The working principle of the laser aluminum water level meter is to use the reflection time of the laser beam to measure the height of the liquid from the sensor to obtain liquid level information. It uses the phase comparison principle for measurement, emits visible laser beams of different frequencies through a laser sensor, and receives the scattered laser light returned from the object being measured. The received laser signal is compared with the reference signal, and finally the microprocessor calculates the distance between objects corresponding to the corresponding offset to achieve accurate liquid level measurement. Its accuracy can reach millimeter level, and it is a high-precision and high-reliability measuring equipment.
