Product Details

Battery-Operated Level Sensor With 4G Communication and Free Web Portal for Heating Oil Tanks, Cisterns, Storage Tanks

The Proteus EcoCloud 4G is an innovative, universal, battery-operated ultrasonic level gauge with 4G module for the measurement of fuel oil tanks, cisterns and storage tanks. The Proteus EcoCloud 4G measures the contents of your tank up to 4 times an hour and transmits measurement data via the 4G network to a data server at least once a day. This data is then displayed on a web portal (web app) also optimized for display on mobile devices such as smartphones. The web portal shows you the current daily filling level, the actual volume (in percent and liters), the battery level and the signal strength of the mobile network. It also generates a graphical representation of the level curve which consists of the previous daily measurement data.

The installation is very easy and takes only a few minutes. Cabling is not necessary as the ultrasonic sensor is battery operated.

The EcoCloud 4G is a modern and precise alternative to mechanical dipsticks, tank gauges or analogue systems and can be used especially in areas with no connection to the mains. The system saves several control rounds in cellar to check your cistern and avoid empty tanks. The EcoCloud reads off the consumption and compares in time e.g. prices for fuel oil to prepare for re-ordering.

Easy to install and compatible with 1 1/4″, 1 1/2″ and 2″ thread openings, the EcoCloud 4G is universally applicable for tanks with liquids as long as a 4G mobile connection is available. The required SIM card is included free of charge and will be configured and delivered by our customer service with your tank data - this makes the installation extremely easy, you only have to mount the device on the tank.
