ABSTRACT:
A high, reduced or alternating pressure fluid measuring system equipped with lines connected to measuring, control or regulating points combined in a collector. The collector is a rapid, multiple coupling and is actuable under operating pressures. The plug or socket is connected to a measuring device with sensors, control or regulating devices. The measuring device has a housing with plural bores, each to receive a pressure transducer and connected to a fluid and a vent channel. The fluid channel leads to a coupling bushing. The plug and socket housing have axially parallel bores to receive a coupling bushing, each with a radial clearance. A spring loaded mechanically actuated check valve and cylindrical valve body is located in each bushing. The outer edge or frontal surface of a bushing sealing shoulder presses against a gasket when closed. The coupling bushing or sealing bush located in the coupling bushing and the gasket form a sealable flow channel. Each plug piece mechanically actuable check valve has an axially displaceable, shackled, flying piston exhibiting a bore and an outlet nipple designed for opening the cylindrical valve body of the associated, mechanically actuable socket check valve and inlet nipple for opening the cylindrical valve body of the plug piece mechanically actuable check valve.
