Abstract

PURPOSE: To continuously mix minute odorant stream with a supply gas in a constant ratio by keeping pressure difference across a flow control valve attached to part of an odorant-dropping line constant.
CONSTITUTION: A gas flow rate in town gas supply conduit 1 is detected by gas flowmeter 9, a signal consisting of factors set corresponding to said flow rate is transmitted by flow rate factor setting device 8 of a flow ratio setting device and then transmitted as a pneumatic signal to flow control valve 6 by convertor 7, which receives said signal. The flow control valve 6 is actuated to determine an amt. of an odorant, and said amt. of the odorant is supplied from dropping monitor 2 through dropping line 5 into conduit 1. Gas pressure near the monitor 2 in conduit 1 is detected and a secondary pressure is determined by the sum of said gas pressure and bias pressure of bias pressure reducing valve 10 set by a setting knob. Pressure difference across the valve 6 is kept constant by automatically controlling the pressure of the odorant flowing through pressurized bias line 11 into odorant tank 3.
