The water level measurement gauge features a wide voltage power supply, a wide measuring range coverage, and high-precision measurement, making it an ideal choice for various liquid level monitoring and control applications.
Industrial Liquid Level Adaptability
- The liquid level measurement range covers 0-50 meters, with selectable accuracy classes of ±0.5%FS or ±1%FS, meeting the needs of both large-scale water level monitoring and precise process control.
- Multiple output signal formats are available, including (4-20)mA, RS485 digital signals, adapting to the interface requirements of different industrial systems.
- Wide power supply voltage range, covering 9~30VDC, suitable for most industrial power supply environments.
Convenient Installation and Stable Measurement
- IP68 protection rating and features such as moisture resistance, leak-proofness, shock resistance, lightning protection, and electromagnetic interference resistance, enabling it to adapt to harsh working environments and ensuring stable equipment operation.
- Operating medium temperature range is -10℃～+70℃ (ensuring the medium does not freeze), and it is compatible with 304 stainless steel, suitable for long-term stable measurement of most common liquid media.
- Submersible installation with clear wiring rules and clearly defined wire colors, facilitating on-site installation and wiring.
Applications
The use scenarios of water level meters cover multiple fields such as industry, water conservancy, environmental protection, and energy. Its applications are diversified according to the characteristics of the measuring medium, environmental requirements, and functional requirements.

Q1: How to Read a Water Level Gauge Correctly?
A1: The key to reading a water level gauge correctly is to first check the device status and environmental conditions to ensure there are no interference factors, then use the corresponding method according to its type (such as glass tube, float type, pressure type or radar/ultrasonic) to read it, usually by looking directly or viewing the display, paying attention to the units and decimal points; at the same time, make sure the device is calibrated, and pay attention to factors such as bubbles and dirt that may affect the accuracy of the reading. Finally, record the reading and do daily cleaning and maintenance to ensure the reliability of the measurement results and the life of the equipment.
Q2: How to Calibrate a Water Level Meter?
A2: The water level meter calibration needs to be completed in a static water body. First, place the probe into a known depth (such as 0cm or standard water level) to adjust the zero point, then calibrate the range by comparing the actual water depth, and set compensation parameters according to the water temperature to eliminate thermal expansion and contraction errors. After completion, record the calibration data and recheck it regularly (such as monthly) to ensure measurement accuracy.
Q3: Common Operational Errors When Using Water Level Meters
A3: Common operational errors when using water level meters include improper installation, neglect of calibration, and neglect of environmental factors. For example, when installing the probe tilted or close to the inlet/outlet, the measured value may be too large or too small, or even fluctuate unstably; failure to perform zero point calibration or neglecting that the medium density does not match the device setting value may cause inaccurate readings.
Tips: What precautions should be taken when using a Water Level Meter in different scenarios?
- Groundwater Monitoring: Avoid installing the water level meter directly above the pumping pipe, otherwise the pump operation will cause continuous measurement noise.
- Sewage Tanks: Prioritize low-frequency ultrasonic models, as foam has a more significant impact on high-frequency ultrasonic waves.
- Open Channels/rivers: When used in conjunction with a flow meter, timestamps should be consistent to avoid data mismatch.
