Product Description
Ultrasonic Type Working Principle Level Measurement Ultrasonic Level Sensor
Product Description
The series is an compact 2-wire series ultrasonic level meter for continuous non-contact level measurement in liquids and solids. It consists of probe and electronic units, both of which are leak-proof structure. This series can be widely applied to the metallurgical, chemical, electricity and oil industries.
Features
Continuous non-contact level measurement with compact version;
- Integrated design, installed conveniently;
- Protected in the excessive voltage and current , protected in the thunder and lightning;
- The big show window of LCD or LED is easy to debug and observe;
- Excellent anti-interference capability;
- 4-20mA output;
- Intellectual signal treatment technology, guarantee that the instrument meets various kinds of operating occasion
- All metal outer cover ( IP67 ), airproof and alkali-resisting, meet the abominable environment.
Structure & Material
The series is consists of sensor and electronic unit.
Working Principle
The sensor of the meter pulses in the direction of the product surface. There, they are reflected back and received by the sensor. The meter measures the time t between pulse transmission and reception. The meter uses the time t (and the velocity of sound c) to calculate the distance D between the sensor membrane and the product surface: D = c •t/2 . As the device knows the empty distance H from a user entry, it can calculate the level as follows: L = H - D .
An integrated temperature sensor compensates for changes in the velocity of sound caused by temperature changes. Calibration Enter the empty distance H and the span F to calibrate the device.
Blanking distance : Span F may not extend into the blanking distance B. Level echo from the blanking distance cannot be evaluated due to the transient characteristics of the sensor. Product Parameters

2.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 | 15.00m |
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.3.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 |
