Abstract

PURPOSE:To make unnecessary the needle detection and to prepare the document of a gas consumption quantity by executing the arithmetic processing with a microcomputer and obtaining the fluid flow to pass through respective element valves of a binary digital valve, simultaneously obtaining the integrating flow and executing the collecting and displaying. CONSTITUTION:For one central control computer 14, a gas burner 13 in three plants burner-combusts, a gas pressure sensor 4 is arranged to the upstream side and the downstream side of a binary digital valve 12, a temperature sensor 11 is arranged to the downstream side of the sensor 4 at the downstream side, and after three cutoff valves 7L-7N are arranged in parallel to the downstream of the sensor 11, one gas burner 13 is arranged. A microcomputer 5 executes the PID control, etc., with the deviation of the gas pressure signal and the setting pressure value and sends an opening closing signal through an output interface 10 and a driver circuit 3. Further, the microcomputer 5 knows the gas instantaneous flow, integrates this, also knows the integrating flow, transmits this through communication equipment 15 to a central control computer 14 and displays it.
