In today's era of rapid technological development, accurate and real-time level and flow data serve as the cornerstone for ensuring production safety and optimizing resource scheduling. Traditional measurement equipment often faces challenges such as high maintenance costs and poor data continuity when dealing with sediment accumulation, corrosive media, and complex geographical environments.
With its technical advantages in the sensor field, the NiuBoL brand is gradually becoming a mainstay in the level monitoring industry. By integrating high-precision sensing with wireless communication technology, NiuBoL achieves remote monitoring and intelligent management of level data, assisting the water conservancy, municipal, and industrial sectors in advancing toward intelligent development.

1. Submersible Measurement: Hydrostatic Physical Modeling
NiuBoL submersible level meter is based on the principle of fluid statics, using a high-sensitivity diffused silicon chip to convert liquid pressure into height data.
2. 77GHz Radar Flow Measurement: A Non-Contact Revolution
For open channels and rivers, NiuBoL adopts 77GHz~79GHz Frequency Modulated Continuous Wave (FMCW) technology. Its narrow beam angle (8°) design effectively filters false echoes, achieving millimeter-level perception of water level and flow velocity, and automatically converts real-time flow through flow model formulas.
3. Wireless Communication and Low-Power Architecture
The device integrates 4G / NB-IoT communication modules, supporting dual-mode power supply with conventional power and built-in lithium battery. The low-power design ensures several years of endurance in remote areas, with simple and convenient battery replacement later.
Industrial-Grade Protection: The head adopts die-cast aluminum alloy shell with epoxy spraying, and the transmitter end reaches IP68 rating. High-quality TPU vented cable is acid-alkali resistant and tensile resistant, safe for long-term immersion.
Data Security Barrier: Built-in 120,000 offline storage records function. Automatically saves data during signal interruption and ensures data chain integrity through “breakpoint resume transmission” after reconnection.
Temperature Automatic Compensation: Features automatic temperature drift correction function, eliminating the impact of seasonal temperature differences (-40℃~+80℃) on measurement accuracy.
Core Correction Algorithm: Adopts self-developed algorithm to effectively suppress numerical fluctuations caused by water surface waves or pump start/stop, ensuring stable output.

1. Firefighting Rescue and Urban Water Supply
Firefighting water trucks: Real-time monitoring of tank level, uploading signals to the cloud to assist precise dispatch of rescue water sources.
Secondary water supply: Deployed in high-rise pools, wells, and water towers to promptly detect abnormal water levels and ensure continuous residential water supply.
2. Water Treatment and Environmental Protection
Water plants / sewage treatment plants: Real-time monitoring of chemical dosing tanks and sedimentation tanks. Stainless steel isolation and anti-corrosion design resists medium erosion, ensuring stable production processes.
Water cycle monitoring: Provides data support for optimizing treatment processes and achieving intelligent management.
3. Complex Geology and Extreme Environments
Mines / geothermal wells: In high-temperature, high-pressure, and deep well environments, NiuBoL achieves precise level control with multiple protective structures and strong anti-interference capabilities.
Ocean / reservoir monitoring: Copes with surging waves or sediment accumulation. The sloped guide hole design effectively prevents impurity entry, with excellent impact resistance.

To ensure long-term precise operation of NiuBoL equipment, please refer to the following practical recommendations:
Still Water Protection: In rivers with fast flow or stirred pools, install protective sleeves or use damping structures to reduce direct impact of hydrodynamic pressure on the diaphragm.
Vent Balance: The vent tube at the end of the vented cable must not be bent or sealed. Keep the junction box dry and use the vent tube to offset errors caused by atmospheric pressure fluctuations.
Anti-Silt Blockage: Utilize the device's built-in sloped guide hole design. During installation, keep 5-10cm away from the silt layer to effectively prevent impurity accumulation.

Q1: What to do if the wireless level transmitter has poor signal in an underground metal well room?
A: NiuBoL supports an external antenna extension solution. By routing the suction cup antenna to the wellhead surface or vent, it can perfectly bypass electromagnetic shielding and ensure smooth 4G data upload.
Q2: How to cope with drastic atmospheric pressure changes during typhoons or thunderstorm seasons?
A: NiuBoL uses a dedicated shielded vented cable. The vent tube introduces external atmospheric pressure in real time to the sensor back pressure side, physically canceling measurement deviations caused by atmospheric pressure fluctuations, ensuring water level readings always represent the true liquid surface.
Q3: What is the practical use of 120,000 offline storage records?
A: This is crucial for remote areas or during base station maintenance periods. Even if the network is interrupted for several days, the device still locally saves every sampling point and automatically re-uploads after reconnection, ensuring continuity of hydrological historical reports.
Q4: How is the equipment lifespan in corrosive media?
A: The equipment uses 316L stainless steel shell and TPU cable. It has excellent corrosion resistance against domestic sewage, general industrial wastewater, and oils. For strong acids and alkalis, consult us for fully fluorinated material customized versions.

In summary, the NiuBoL wireless level transmitter, with its wide range of application scenarios, hardcore protective performance, and forward-looking IoT technology, is gradually becoming a leader in the level monitoring field. It not only solves measurement challenges in firefighting, municipal, and industrial sectors but also assists management decisions through cloud data analysis.
As technology continues to advance, NiuBoL will keep deepening its efforts in the perception layer, providing global users with more convenient, efficient, and secure level measurement solutions. Do you need customized solutions for deep wells, firefighting linkage, or industrial drainage?
