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.

Basic data
| Type | MLT |
| Power supply | DC24V (±10%) 60mA |
| Display | 4 digit LCD |
| Accuracy | 0.2% of full span (in air) |
| 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 |
| Protect grade | IP67 |
| Fix | Screw or Flange |
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.
| MODEL | MLT4 | MLT6 | MLT8 | MLT12 | MLT15 | MLT20 | MLT30 |
Blacking distance | 0.20m | 0.25m | 0.30m | 0.45m | 0.60m | 0.80m | 1.20m |
