Abstract

PURPOSE:To reduce the destructive ratio of a data train, by providing a count means at each terminal device and transmitting the information representing the presence of the terminal device at the time zone set to each clock means and the measuring information. CONSTITUTION:To a shift right input terminal R of a shift register 713 the data terminal D of which has H logic at all times, a pulse is applied from a turbine flow meter 711 via a buffer 712, and output terminals Q1-Q4 are sequentially at H logic. To a shift left input terminal L, a marker signal 612 indicating the presence of a terminal device outputted from a gate 714 every rest of clock means 716 of the terminal device is applied. When a counter constituting the clock means 716 is in coincidence with the content of ROM constituting a set means 717, the status of the output terminal Q1 of the shift register 713 is read out at gate 715 to output a data signal 611.
