level meter with differential pressure sensor up to 4m

picture of level meter board with differential pressure sensor
The level meter electronic board was designed for measuring fluid levels within opened or closed tanks. The electronic uses therefore a differential pressure sensor, that is able to measure levels of up to 4m and transmit those values to a master periphery (datalogger) or to a PC via RS485 interface. Additionally the temperature of the ambient or the fluid is also measured. It is only necessary to plug a hose with a variable lenght onto the sensor's pressure inlet and the other end to the bottom of the tank. It is mainly used to measure water levels inside of tanks or cisterns.

As the hardware is controlled via RS485, it is necessary to use an USB-Converter for connecting to any PC.

It is possible to connect up to 32 boards to a data bus. An optionally PC-SW can be used for setup and parameterizing (e.g. bus address, calibrating the temperature sensor, calibrating the min. and max. levels). The cycle time is set between 5s to 9h.
