Description
Technical field
The utility model relates to a kind of flow measurement device, particularly one oil recovery winding pipe flow rate metering device.
Background technology
Elbowmeter can occur when the low discharge work lower than flow measurement lower limit: 1, measuring accuracy is low, 2, flow cuts in and out (small-signal excision is large and differential pressure transmitter is on the low side for zero point), and 3, pipeline valve still can have the phenomenon generations such as flow indication (small-signal excision is little and differential pressure transmitter is higher for zero point) after closing.Trace it to its cause and due to the Bending Tube Sensor the choice of diameter stage, low discharge operating condition to be underestimated and to select that flowmeter caliber is bigger than normal to be caused.Owing to considering dilatation and requiring very tight occasion at crushing in new construction, often select large pipe diameter, rate of flow of fluid is low, and the caliber of Bending Tube Sensor is according to the identical the choice of diameter of pipeline, so just cause the lower limit flow velocity that flow velocity allows lower than elbowmeter to use, cause metering inaccurate, the accuracy of impact metering.
Summary of the invention

Embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises pipeline 1, testing tube 2, pressure guiding pipe 5, blowoff valve 6, small pressure difference transmitter 7, large pressure difference transmitter 8, Bending Tube Sensor 9, intercommunicating pore 10, operation valve 11, the crooked position of pipeline 1 is provided with intercommunicating pore 10, testing tube 2 is through the two ends of the connecting tube of intercommunicating pore 10, described testing tube 2 is provided with instrument connection 2.1, the inner fixed bending tube sensor 9 of described instrument connection 2.1, pressure guiding pipe 5 is connected between the endpiece of described testing tube 2 and inlet end, described pressure guiding pipe 5 connects small pressure difference transmitter 7 and large pressure difference transmitter 8, small pressure difference transmitter 7 and large pressure difference transmitter 8 are respectively equipped with operation valve 11, small pressure difference transmitter 7 is connected blowoff valve 6 with the bottom of large pressure difference transmitter 8.
Bending Tube Sensor 9 wherein comprises body 9.1, described body 9.1 is pyramidal structure, body 9.1 comprises circular arc conehead 9.2 and circular arc cone tail 9.3, and described circular arc conehead 9.2 and the side of body 9.1 are respectively equipped with metering orifice 9.4, and described body 9.1 inside is provided with baffle plate 9.5.
Pressure guiding pipe 5 is wherein provided with by disk condenser 3.
The endpiece of testing tube 2 wherein and inlet end connecting tee valve 4.
Principle of work: adopt two differential pressure transmitter technology, namely a Bending Tube Sensor connects two differential pressure transmitters, wherein a range is large, an other range is little, adopts wide range when flow is large, and flow hour adopts small-range, two differential pressure transmitter on-line measurements simultaneously, secondary instrument, according to the current differential pressure value of collection result automatic decision, so both can play the advantage of Bending Tube Sensor wide range ratio, can avoid again the phenomenon because differential pressure transmitter measuring error causes system overproof.
