Description
Technical field
The present invention relates to a kind of Pitot bar mass flowmenter for measuring liquid mass flow in pipeline, more particularly, to one kind
The Pitot bar integrated mass flow meter of fluid-mixing mass flow in measurement pipeline.
Background technology
Mainly include Pitot in the Pitot bar mass flowmenter structure that liquid mass flow is used in measurement pipeline at present
Bar flow sensor, differential pressure transmitter and flow integrator, bi toba flow sensor have connecting pipe and pressure head, connecting pipe
Including ram-air pipe and static tube, the top of pressure head has pitot hole and baroport, and the hypomere of pressure head is cylindricality joint, described
Pitot hole is connected by total head passage with the ram-air pipe, and baroport is connected by static pressure passage with the static tube, described complete
Pressure pipe and static tube are connected with the input of the differential pressure transmitter, the signal output part of differential pressure transmitter and the flow
The signal input part of integrating instrument is connected, and the Pitot bar mass flowmenter of said structure is only applicable to only a kind of stream in measurement pipeline
The mass flow of fluids within pipes when body and fluid are in normal temperature and pressure state, the Pitot bar mass flowmenter of said structure exists
When using, bi toba flow sensor is perpendicularly inserted in pipeline from the side wall of pipeline, allows the central point of pitot hole and baroport
Line on the axis of pipeline, pitot hole against fluid direction of flow, baroport against fluid go flow direction, fluid pipe
In road flow when, total head interface and static pressure interface in connecting pipe upper end distinguish the fluid flowed in output channel total head and
Static pressure, with total head and static pressure that fluid is flowed in pipeline, the stream of fluids within pipes can be calculated by fluid mechanics principle
Amount, fluids within pipes may finally be calculated further according to the density at normal temperatures and pressures of the fluid in pipeline in flow integrator
Mass flow and on integrating instrument show.But it is various fluid-mixings and in non-normal temperature and pressure shape when what is flowed in pipeline
The Pitot bar mass flowmenter of said structure then cannot accurately measure the mass flow of fluid-mixing in pipeline during state.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind and need not separately open up measurement mounting hole in measured pipeline, so that
The Pitot bar integrated mass flow meter for being easily installed and dismantling.
In order to solve the above technical problems, Pitot bar integrated mass flow meter of the present invention, including Pitot bar sensor, differential pressure
Transmitter and flow integrator, the Pitot bar sensor have pressure head, connecting pipe and Pipe installing base, the connecting pipe
Through Pipe installing base, annulus is formed between the connecting pipe and Pipe installing base, also including measurement mixed flow
The densitometer of volume density, the input of densitometer is connected by probe tube with the Pipe installing base, its signal output part
Signal input part with the flow integrator is connected；Also include the drainage tube that can be extend into pipeline, the drainage tube passes through institute
Pipe installing base is stated, the letter of temperature transmitter and pressure transmitter, temperature transmitter and pressure transmitter is connected with drainage tube
Number output end is connected with the signal input part of the flow integrator.
Need first to open up circle on duct wall using the Pitot bar integrated mass flow meter of said structure, when installing and using
Shape mounting hole, the radial dimension of mounting hole be larger than bi toba flow sensor connecting pipe and drainage tube lateral dimension it
With, bi toba flow sensor is mounted on pipeline by Pipe installing base, connecting pipe and drainage tube is extend into pipeline,
Annulus is formed between the connecting pipe and Pipe installing base in due to the present invention, it is also close including measurement fluid-mixing
The densitometer of degree, the input of densitometer is connected by probe tube with the Pipe installing base, its signal output part and institute
The signal input part for stating flow integrator is connected, can be by connecting pipe and pipeline using fluid-mixing in above-mentioned technical characteristic pipeline
The annulus installed between base enters into probe tube, and then the densitometer can be measured that the normal of fluid-mixing in pipeline
Measurement result is simultaneously input to the flow integrator by density under normal temperature and pressure；Again due to also including that drawing in pipeline can be extend into
Flow tube, the drainage tube passes through the Pipe installing base, and temperature transmitter and pressure transmitter, temperature pick-up are connected with drainage tube
The signal output part of device and pressure transmitter is connected with the signal input part of the flow integrator, after above-mentioned technical characteristic
It is measurable go out pipeline in temperature interflow body accurate temperature and pressure, and measurement structure is input to flow integrator, it is final to combine
Density in pipeline under the flow of fluid-mixing, fluid-mixing normal temperature and pressure, and using the actual temperature and pressure in pipeline as
Compensation, can calculate the mass flow of fluid-mixing in pipeline in flow integrator.In sum, Pitot bar of the present invention is integrally
Changing mass flowmenter can accurately measure the mass flow of fluid-mixing in pipeline.
