The utility model discloses a fast installation T-shaped bar flowmeter which comprises a pipeline and a flowmeter body, a first clamping ring and a second clamping ring are buckled on the outer portion after two bosses are in
butt joint, the first clamping ring and the second clamping ring are oppositely arranged, a tensioning
assembly is installed on the first clamping ring, a tensioning
rope is detachably installed on the second clamping ring, and the pipeline is connected with the flowmeter body. The tensioning
rope wound on the tensioning
assembly is tightened by adjusting the tensioning
assembly, so that the first clamping ring and the second clamping ring are close to each other, the distance between the two bosses is adjusted,
welding is not needed, the mounting or dismounting efficiency is obviously improved, whether a sensor and a pressure guide
pipe are blocked or leaked or not can be checked regularly, and the sensor can be cleaned conveniently. Through cooperation of the first clamping ring, the second clamping ring, the tensioning
rope and the tensioning assembly, connection is tight and not prone to loosing, the flow meter is suitable for being used for a flow meter needing frequent maintenance or replacement, meanwhile, the sealing
gasket is a
polytetrafluoroethylene gasket, the sealing performance is good, and the flow meter is suitable for being used for a gas or liquid process pipeline with the high temperature not exceeding 250 DEG C and the pressure not exceeding 1.6 Mpa.
