Customised IoT pressure management solutions

Efficient processes are at the heart of digitalisation. With close to five decades of recording and processing measurement data, Keller offers a range of solutions – from pressure sensors to the finished web app.

The path towards digitalisation begins with recording data, mostly with sensors. In addition to other values, pressure sensors can record the levels of lakes, rivers, groundwater, drinking water storage in JoJo tanks (game reserves) and pressure drops in pipes (non-revenue water). This data is mainly transmitted wirelessly via radio transmission, using technologies such as LoRaWAN or mobile communications (NB-IoT, LTE-M), and then saved to the cloud. It can then be retrieved on all possible end devices such as computers, tablets or mobile phones.

IoT service package

The internet of things (IoT) describes physical objects with sensors that connect and exchange data with other devices and systems over the internet or other communications networks. Keller offers a comprehensive IoT measuring system that allows the user to take an immediate step towards digitalisation, without much effort and at a low cost, where: • no software solution or hardware needs to be created • a working and tested measurement data recording system can be accessed • separate, technically advanced training is necessary. Keller’s measuring system is designed so that each part of the measuring chain has a specific interface. The user can incorporate the measurement data processing system into their own information system due to an open cloud application programming interface (API). All individual interfaces are available, so that users have free choice, in terms of implementation, as to whether they would like to set up the entire system or only parts of it.

Individual integration levels from the pressure sensor series 9L up to the KOLIBRI Cloud web app

The extent to which vertical integration is implemented depends on the application and involves weighing the costs against the benefits Keller comprehensive IoT service package

The sensor that records the data is one of the most important parts of the IoT system because decisions are made and actions taken based on its measurements

Step by step approach to digitalisation

Specify data recording points/ measuring points. Define a suitable pressure or level sensor based on requirements such as accuracy, compatibility of media. Select transmission technology by assessing available network coverage at measuring point. The measuring points selected should be as close as possible to the person responsible for the system so the discrepancy can be found and remedied in the event of a fault on-site. Verification of the measured values recorded should also be performed during operation at the measuring location. Operate measuring points with the help of a graphical representation in a cloud for a few weeks and monitor closely. Expand the measuring system (POC) with additional, possibly technically critical measuring points and close monitoring of any discrepancies. Up to step 5, the IoT Keller measuring system is used with little investment. It must now be assessed whether the system is to be kept as it is, or whether a deeper integration of the system into the company’s software is desired. Automatic data synchronisation between the measuring system and the company’s own cloud. Many service providers do not know the process of generating IoT measurement data. Keller can assist in establishing clear and concrete functional requirements for the measurement data it records in an external system. Complete vertical integration.
