sound, can be called from the transducer distance to the
object plane to determine the material level.

The measuring range:
| MODEL | MLT4 | MLT6 | MLT8 | MLT12 | MLT15 | MLT20 | MLT30 |
| LIQUID | 4.00m | 6.00m | 8.00m | 12.00m | 15.00m | 20.00m | 30.00m |
| SOLID | | | 3.00m | 5.00m | 7.00m | 10.00m | 15.00 |
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:
| MODEL | MLT4 | MLT6 | MLT8 | MLT12 | MLT15 | MLT20 | MLT30 |
Blacking distance | 0.20m | 0.25m | 0.30m | 0.45m | 0.60m | 0.80m | 1.20m |
