Cross total head passage to be connected with the ram-air pipe, baroport is connected by static pressure passage with the static tube, the ram-air pipe and quiet
The input of pressure pipe and first differential pressure transmitter is connected, the signal output part of the first differential pressure transmitter and the flow
The signal input part of integrating instrument is connected, the pipeline when bi toba flow meter of said structure is only applicable to measure fluid full of pipeline
Interior fluid flow, when the fluid in pipeline only occupies a part for pipeline, i.e., then cannot be accurate in the state of fluid not full packages
Measure the flow of fluids within pipes；In addition when circulated in pipeline be impure more sewage when, using said structure
During the bi toba flow measurement buret road discharge of sewage, the impurity in sewage can block the pitot hole and baroport and total head of pressure head
Pipe and static tube, are directed at measurement failure, i.e., the bi toba flow meter of said structure cannot accurately measure the flow of sewage in pipeline.
The content of the invention
The technical problem to be solved in the present invention be to provide it is a kind of can and meanwhile accurately measurement pipeline in circulation medium be sewage
And the flow measurement device that measures not full packages sewage of the sewage not full of whole pipeline.
In order to solve the above technical problems, a kind of flow measurement device for measuring not full packages sewage of the present invention, with Pitot bar
Flowmeter, the bi toba flow meter includes bi toba flow sensor, the first differential pressure transmitter and flow integrator, the Pitot
Bar flow sensor has connecting pipe and pressure head, and connecting pipe includes ram-air pipe and static tube, and the top of pressure head has total head
Hole and baroport, the hypomere of pressure head is cylindricality joint, and the pitot hole is connected by total head passage with the ram-air pipe, static pressure
Hole is connected by static pressure passage with the static tube, the input of the ram-air pipe and static tube and first differential pressure transmitter
It is connected, the signal output part of the first differential pressure transmitter is connected with the signal input part of the flow integrator, the total head
Pipe is connected with three-way connection, and the static tube is connected with four-way connection, and ram-air pipe and static tube are connected by three-way connection and four respectively
Head is connected with the input of first differential pressure transmitter, and the three-way connection and four-way connection are also connected by screw thread ball valve respectively
There are total head sedimentary deposit tank and a static pressure sedimentary deposit tank, the bottom of total head sedimentary deposit tank and static pressure sedimentary deposit tank is respectively provided with blowoff valve；Also include using

Using the flow measurement device of the measurement not full packages sewage of said structure, the not full packages discharge of sewage in measurement pipeline
When, bi toba flow sensor is installed in pipeline by the bottom wall insertion of pipeline first, make taking for bi toba flow sensor
Pressure head is located substantially at the center of pipeline, and then duct top wall pressure connecting pipe is arranged on the surface roof of pipeline,
Because the three-way connection and four-way connection are also connected with total head sedimentary deposit tank and static pressure sedimentary deposit tank by screw thread ball valve respectively, total head is sunk
The impurity that the bottom of product tank and static pressure sedimentary deposit tank is respectively provided with blowoff valve, therefore sewage can respectively deposit to total head sedimentary deposit tank
With static pressure sedimentary deposit tank, then impurity is emitted by blowoff valve periodically, so the total head of bi toba flow sensor will not be blocked
Hole, baroport and ram-air pipe and and static tube, can accurately measure the flow velocity of sewage in pipeline；Again due to present invention additionally comprises
The second differential pressure transmitter for measuring sewage level in pipeline, the static tube passes through four-way connection and the second differential pressure transmitter
Input be connected, the input of the second differential pressure transmitter is also connected with leads for the duct top wall pressure on duct top wall
Pressure pipe, the signal output part of the second differential pressure transmitter is connected with the signal input part of the flow integrator, therefore can be accurate
The liquid level of sewage in pipeline is measured, the liquid level signal of sewage in pipeline flow integrator is input to, in addition foregoing
Effluent flow rate signal also enters into flow integrator in pipeline, may finally exactly calculate the flow of sewage in not full packages.
Used as a modification of the present invention, the epimere of the pressure head is diversion column, interlude is swelled column, swelled column tool
There are left and right two planes being parallel to each other and former and later two arcwall faces, the pitot hole and baroport are located at the upper of diversion column

Top is connected with the baroport.
When the pressure-taking head of Pitot Pa flow sensor of said structure is in loaded on pipeline, make the left and right inclined-plane on diversion column
The direction of flow of sewage being corresponded in pipeline respectively and going to flow direction, sewage in pipeline enters complete by pitot hole and baroport
Total head flow-guiding channel and static pressure flow-guiding channel are first flowed through before pressure pipe and static tube, due to total head flow-guiding channel and static pressure water conservancy diversion
The set-up mode of passage is to extend vertically upwards, therefore impurity of the sewage in sewage in uphill process can be produced due to Action of Gravity Field
Most of impurity in raw downward trend, i.e. sewage can settle down, and will not enter into total head by pitot hole and baroport
Pipe and static tube, and then the blowing period of total head sedimentary deposit tank and static pressure sedimentary deposit tank can be greatly prolonged, can further improve this
The service efficiency of invention, mitigates the labour intensity of operation element.
As another improvement of the invention, screw thread ball valve is also respectively provided with the ram-air pipe and static tube.In total head
After screw thread ball valve is installed on pipe and static tube dismounting three-way connection, four-way connection and total head sedimentary deposit tank and static pressure can be facilitated heavy
