Abstract
An electromagnetic flow-rate measurement system for measuring flow-rate values of a fluid is disclosed. Detection units measure the flow-rate values of the fluid. A meter board, which connects to the detection units via a common bus-line, collects the flow-rate values. The detection units include a first communications circuit which is connected between two ends of an exciting coil and server both to transmit flow-rate signals or cumulative flow-rate signals to a meter board in synchronization with an alternating waveform voltage of a common bus-line, and to receive signals from the meter board in synchronization with the alternating waveform voltage. The meter board encompasses a second communications circuit which is connected to the common bus-line and serves both to transmit signals to the plurality of detection units in synchronization with the alternating-current waveform voltage, and to receive signals from the detection units in synchronization with the alternating waveform voltage. The electromagnetic flow-rate measurement system facilitates remote centralized collection of data from a single meter board and can be applied, for example, to the detection of household water consumption.
