Description
Technical field
The utility model relates to a kind of fluid flow pick-up unit, especially can measure the bidirectional measurement type elbowmeter of the positive and negative flow of same pipeline fluid.
Background technology
Elbowmeter is this more novel flow measurement device a kind of, can flow in measuring channel and not by the impact of direction of flow, but convection cell does not specifically have decision-making function to which direction flowing, therefore, when aligning reverse flow and all wanting to measure separately, just cannot satisfy the demand.
During commercial Application, due to the impact by season, output and fluid delivery source head position, the situation of the positive and negative two way alternate flowing of fluids within pipes happens occasionally, independent accounting and cost control require can measure flow respective in both direction clearly, and this just proposes higher requirement to the metering outfit at scene.
Utility model content
To the problems of the prior art, the purpose of this utility model is to provide a kind ofly can carry out positive and negative bidirectional measuring to fluids within pipes thus save the bidirectional measurement type elbowmeter of a set of measuring apparatus.
In order to achieve the above object, the technical solution of the utility model is: a kind of bidirectional measurement type elbowmeter, comprise elbow body, temperature transmitter, pressure unit, first differential pressure transmitter, throttling element, the second differential pressure transmitter and secondary main frame table, described temperature transmitter and pressure unit are arranged in elbow body, described first differential pressure transmitter is arranged on one end of elbow body and is connected with throttling element by connecting pipe, and described second differential pressure transmitter is also arranged on the other end of elbow body by connecting pipe.
Can find out that the utility model tool has the following advantages according to such scheme: the utility model is that applying unit saves a set of metering outfit, remarkable in economical benefits, forward and reverse measurement data is that same set of elbowmeter is measured, it also avoid both sides of supply and demand in measurement result, produce unnecessary difference, be conducive to the business accounting of two sides.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Plain edition elbowmeter is conveniently installed.And the utility model adopts a kind of bidirectional measurement type elbowmeter, comprise elbow body, temperature transmitter 1, pressure unit 2, first differential pressure transmitter 3, throttling element 4, second differential pressure transmitter 5 and secondary main frame table 6, described temperature transmitter 1 and pressure unit 2 are arranged in elbow body, described first differential pressure transmitter 3 is arranged on one end of elbow body and is connected with throttling element 4 by connecting pipe, and described second differential pressure transmitter 5 is also arranged on the other end of elbow body by connecting pipe.
Flow to decision maker be made up of a throttling element and differential pressure transmitter, throttling element to be arranged on pipeline and to be connected with differential pressure transmitter by connecting pipe, described temperature transmitter, pressure unit, differential pressure transmitter and flow to decision maker respective signal is sent to main frame table by cable, the flow direction is measured by flowing to decision maker, then the measured medium density under working condition is calculated by temperature signal and pressure signal, the instantaneous delivery of pipeline internal medium is calculated again in conjunction with differential pressure signal, in conjunction with the accumulation carrying out flow that the medium flow direction determined can be correct, by secondary main frame table, the measurement data of different directions is shown.
Flow to the principle of work of judgment means:
Fig. 3 medium flows from left to right, in the process of restriction device, produce pressure differential in the both sides, front and back of restriction device, and P1 is greater than P2, now flow to the current value that differential pressure transmitter that determining device is connected exports with this and be greater than 4mA, assert that this medium flows to as forward.
Fig. 4 medium flows from right to left, in the process of restriction device, produce pressure differential in the both sides, front and back of restriction device, and P2 is greater than P1, now flow to the current value that differential pressure transmitter that determining device is connected exports with this and be less than 4mA, it is reverse for assert that this medium flows to.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
