IoT sewerage water sensor & monitoring system

Sensor system to Monitor (waste) water infrastructure

The Smart Cities water sensor platform is an entire solution for obtaining relevant information about waste water and/or a complete sewerage network. The sensing platform can also be used for surface water measurement applications.

Accurate, real-time data

In order for municipalities and water authorities to proactively manage their networks they need data; they need real-time data; and they need the correct real-time data.

Predictive analytics

In addition, they need the tools and technology to correctly analyze, synthesize and process this data to make adjustments capacity utilization as well as and to optimize maintenance and servicing. Predictive analytics.

2M develops, together with a number of partners a smart system for the measurement and analysis of various wastewater parameters. The aim is to create a low cost system to cleverly control wastewater and the infrastructure of the sewerage system.

Product Brochure WS100 – waste water sensor

Low cost IoT sewerage water sensor

An easy to install sensor is placed within the sewerage pipe that communicates to the outside world using LORA, RS485, BLE or other technology without damaging the pipe. The whole system can be battery powered or solar powered. When such sensors are placed at various key locations in the network and centrally analyzed powerful metrics can be extracted that gives insights not possible today.

Key features

Accurate measurement of physical waste water parameters

The WS-100 measures water level, water pressure, water flow and water temperature in high-resolution. The thickness of the silt layer can also be measured.

Measurement of other parameters (optional)

The WS-100 can be extended with additional measurement parameters, for example sensors to measure conductivity and pH for specific applications.

Local data storage

The WS-100 locally stores raw measurement data ensuring long, completely standalone unattended operation. Having access to raw measurement data is perfect for research applications and/or for developing AI based decision making processes.

Rugged & waterproof

The WS-100 is fully waterproof (> IP69) and built to last. Sensors are not affected by pollution in their operating environ- ment. Enclosures are made of tough materials that also protect the electronics well.

Easy to maintain

Sensors and system require very little to no maintenance. Power banks can be charged on location. The system keep detailed error logs to quickly find potential problems.

Connectivity

Standard communication via RS485/Modbus or BLE. Other standards or optical communication can be made available on request.

Application Programming Interface

The complete API is available to communicate over RS485 or wireless BLE. The API and internal data processing can be customised for specific applications.

OEM customizations

The WS-100 water measurement platform can be customised or extended for specific applications.

Data platform & analysis

Data platform with multi-dimensional analysis giving deep insights in nature, origin and pollution degree over time across a complete city.

Ultrasonic sensing

Ultrasonic sensing uses the time of flight (TOF) of an ultrasonic wave and its dependency on the flow rate of the medium to measure and calculate volume flow, using the difference in the propagation time of the ultrasonic wave when transmitted into and against the direction of the flow. This technology is outstanding at measuring volume flow rates across a wide range and works with fluids like water and oil as well as gases like air and methane.

Benefits

  • Long life time 20 years
  • No moving parts
  • Low minimum flow rate Qmin at 5 – 10 L/hr
  • Can detect small flow leakage ( ~1L/hr )
  • High accuracy
  • Re-calibration >20 years
  • No tampering issue
  • Electronic device to enable AMR

Rioned innovatie prijs 2019

IoT waste water sensor system

Feb 2019

As mentioned earlier, we are nominated for the Rioned Innovation Prize 2019. Rioned had selected 4 projects out of 12 entries. A great opportunity to show this project to a wider audience. In preparation for this we made a nice animation film in which we can see how we started this project, what we have already achieved together with our partners and where we eventually want to go.  We proudly showed this film after which the audience could ask questions. The result is great. The film was received enthusiastically and people were very interested in the sequel. Of course we are happy with our 3rd prize and that we could use this stage.

Via deze link https://youtu.be/OkZqWORfecQkan je de film  bekijken.

Project Status

Pilot production. We are soon delivering a number of systems for long term stability measurements. Date: 30-06-2021

Two systems have been installed: one in the city of Breda and one in Roosendaal. The systems are operational and the first data is appearing. Date: 8-02-2019

A first proof of concept has been created that fits in the water sewerage test setup in Breda. The sensor electronics and sensorring fits in a pipe with 300mm diameter. First measurements have been planned. The sensor measures at fixed intervals and sends it to a central point using a LoRa radio module. The sensors measure water height, waterspeed and water temperature in the pipe. The sensorring is completely created using printed electronics sensorfoil. Date:07-03-2018

Funding

This project was made possible by a contribution from the European Regional Development Fund as part of OP-Zuid.
