ABSTRACT:
A flowmeter for measuring the flow of fluids through a conduit is disclosed and includes a body having a passageway therethrough mounted in communication with a conduit. A cover is assembled to the flowmeter body and contains a flowmeter device which measures the flow of fluids in the body passageway. An O-ring is compressed between the body and cover to seal the flowmeter device relative to the body passageway, and the O-ring is also exposed to fluid pressure within the body passageway. When excessive pressure is encounterred within the flowmeter, the resistance of the O-ring to movement is overcome and the O-ring can be moved to a position enabling the excessive pressure to be vented to atmosphere. No damage to the flowmeter occurs when the pressure is relieved, and the flowmeter can be re-set on site without any need for replacement of components.
