FLYPPER ELECTRONIC WATER METER MODELS 7-- DATASHEET 1 DESCRIPTION OF OPERATION The rotating movement of the impeller is transferred by a modulator disc to the sensor system of the FLYPPER electronic counter module. A built-in microprocessor evaluates the sensor signals produced and counts the number of impeller revolutions, detects the direction of rotation and measures the time for each revolution. The microprocessor then calculates the volume flowing through the meter from these parameters and adds up the meter reading. The current flow rate is calculated from the time for one impeller rotation. The FLYPPER module can be read out via M-Bus, LBus or optical interface. The module is powered externally from the M-Bus when this bus is connected. The internal battery is switched off in this case. The built-in lithium battery is rated to give the module a lifetime of over 10 years without an external power supply.
