Level is, along with temperature and pressure, an extremely common measurement in all environments.
Level can be measured using different types of sensors depending on the application, but perhaps the most common level sensor is a pressure sensor immersed in the media or mounted in the bottom of the vessel.
Ground and surface water
In these applications, more or less only immersible pressure sensors are used. These measure absolute or relative pressure in the water, and after recalculation level is often presented in meters above sea level.
Groundwater measurements are normally made in groundwater pipes and wells, and their small diameter means that sensor dimensions are important. Of similar consequence is that connection cables are adapted to the measuring depth.
Surface water is generally measured less deep but higher demands are made on mechanical stability and tolerance to mechanical impact and freezing. We deliver sensors from the market’s leading suppliers and can select the best solution for the application.
Even in tanks and cisterns, immersible or bottom-mounted pressure sensors can be used. However the properties of the media require other types of sensors such as ultrasound, radar or capacitive sensors. We work with various suppliers and can even arrange installation and start-up of the system.
