With the continuous progress of science and technology, radar water level meter is being used more and more.
It has the advantages of low cost, high stability, flexibility and reliability, low power consumption, convenient parameter setting, easy maintenance safety, etc. It has important promotion value.
Today I will take you to briefly understand the radar water level meter.
Radar water level meter is measurement equipment introduced from abroad in recent years, the water level meter technology is mature, has high measurement accuracy, is easy to install, and is not subject to environmental and geographical restrictions, so it has been widely used.
The radar water level meter antenna transmits a very narrow microwave pulse, this pulse propagates in space at the speed of light and encounters the surface of the measured medium, part of its energy is reflected back and is received by the same antenna.
The time interval between the emitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium. Due to the extremely high speed of electromagnetic wave propagation, the time interval between the emitted and received pulses is very small (in the nanosecond range) and difficult to confirm.
①Small beam angle, concentrated energy, stronger anti-jamming capability, greatly improving measurement accuracy and reliability
②Small antenna size, easy to install and add dust cover and other antenna protection devices
③Lighter weight of about 1KG, easy to install
④Measuring range up to 30m, covering small and medium-sized reservoirs and other water level measurements
⑤Multiple output circuit interfaces with the acquisition system
⑥Pulse mode of operation, the radar water level meter emits very low power, which is harmless to the human body and the environment.
The installation of the radar water level meter must remain vertical with the measured object; there must not be any obstruction between the measured object and the radar water level meter, otherwise,
it will affect the reflection of the radar wave, i.e. affect the measurement accuracy; the distance between the center of the radar water level meter and the bank of the water body must be greater than the radius of the emitted beam,
otherwise, it will also affect the measurement accuracy; the cantilever bracket for the installation of the radar water level meter must be firm and cannot be shaken up and down; in order to protect the radar water level meter,
can be installed in the cantilever bracket water level meter position fixed a small iron box, the radar water level meter probe put.
