GAS PRESSURE MONITORING CONTROLLER

摘要

PROBLEM TO BE SOLVED: To provide a gas pressure monitoring controller which allows labor costs reduction by eliminating the need for local support as occasion demands and accurately determines a supply amount prediction.

SOLUTION: A gas pressure monitoring controller 100 comprises: a gas cylinder 1 which stores gas and supplies the gas to gas equipment 13; a gas cylinder meter 2 which measures a weight of the gas cylinder 1; a pressure relay 8 which detects a gas pressure in the gas equipment 13; a pressure relay 5 which detects a gass pressure in the gas cylinder 1; an electromagnetic valve 7 which adjusts a gas supply amount from the gas cylinder 1 to the gas equipment 13; a thermometer 10 which measures an outside air temperature around the gas cylinder 1; and a PC 11 which adjusts the electromagnetic valve 7 (including full open/close and half open/close) based on information obtained from the gas cylinder meter 2, pressure relay 8, pressure relay 5, and thermometer 10 to control the gas pressure in the gas equipment 13 to become a prescribed value.
