Abstract

A gas flowmeter or regulator including a capillary tubing for delivering a desired and predetermined mass flow of a gas from the outlet of the meter.

Claims

1. In a meter for regulating the flow of a fluid, the combination of:

pressure regulating means for delivering a desired and uniform mass flow of a fluid to an outlet;

a first conduit connected to said outlet;

a pressure gauge connected to said first conduit;

a capillary tubing one end of which is connected to said first conduit;

a second conduit connected to the other end of said capillary tubing and having an outlet;

an outlet valve connected to the outlet of the second conduit; and

a flushing valve connected to said second conduit upstream of said outlet valve.

2. In a meter for regulating the flow of a fluid, the combination of:

pressure regulating means for delivering a desired and uniform mass flow of a fluid to an outlet;

a first condUit connected to said outlet;

a pressure gauge connected to said first conduit;

a capilary tubing one end of which is connected to said first conduit;

a second conduit connected to the other end of said capillary tubing and having an outlet; and

means disposed between said pressure regulating means and said capillary tubing for bleeding off a portion of the fluid to increase the velocity of the flow of fluid through said regulating means and to control the same.
