The main arithmetic circuit calculates and integrates the flow rate measured by the flow rate sensor to function as a meter, and outputs a unit flow rate signal to the monitoring circuit every time a constant flow rate is integrated. The monitoring circuit integrates the unit flow rate signal and outputs the integrated value to the integrated value abnormality determination circuit of the main arithmetic circuit at fixed time intervals or every time a fixed amount is added. The integrated value abnormality determination circuit compares the integrated value calculated by the main arithmetic circuit with the integrated value input from the monitoring circuit, and determines that the integrated value is normal when the difference between the integrated values is within a preset range. Continue to accumulate as it is,
If it is out of the range, it is determined to be abnormal and an abnormal signal is output to the monitoring circuit. When an abnormality signal is input, the monitoring circuit notifies the abnormality to, for example, a monitoring center.
