Document Type and Number:
Japanese Patent JP5627833
Kind Code:
B2
Abstract:
A natural gas odorant injection system for injecting odorant into a main gas line includes a by-pass line, an odorant tank, a flowmeter, a control valve, and a controller communicably coupled to the flowmeter and the control valve. The by-pass line includes an inlet that is in fluid communication with an upstream section of the main gas line, and an outlet that is in fluid communication with a downstream section of the main gas line. The odorant tank, the control valve, and the flowmeter are disposed in the by-pass line. The flowmeter senses a characteristic of a fluid flow through the flowmeter and, accordingly, generates a fluid flow signal. The controller is programmed to operate the control valve based on the fluid flow signal received from the flowmeter.
