▋ Product Description
BOY-WR04-LR submersible liquid level monitoring device uses OEM pressure sensor with stainless steel isolation diaphragm as signal measurement element, and is automatically tested by computer. The zero point and sensitivity temperature compensation are carried out in a wide temperature range by laser resistance adjustment process. The amplifier circuit is located in the dry stainless steel housing and converts the sensor signal to the standard output signal. The submersible liquid level monitoring device 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.

▋ Measurement Method
BOY-WR04-LR submersible liquid level monitoring device 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.
▋ Installation Method
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
Applicable to: water plant, oil refinery, chemical plant, sewage treatment plant, high-rise water supply system for water supply pool, distribution pool, water treatment pool, municipal rain sewage well, water tank, water tank, oil tank, oil tank and other liquid static and dynamic level measurement.
▋ 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.
