KLD102 Radar level meter and radar water level meter for measuring liquid level or distance with protection level IP67

80G FM Radar Level Meter

Principle:
The general principle of the FM continuous wave radar level gauge is that the radar emits electromagnetic waves on the top of the tank, and the electromagnetic waves are received by the radar after being reflected by the medium. The frequency difference δf between the received signal and the transmitted signal is proportional to the distance R from the surface of the medium: R=C (speed)*δf (frequency difference)/2/K (frequency modulation slope). Because the speed of light C and the frequency modulation slope K are known, the frequency difference δf can be estimated to obtain the distance R from the radar installation position to the material surface, and then through the known total height of the tank, subtract the spatial distance from the radar to the material surface (referred to as Empty height) to get the height of the material level.

Characteristic:
1. Millimeter-wave radar, with a measurement accuracy of up to ±1mm, and a minimum blind area of 0.1m.
2. The smaller antenna size satisfies the measurement of more working conditions.
3. A variety of lens antennas, smaller launch angle, more concentrated energy, stronger echo signal, under the same industrial and mining conditions, compared to other radar products have higher reliability.
4. With stronger penetrability, it can be used normally even if there is adhesion and condensation.
5. The dynamic signal range is larger, and the measurement of low dielectric constant medium is more stable.
6. A variety of measurement modes, the radar reaction time in the fast measurement mode is less than 1S.

Technical parameter

Communication and debugging
The instrument can be debugged through LDM in the field, and can also be debugged on the PC side with the optional host computer software. The connection between the meter and the PC is as follows:
to communicate with:
1. USB to RS485 serial cable (four-wire system);
2. USB to TTL serial cable (two-wire system);
3. USB to Hart-modem (two-wire system) for communication.
4. Through the mobile phone Bluetooth debugging, the on-site debugging is safer and more convenient.
5. 4G network, remote debugging through remote module.
