Its corrosion-resistant probe design and optional high-precision versions can meet the needs of corrosive media or precise process control, ensuring stable process parameters.
In environmental and hydrological monitoring projects, this transmitter is widely used for long-term monitoring of rivers, lakes, reservoirs, and groundwater wells. The wide-area coverage characteristics of NB-IoT enable stable operation in remote areas with inconvenient power supply or difficult wiring, providing data support for water resource assessment, flood warning, and ecological monitoring.
In addition, in scenarios such as industrial cooling circulation systems, fire water tanks, mine drainage, and large agricultural irrigation water towers, YD-221W3 helps achieve unattended monitoring, significantly reducing on-site inspection costs and improving overall system operation and maintenance efficiency. Many system integrators have successfully applied this series of products in smart water platforms and environmental monitoring systems, achieving multi-point data aggregation and visual analysis.
Selection Guide
To match specific project working conditions, it is recommended to select from the following dimensions:
Range determination: Select the standard range according to the maximum liquid level height on site and reserve 20%-30% margin to cope with fluctuations. Non-standard ranges can be responded to quickly through customization.
Precision matching: For conventional monitoring, 0.5% accuracy is recommended; for occasions involving measurement settlement or high-precision control, priority should be given to customized 0.1% or 0.25% versions.
Medium compatibility: Evaluate liquid corrosiveness, temperature range, viscosity, and impurities, and select appropriate probe material and sealing design.
Communication and power configuration: Confirm NB-IoT network coverage; battery-powered models are suitable for environments without power supply; when external power is selected, power stability must be ensured.
Installation interface and environmental adaptation: Select thread specifications according to the on-site mechanical interface, consider explosion-proof, lightning protection, and vibration conditions, and choose corresponding protection configurations.
Before purchase, provide detailed working condition parameters (medium type, temperature, installation location, integration system, etc.), and the technical team can provide targeted configuration suggestions.
Integration Precautions and System Compatibility
YD-221W3 focuses on engineering integration convenience and supports mainstream IoT platforms and industrial automation systems.
Communication Integration: The NB-IoT module adopts standard protocols and can directly access operator networks or enterprise private clouds. Data format supports JSON, etc., facilitating connection with PLC, DCS, or host computer software via API or gateways.
Power Management: Battery-powered products need reasonable planning of acquisition and reporting intervals to avoid frequent communication shortening endurance. In complex environments, large-capacity battery packs or external power modules can be paired.
Installation Key Points: The probe should be placed vertically in the medium, avoiding strong turbulence areas or near water inlets/outlets. The fixing bracket must be stable, and the vented cable should be laid to prevent bending, pulling, or long-term immersion damage.
Debugging and Reliability: Use supporting tools to complete range mapping, alarm threshold, and reporting cycle settings. On-site testing must verify data accuracy, transmission stability, and retransmission function after network recovery. It is recommended to configure system-level redundancy mechanisms and data encryption to improve overall security.
In terms of electromagnetic compatibility, the installation location should avoid strong interference sources. If necessary, edge gateways can be combined to achieve multi-device networking and protocol conversion.
