Ultrasonic Level Sensor for Fuel Oil Tank / Water Level Made in
China
1. Application:
The series is an all-in-one two-wire ultrasonic level meter,
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) Body design, easy to install;
3) Over voltage and 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 can meet all kinds of work occasions
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.

| Output current | 4-20mA |
| Output load | 0-500Ω |
| Temperature range | -40℃~80℃ |
| Pressure range | ±0.1MP (press definitely) |
| Measure cycle | 1 second (changeable ) |
| Beam angle | 8º(3db) for range :4m 6m 8m 5º(3db) for range :12m 15m 20m 30m |
| Parameter set up | 3 induction buttons |
| Cable connection | PG13.5 |
| Material | The electronic unit : metal The sensor: ABS |

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 |
