Smart tank monitoring: Radio signals into the cloud

With the new radio receiver LEVELview.WLAN from RCT, coded radio signals (868.45 Mhz) from the LEVELview transmission units can now easily be forwarded into the global network. This makes it possible to display all local information on fill levels of liquid gas tanks - as well as oil and water tanks - via the cloud-based information system of the RCT webapp on smartphones and PCs worldwide. Thanks to the LEVELview.WLAN, status notifications and alarms for the fill levels of up to twelve tanks can be sent quickly and free of charge online to the operator.


In the past, information about tank fill levels could only be read on an LCD display via radio signals in the immediate vicinity of the tanks or forwarded via data loggers as chargeable data SMS to the RCT online web application. With the new radio receiver LEVELview.WLAN, which can be easily connected to all standard routers, the remote monitoring specialist RCT Remote Control Technology from Bad Endbach has created completely new, convenient application possibilities for industrial and private users.


If an in-house WLAN is available, cyclical messages from tank radio transmitters can be forwarded via the LEVELview.WLAN to the RCT web application over the local network. Precise information on tank fill levels as well as temperatures, battery voltages and signal strengths of the transmitting units can be easily and automatically transferred to the RCT web server. Alarm notifications for set thresholds can also be forwarded either by email or push notification to the operator of the tanks.


The radio receiver WLAN consists of a total of three function modules: a WIFI module with integrated antenna and a 32-bit ARM CPU for autonomous editing of the necessary protocols and functions for connection via WIFI, an 868 MHz transmitter module with external antenna and a Power supply unit for connecting an operating voltage (9 ... 24 Volt).


The user-friendly menu control makes the LEVELview.WLAN easy to operate. Via four LEDs and the installation instructions in the user menu, the user learns how to set up the unit step by step. The radio receiver receives the data via the 868 MHz frequency from one or more (up to 12) transmission units. At set intervals, a corresponding code is sent to the receiver, which stores the cyclical data internally and sends it encrypted via the in-house WLAN at regular intervals to the RCT cloud storage. The data can then be called up and conveniently evaluated via the RCT web application (
