Title:
GAS LEAKAGE INSPECTION SYSTEM
Document Type and Number:
Japanese Patent JP2022015555
Kind Code:
A
Abstract:
To provide a gas leakage inspection system with which it is possible to save man-hours in inspecting inner pipes for leakage.SOLUTION: The gas leakage inspection system comprises: an outer pipe P2 to which a gas of prescribed pressure is supplied from a pressure governor 4; a plurality of inner pipes P1 that constitute a gas passage between gas appliances in each user's house and the outer pipe P2; a gas meter 1 provided in the middle of the inner pipes P1; and a monitoring device 3 constituted so as to be capable of communicating with each gas meter 1. The gas meter 1 includes a flow rate measurement unit for measuring a gas flow rate in the inner pipes P1, and a pressure measurement unit for measuring gas pressure in the inner pipes P1. The monitoring device 3 includes a gas leakage assessment unit which, when all of gas appliances are in an unused state in a group G1 composed of a plurality of gas meters 1 to which a gas is supplied through the same pressure governor 4, assesses the presence of gas leakage from the inner pipes P1 where the gas meters 1 in the group G1 are provided, on the basis of the gas pressure measured by all gas meters 1 in the group G1.SELECTED DRAWING: Figure 1
