The tank content is determined by measuring the filling level using the float principle. The FSA-W 4-20 mA converts the measurement result into a current signal and passes it on to the SmartBox® digital display device using a cable. On the scale of the mechanical level indicator type FSA-W 4-20 mA, the tank contents can be read continuously in centimeters as the filling height.
Extension of the probe cable up to a maximum of 100 m
