ABSTRACT:
A gas-flow sensor features delayed-action response to physical changes in gases as they flow through the sensor, thus avoiding transient flow-metering displacements in response to such change. The delayed-action response is attributable to blind hole and blind-bore configurations within which cylindrical plunger elements must displace in the course of changing gas flow, and the delayed-action response is controlled by provision of predetermined clearances between parts that telescope in the course of sensor operation.
