Pressure management in pipe networks is fundamental to providing safe drinking water. ThingsLog has developed a simple and cost-effective technology to continuously monitor pressure in potable and heating water distribution systems.
The solution could be delivered in a low power mode for locations where there is no power supply or in high frequency mode in case power supply or solar is possible.
How does it work?
The solution is based on ThingsLog low power data loggers with 2G, NB-IoT network connectivity. Either logger has CE certification and has IP68 International Protection Marking.
To either of the loggers could be attached up to two pressure sensors on an analog current ports (4-20mA). In addition to that to the logger could be attached also up to two water meters or other flow sensors.
The Pressure sensors that we use have IP68 and are suitable for precise pressure monitoring – the solution is based on various submersible pressure sensors and allows precise pressure monitoring through the analog current (4-20mA) port inputs of the data loggers. In the backend you can define a formula converting the mA to bars or psi and then convert those metrics to level or volume.
In case the solution is delivered in a low power mode the loggers will wake on defined interval of time will provide power to the pressure sensors, will wait for certain amount of sensor setting time and will measure the value.
If a real time pressure sensor monitoring frequency is required on 1s, 10s or even sub second the loggers will need 12 or 24V power supply. The solution could be delivered also on solar in case putting a solar panel close to the sensor is possible.
The sensor readings will be stored into the internal memory of the logger and will be transmitted to the ThingsLog platform on a configurable interval of time. The platform will store the values, will analyze them and will trigger a notification if certain threshold is bridged. If remote integration is required ThingsLog could send the sensor readings over a standard http/https integration to a 3th party platform. Anything that the platform is using is exposed over a convenient REST API.
Pressure management in pipe networks are fundamental to providing safe drinking water or quality public heating service. The loss of pressure can allow ground water to contaminate the distribution system. Fluctuations in pressure can affect the physical integrity of pipes. Surges in pressure have been known to create additional leaks, main breaks and/or dramatically reduce infrastructure life. Smart pressure management can also save money. Accurate pressure data allows system operators to reduce leakage volumes, energy costs, system maintenance costs, customer complaints, and water quality problems.
The solution is suitable for water and heating utility companies, for system integrators that would like to offer pressure monitoring but also for customers that would like to monitor the pressure levels of the water delivered to them by the utilities.
- Reduce unaccounted for (non-revenue) water (NRW)
- Identify potential infrastructure failures related to pressure fluctuations which can lead to significant repair costs.
- Reduce pumping and energy costs
- Improve public safety
