Customer demand:
Nigerian customer needs to monitor the water level and temperature of a deep well with a depth of 200 meters and a well diameter of 150mm. The data must be accurate and reliable, and both local data reading and remote monitoring must be achieved to reduce the risk of manual intervention.
Solution core components:
1. PWP412-W submersible pressure level transmitter for deep well
Synchronous measurement: water level (0-200 meters) and water temperature (-40℃ to +80℃)
Output signal: dual independent 4-20mA (one for water level/temperature)
Accuracy level: water level ±0.5%FS, temperature ±1%FS
Special cable: 200 meters steel reinforced PUR cable (tensile and wear-resistant)
Well diameter adaptation: choices of probe diameter 27mm, 19mm and 16mm compatible with narrow well
2. P5200 field display + Audible&visual alarm
Real-time reading of water level and temperature data on site, with adubile&visual alarm
3. PW302 wireless module + IoT monitoring platform
Transmit data to cloud platform via 4G/IoT
Remotely view real-time data on web/mobile terminal
Set water level/temperature alarm threshold
Automatically generate historical data trend chart
Solution advantage analysis:
Challenge | Disadvantages of traditional solutions | This solution measures |
200m deep well monitoring | Large signal attenuation | 4-20mA signal anti-interference transmission |
150mm narrow well diameter | Difficult equipment installation | Compact sensor design (diameter <27mm) |
Dual parameter precise monitoring | Multiple equipment conflicts | Single sensor integrated water level and temperature synchronous measurement |
Remote data acquisition | Rely on manual downhole meter reading | Real-time wireless transmission on IoT platform |
Implementation results:
1. Data accuracy
Water level sensor with 0.5% accuracy
Temperature monitoring accuracy is ±1℃ (80℃ range)
2. Operation and maintenance efficiency
Cancel manual well inspections to reduce safety risks
Instant response to abnormal water levels through platform alarms (such as SMS notifications)
3. Decision support
Historical data trend analysis to optimize water intake scheduling
Reduce equipment idling losses caused by monitoring blind spots
Conclusion:
This solution uses the PWP412-W water level sensor with 0-200m range to accurately collect deep well data and combines it with the IoT platform to achieve remote monitoring, solving the accuracy and operation and maintenance problems of water level/temperature monitoring in a narrow deep well environment for Nigerian customers. The armored cable ensures reliable transmission at a depth of 200 meters, and the dual-parameter integrated design avoids conflicts among multiple devices, ultimately achieving the dual goals of "accurate monitoring" and "worry-free operation and maintenance".
