Fuel Tank Ultrasonic Level Meter with PVC or PTFE Probe China
1. Application:
This series is an integrated two-wire ultrasonic liquid level
meter,continuous non-contact liquid level measurement of liquids
and solids. It is composed of a probe and an electronic device,
both of which are leak-proof structure.This series of products can
be widely used in metallurgical industry, chemistry, electricity.
2. Characteristics:
1) Compact continuous non-contact liquid level measurement.
2) Dimensional design, easy to install.
3) Over voltage and over current protection, lightning protection.
4) Large display window of LCD or LED, 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 a variety of working situations.
8) All-metal shell (IP67), sealed, alkali-resistant, meet the harsh
environment.
3. Measuring principle: Time-of-flight method
The liquid level meter is installed on the top of the container by
the ultrasonic probe and the electronic tube. Under the control of
the electronic device, the ultrasonic probe transmits the
ultrasonic pulse to the subject. Sound waves are reflected on the
surface of the object, and the detector receives partial echoes and
converts them into electrical signals
The signal instrument measures the time between the transmission
and reception of the pulse. time is proportional to the distance
from the probe to the object under test. 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.

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 |
