In the vast field of level measurement and control, data accuracy and equipment stability are the cornerstones of industrial production and municipal management. Traditional measurement methods often face pain points such as high failure rates and large data deviations when dealing with sediment, corrosive liquids, or deep well environments.
The NiuBoL submersible level meter (submersible level transmitter), with its excellent hydrostatic measurement performance and extremely strong scenario adaptability, has become a leader in the industry. It not only achieves precise capture at the physical level but also provides comprehensive smart monitoring assurance for water plants, mines, and industrial storage tanks through IoT technology.

1. Hydrostatic Principle and Diffused Silicon Core
NiuBoL submersible level meter is based on the physical characteristic that level depth is proportional to hydrostatic pressure.
Imported diffused silicon chip: Uses imported diffused silicon pressure-sensitive unit, combined with low-power ADI professional chip, to linearly convert liquid pressure into electrical signals.
Microsecond-level response: Sampling time up to 2400 times/s, ensuring keen perception of instantaneous level changes.
2. Core Automatic Correction Algorithm
For outdoor reservoirs, rivers, or industrial pools with stirring devices, water surface fluctuations are the main cause of errors. NiuBoL has a built-in core automatic correction algorithm that intelligently identifies and filters numerical jumps caused by surges or vibrations, ensuring smooth and authentic output data.
3. Multiple Protection Structure Design
Front protective cap: Protects the fragile sensor diaphragm while allowing smooth liquid contact through flow guidance design.
Sloped guide hole: Unique design effectively prevents silt and impurities from entering the cavity while significantly enhancing the sensor's resistance to water flow impact.
Triple protection: Features reverse polarity protection, instantaneous overcurrent, and overvoltage protection, fully complying with EMI protection requirements.

NiuBoL submersible level meter integrates 4G / NB-IoT communication modes, supporting real-time upload of data to the environmental monitoring cloud platform.
Remote control: Managers can set level upper/lower limit reminder values on mobile or PC terminals. Once the level exceeds limits, the system immediately triggers over-limit reminders.
Data breakpoint resume transmission: Features automatic storage function. Even if the network is temporarily interrupted, monitoring data is temporarily stored locally and automatically supplemented after reconnection, ensuring continuity of historical curves.
The device supports 10-30V DC wide voltage power supply, while featuring a built-in high-energy lithium sub-battery:
Ultra-long endurance: Relying on low-power design, battery life can reach up to 5 years under standard acquisition frequency, greatly reducing maintenance frequency in remote areas.
The device head comes with a large-size LCD screen, allowing on-site inspection personnel to view in real time:

1. Municipal Water Supply and Sewage Treatment
In water plants, high-rise water tanks, and sewage treatment pools, level fluctuations directly relate to water supply safety and pump lifespan. NiuBoL's anti-corrosion isolation design and IP68 protection rating ensure robust performance even in harsh water quality.
2. Deep Wells, Mines, and Geothermal Monitoring
Underground environments are complex and variable. NiuBoL submersible level transmitter features temperature automatic compensation and temperature drift automatic correction functions, eliminating measurement errors caused by geothermal or mine temperature differences, providing reliable data for geological and hydrological research.
3. Industrial Oil Tanks and Petroleum Management
For non-strongly corrosive industrial oil tanks, stainless steel material and fully sealed structure ensure measurement safety and stability.
4. River, Reservoir, and Ocean Monitoring
The sloped guide hole effectively prevents sediment accumulation. Combined with big data analysis on the cloud platform, it can monitor watershed levels in real time and play a key early warning role in flood prevention and disaster reduction.
Still Water Zone Selection: In environments with fast flow velocity, it is recommended to install protective sleeves or use damping tubes to avoid dynamic pressure impact on accuracy caused by water flow.
Vent Tube Protection: The vent tube inside the cable must not be kinked or blocked. The wiring end should be in a dry and ventilated place to ensure accurate atmospheric pressure compensation.
Anti-Condensation Design: NiuBoL's internal structure includes anti-condensation design, but in extremely humid environments, it is recommended to check the wiring end sealing to ensure long-term operation.

Q1: How to understand the significance of “automatic temperature compensation” for accuracy?
A: Pressure sensors are extremely sensitive to temperature. NiuBoL uses a built-in temperature sensing unit and algorithm to compensate for thermal expansion and contraction effects at the physical level. This ensures that level readings remain consistent without temperature drift offset in northern severe winters or southern scorching summers.
Q2: What to do if the monitoring point is in a basement with extremely poor signal?
A: The device supports 4G/NB-IoT high-penetration signal protocols. In fully shielded environments, RS485 wired signal can be routed to the surface, with transmission distances up to 2000 meters.
Q3: What makes the high-quality TPU vented cable different from ordinary cables?
A: TPU cable has extremely strong chemical corrosion resistance and mechanical strength. More importantly, it integrates a dedicated vent tube inside, which can transmit external atmospheric pressure in real time to the back pressure side of the sensor diaphragm, thereby automatically canceling reading deviations caused by atmospheric pressure fluctuations.
Q4: Why is a sampling frequency of 2400 times/s so important?
A: High-frequency sampling, combined with the core automatic correction algorithm, can capture and eliminate random water wave interference, outputting an extremely smooth and precise level value through digital filtering technology.
Q5: When the NiuBoL submersible level transmitter measures liquids with higher density (such as crude oil or concentrated liquids), does the data need calibration?
A: Yes. The working principle of the submersible level meter is pressure conversion (P=ρ*g*h). NiuBoL is factory-calibrated by default using clean water density (ρ=1000kg/m³). If your measured medium is crude oil, chemical concentrate, or highly saline seawater, its density differs from clean water. You can input the actual medium density correction coefficient through our supporting LCD screen buttons or cloud platform remote management function. The device's internal microprocessor will then automatically perform linear conversion to ensure the output level value is the true depth for that specific medium.

NiuBoL submersible level meter, with its precise diffused silicon core, hardcore IP68 protection, and intelligent wireless transmission functions, is reshaping the industry standard for level monitoring. It not only reduces users' initial installation and later maintenance costs but also enhances the automation level of safe production through cloud linkage. In the wave of smart management and Industry 4.0, choosing NiuBoL means choosing stability, reliability, and digital empowerment.
