▋ Product Size
▋ Measurement Method
BOY-WR04-C3 Submersible liquid level monitoring has the advantages of anti-interference, small temperature drift, high measurement accuracy, good stability and long life. Widely used in river, reservoir, groundwater, water supply and drainage, sewage treatment and other water level monitoring.
When the liquid level fluctuation is large, measures should be taken to fix the probe part of the liquid level gauge, you can insert or install a steel pipe or PVC pipe larger than the diameter of the probe in the water, and open a number of φ5mm holes in the pipe at different heights in the opposite direction of the water flow, so that water can enter the pipe.
▋ Application
▋ FAQ
1. Equipment measurement principle?
A: When the sensor is put into a certain depth of the measured liquid, the pressure of the measured medium is introduced into the positive pressure chamber of the sensor, and the atmospheric pressure on the liquid surface is connected to the negative pressure chamber of the sensor through the cable airway to offset the front of the sensor, so that the sensor can measure the pressure, and the liquid level depth can be obtained by measuring the pressure
2. What is the range of the equipment?
A: The default measuring range is 0 ~ 10 meters, and the larger measuring range needs to be customized.
3. What is the measuring accuracy of the equipment?
A: The measurement accuracy is not higher than 0.5%, such as 10 meters range, the accuracy is 5cm.
4. Can the equipment be waterproof? Will water flooding damage the equipment?
A: Can be waterproof, equipment IP68 protection level.
5. Device communication method? What communication protocols are supported?
A: Supports RS485 communication and Modbus communication.
