Explosion Proof Ultrasonic Level Meter Fuel Level Sensor With
26.2ft Range
1. Application:
The series is an integrated two-wire ultrasonic level meter
continuous contactless liquid level measurement of liquids and
solids. It consists of probes and electronic devices, both of which
are leak-proof structure. This series of products can be widely
used in metallurgical industry,
chemical, electricity.
2. Working Principle
Ultrasonic principle:
Ultrasonic sensors emit short, high-frequency sound pulses at
regular intervals. These propagate in the air at the velocity of
sound. If they strike an object, then they are reflected back as
echo signals to the sensor, which itself computes the distance to
the target based on the time-span between emitting the signal and
receiving the echo.
3. Technical data:

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 |
