Product Overview: The Core Sensing Node of Digital Water Level
In water conservancy and hydropower projects, dam monitoring, and urban drainage systems, real-time monitoring of water level, seepage pressure, and pore water pressure is the key to evaluating structural safety. The Nexisense YD-211W/223WA1 series wireless water level gauge is an intelligent instrument integrating signal acquisition, data processing, and wireless transmission.
This product takes an advanced industrial-grade MCU as the core, and the acquisition front-end adopts a high-precision diffused silicon pressure chip, which can accurately sense changes in seepage pressure, uplift pressure, and pipeline pressure. Through Nexisense’s self-developed low-power management algorithm, the device can perform timed reporting or threshold-triggered reporting on demand, securely transmitting data to the cloud management platform, providing system integrators and engineering contractors with a high cost-effective and extremely easy-to-integrate automated monitoring closed-loop solution.
Technical Advantages: Deep Focus on Engineering-grade Reliability
Core sensing and material optimization
Nexisense selects high-stability diffused silicon sensors, with the pressure-sensitive diaphragm made of stainless steel 316L material. This material is not only corrosion-resistant but also has excellent mechanical strength, suitable for long-term immersion in various freshwater, seepage water, and pore water environments. Its structural design ensures that the main components can resist erosion by complex media.Multiple protection and anti-interference algorithms
Environmental adaptability: The device has excellent shock-proof and moisture-proof functions, fully adapting to extreme environments such as outdoor exposure or humid boreholes.
Algorithm compensation: For zero-point drift caused by temperature fluctuations, Nexisense adopts multi-point temperature compensation process to ensure consistent and accurate liquid level data output within the operating range of -20°C to 70°C.
Network robustness: Supports automatic network time calibration, automatic reconnection when disconnected, and local data caching function, ensuring that even when the base station fluctuates, historical data can be retransmitted without leaving monitoring blind spots.Ultra-fast deployment and intelligent interaction
Unlike traditional instruments, the Nexisense wireless water level gauge supports remote parameter setting sent by the server, eliminating the need for engineers to personally open the cover and debug on site. The body is equipped with a 42 × 30 mm ultra-large LCD display screen, making on-site status viewing clear at a glance.

Wiring and Installation Tips
Installation form: Nexisense adopts an integrated encapsulation structure. For deep hole monitoring, simply drop the sensor probe vertically to the bottom of the liquid level to be measured. It is recommended that the antenna end be exposed above ground or installed in a protective cover with good signal coverage.
Wiring definition: This device is a battery-powered wireless product, and the standard version requires no external wiring.
Operation and maintenance recommendations: Regularly check the 10-micron permeable bag at the top of the sensor. If the environment is extremely turbid, it is recommended to clean or replace the permeable bag every 6-12 months to ensure the dynamic response speed of the sensor.
FAQ: 8 Core Questions about Nexisense Wireless Water Level Gauge
Q1: What is the specific function of the 10-micron permeable bag?
A: It is equivalent to putting a “filter membrane” on the precision sensor. In borehole or river monitoring, if fine sand and gravel enter the sensor cavity, it may cause measurement lag or damage to the diaphragm. This filter membrane can block particles while ensuring accurate transmission of water pressure.
Q2: What to do if the 4G signal is very weak on site?
A: Nexisense supports antenna type selection and can flexibly select external gain antennas according to the site environment and lead them to a higher place with stronger signal.
Q3: Can the battery be replaced after it is used up?
A: Yes. The device is equipped with a standard 3.6V ultra-large capacity lithium battery. We recommend that professionals open the cover and replace it in a dry environment to ensure that the IP68 protection rating is not compromised.
Q4: How does the device achieve the “alarm” function?
A: Users can set upper and lower limit thresholds for water level or pressure through the backend platform. When the device senses abnormal pressure or low battery, it will immediately trigger the reporting mechanism.
Q5: Does it support docking with our existing monitoring platform?
A: Yes. The device adopts standard TCP/UDP communication protocol. Nexisense can provide open communication protocol documents to facilitate private deployment and docking by system integrators.
Q6: Can the data transmission frequency be changed?
A: Yes. You can modify it locally through button operation or remotely issue configuration instructions through the cloud server to adjust the acquisition interval and reporting frequency.
Q7: What are the advantages of diffused silicon sensors compared to ceramic capacitors?
A: Diffused silicon sensors have higher resolution and linearity when measuring small ranges and tiny pressure changes, and the overall volume is smaller, making them more suitable for deep well probe installation.
Q8: Does the device have lightning protection design?
A: Yes. As an industrial-grade instrument, the internal circuit of Nexisense integrates transient impact protection, combined with the IP68 housing, significantly improving the survival rate in outdoor thunderstorms.
