Modbus Output
1. Application:
This series is an integrated two-wire ultrasonic liquid level meter
continuous non-contact liquid level measurement of liquid and
solid. It consists 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.
chemical, electricity.
2. Features:
1) Compact continuous non-contact liquid level measurement;
2) Body design, convenient installation;
3) Over voltage and over current protection, lightning protection;
4) LCD or LED large display window, 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 all kinds of workplaces
8) Full Metal Jacket (IP67), sealed, alkali-resistant, meeting the
harsh environment.
3. Measuring principle: Time-of-flight method
Level meter consists of an ultrasonic probe and an electronic
unit.Level meter is mounted on top of the container,under the
control of the electronic unit, the ultrasonic probe transmitting
ultrasonic pulses to the measured object.Sound waves are reflected
by the surface of the object, part of the echo received by the
probe and converted to electrical
signals.The meter measures the time between pulse transmission and
reception. The time is proportional to the distance from the probe
to the measured object. The electronic unit detects this time and
calculates the measured distance based on the known sound velocity.
Level value can be obtained by the subtraction.
H: installation height
D: distance value
L: level value
B: blacking distance
F: full scale

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 |
