Mounting apparatus for a pressure gage

A cover retention mechanism for releasably locking a cover to a base such as a gage housing. The cover retention mechanism includes a base lock having a receiver and a receptacle, and a cover lock having a latch attached to an end of a flexible arm. The latch is selectively movable between a retracted position wherein the latch engages the receptacle to prevent rotational movement of the cover with respect to the housing from the closed position toward an open position, and an extended position wherein the latch is removed from the receptacle and the cover is rotatable with respect to the housing from the closed position toward the open position.

Gage

An enclosure for a gage including a housing and cover. The cover includes one or more mounting lugs and the housing includes one or more mounting mechanisms. Each mounting mechanism includes an inclined ramp to facilitate removal of the cover from the housing by rotational movement of the cover with respect to the housing.

Pressure transmitter

A flowmeter for measuring fluid flow including a body having a receptacle including a cavity formed by a threadless cylindrical side wall, a stopper adapted to be inserted into the cavity of the receptacle including a generally cylindrical threadless shank having an annular groove, and a clip member slidably located in a passage of the body. The clip member is slidable between a first position wherein the clip member is located within the annular groove of the stopper to prevent removal of the stopper from the body, and a second position wherein the clip member is located outside of the annular groove of the stopper whereby the stopper may be longitudinally removed from the receptacle of the body.
