Ultrasonic Liquid Level Meter 0-40M With Output 4-20mA / 1-5V / RS485
1. 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.
2. Characteristics
1) Compact continuous non-contact liquid level measurement;
2) Body design, easy installation;
3) Over-voltage, over-current protection, lightning protection;
4) LCD or LED large display window, easy to debug and observe;
5) Anti-interference ability;
6) 4-20mA output;
7) Intelligent signal processing technology to ensure that the instrument meets all kinds of workplace
8) All metal case (IP67), sealed, alkali resistant, meet harsh environment.
3. Technical data:
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.
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 |
4. Advantages And Disadvantages
There are some advantages of ultrasonic level measurement which are given below
- The ultrasonic level measurement is suitable for measurement in liquid and solid.
- It is simple in construction and design.
- It does not require contact with processed material.
- It provides continuous level measurement.
- It has high accuracy.
- The sensitivity is high.
There are some disadvantages of ultrasonic level measurement which are given below
- The ultrasonic level measurement is comparatively expensive.
- If heavy foam is present on the surface it acts as an absorbent which creates errors.
- Targets of low density, like foam and cloth, tend to absorb sound energy; these materials may be difficult to sense at long range.
