Described differential elbowmeter, comprise the bend pipe pipeline section of two end band pipe adapters, differential pressure pick-up, counter and housing, output terminal delivery rate signal after described counter is by transducing signal transformation calculations of described differential pressure pick-up, it is characterized in that: described differential pressure pick-up is provided with outer minute-pressure sensing head and interior minute-pressure sensing head, the outer pressure opening and interior pressure opening that are directly installed on described bend pipe pipeline section are set without pressure guiding pipe respectively, described outer pressure opening and interior pressure opening are independently arranged at the tube wall of tube wall outside the bend of described bend pipe pipeline section and curve inner side, described micro-pressure sensor opening inside the bend pipe pipeline section installed, establishes pressure-strain sheet in opening.
A kind of scheme of optimization is, described outer minute-pressure sensing head, interior minute-pressure sensing head are threaded with airtight with corresponding outer pressure opening, interior pressure opening respectively.
A kind of embodiment, at described housing internal battery, the outside surface of housing is equipped with display screen, and the output of described counter connects the signal input part of described display screen.
A kind of embodiment, the axis of the pipe adapter at described bend pipe pipeline section two ends overlaps.
A kind of embodiment, described outer pressure opening and interior pressure opening are opened in the middle part of described bend pipe pipeline section respectively.
The beneficial effects of the utility model are, eliminate pressure guiding pipe and the setting such as exhaust-valve, temperature compensation pipe of elbowmeter, and differential pressure pick-up split is arranged, greatly simplify the structure of elbowmeter, connect differential pressure pick-up at pressure opening by thread seal simply, both can complete assembling and safeguard, reduce the volume of bulk flow gauge, reducing cost, simplified assembling process, is the developing direction of following elbowmeter.
Accompanying drawing explanation

Fig. 2 is the utility model outer surface structure schematic diagram.
In figure, 1-pipe adapter, 2-outer minute-pressure sensing head, 3-pressure-strain sheet, 4-outer pressure opening, 5-differential pressure pick-up, 6-bend pipe pipeline section, 7-housing, 8-interior pressure opening, 9-interior minute-pressure sensing head, 10-display screen.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated: as Fig. 1, shown in 2, described differential elbowmeter, comprise the bend pipe pipeline section 6 of two end band pipe adapters 1, differential pressure pick-up 5, counter, battery and housing 7, the display screen 10 of the measured flow of display housing is equipped with, output terminal delivery rate signal after described counter is by transducing signal transformation calculations of described differential pressure pick-up, and flow signal is outputted to described display screen display metric results, described differential pressure pick-up 5 is provided with outer minute-pressure sensing head 2 and interior minute-pressure sensing head 9, the outer pressure opening 4 and interior pressure opening 8 that are directly installed on described bend pipe pipeline section 6 are set without pressure guiding pipe respectively, described outer pressure opening 4 and interior pressure opening 8 be independently separated be arranged at described bend pipe pipeline section 6 bend outside and curve inner side, described micro-pressure sensor 5 opening inside the bend pipe pipeline section 6 installed, establishes pressure-strain sheet 3 in opening.Therefore micro-pressure sensor 5 tube wall and pressure respectively of curve inner side tube wall outside the bend of bend pipe pipeline section, because the liquid by pipeline section produces centrifugal force, and this centrifugal force can make inner-walls of duct medial and lateral produce the pressure varied in size, the size of this pressure differential evolution value is directly proportional to the mean flow rate of pipeline, the flow velocity that we can flow in pipeline according to the difference acquisition liquid of this pressure, thus can flow metering be realized.
Described outer minute-pressure sensing head 2, interior minute-pressure sensing head 9 are threaded with airtight with corresponding outer pressure opening 4, interior pressure opening 8 respectively.The installation of inside and outside minute-pressure sensing head and bend pipe pipeline section is greatly simplified, eliminates pressure guiding pipe and the setting such as exhaust-valve, temperature compensation pipe of elbowmeter, and differential pressure pick-up split is arranged.
At described housing 7 internal battery, the outside surface of housing is equipped with display screen 10, and the output of described counter connects the signal input part of described display screen 10.Make this flowmeter can independent operating, calculating show metric results.Also can by result of calculation by Signal transmissions out.Here counter is the universal component of liquid flowmeter, carries out the hardware component of signal conversion and process after being determined by experiment parameter.Result of calculation can by the display driver circuit module of band A/D conversion directly in liquid crystal display screen display.Also can by Signal transmissions by metrical information teletransmission.
Here as a kind of Application Example embedded on linear pattern straight pipe, the axis of the pipe adapter 1 at bend pipe pipeline section 6 two ends overlaps.Also can be the pipeline section that 90 degree of pipeline sections bent or other angles are bending.
As a kind of embodiment, as shown in Figure 1, described outer pressure opening 4 and interior pressure opening 8 are opened in the middle part of described bend pipe pipeline section 6 respectively.But the utility model is not limited to outer pressure opening 4 and interior pressure opening 8 in the position of median line.
Because the technical solution of the utility model does not relate to pressure guiding pipe and the setting such as exhaust-valve, temperature compensation pipe of usual elbowmeter, it also avoid that pressure guiding pipe is different for its length and the sensitivity that brings or liquid flow fluctuation adaptation regulates, regulate with temperature compensation, only pressure difference sensing head is tightened onto pressure opening, correct flow metering can be carried out after parameter regulates, prove that its working stability is reliable through repetition test, be suitable for large-scale popularization, owing to greatly simplifying mounting process and appurtenances, equipment cost and installation and maintenance cost all obviously reduce.
