  • Process gas flow control module
    Patent number: 4174733
    Abstract: A module which integrates into a single block a process gas flow control system for precisely metering the flow of gas fed into a furnace diffusion tube or other utilization device. The block is formed of a chemically-inert body having cavities therein for nesting a gas filter, a pressure-regulator, a flowmeter, a pressure indicator and the other components of the system necessary to set the flow rate and pressure of the gas. These components are intercoupled by internal bores in the block which define flow passages that communicate with the cavities.
