Pressure measurement
An IoT measuring system for water level or fill level monitoring and general pressure measurement
All the talk seems to suggest we are heading towards complete digitalisation. But how do you get on this path and what is the right direction for your own company? KELLER AG für Druckmesstechnik has over 45 years of experience in the area of recording and processing measurement data. Their service package ranging from pressure sensors to the finished web app helps you to find your own way to a customised IoT solution.
The intention and the need to make processes more efficient are at the heart of digitalisation. The path towards digitalisation begins with
I
recording data, mostly with sensors. Pressure sensors also record measured values. For machines or fill levels in containers and tanks, this takes the form of states. For lakes, rivers and groundwater, the levels are measured. The objects measured are connected to the Internet, save their data to a cloud and the data is mainly transmitted wirelessly via radio transmission. The latest technologies such as LoRaWAN or mobile communications (NB-IoT, LTE-M) are also used. The data can eventually be retrieved on all possible end devices such as computers, tablets or mobile phones. This entire Internet environment of and with objects is called the Internet of Things (IoT).
ndustry 4.0 and Smart City are technology drivers behind the digitalisation of pressure sensors and pressure measuring solutions.
A compREhEnsIvE IoT sERvIcE pAcKAGE KELLER AG für Druckmesstechnik offers this comprehensive solution, as described, of an IoT measuring system, based on the latest technologies. This type of measuring solution allows the user to take an immediate step towards digitalisation, without much effort and at low cost:
No software solutions or hardware need to be created.
A working and tested measurement data recording system can be accessed.
No separate, technically advanced training in the technologies is necessary.
KELLER’s measuring system is designed in such a way that each part of the measuring chain has a specific interface. Thanks to the open and well- documented cloud API (Application Programming Interface), the user can incorporate the measurement data processing system into their own information system and therefore start at exactly the point where the greatest benefits of digitalisation are revealed. KELLER makes available all individual interfaces 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, as required. How deeply this vertical integration is
implemented depends on the application and involves weighing the costs against the benefits. The lowest integration level is defining the pressure sensor signal. The following graph shows the individual integration levels from the pressure sensor series 9L up to the KOLIBRI Cloud web app:
