Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type embodiment is described in further detail.
For mentioned in the utility model embodiment oil pipe four-way 3, reducer tee 11, the left end of equal tee 14, the right side
End, is defined by Fig. 1 left and right directions, is merely for convenience of description, without the meaning of restriction.
It should be noted that the flowmeter of normal use is general to have 5 waypoints, i.e., respectively full scale 10%,
15%th, 20%, 50%, 100%.In checking flow timing, first, treat checking flow meter 1 and carry out Initialize installation, make to treat school
Test flowmeter 1 self to detect, it is ensured that the flow value that it shows at each waypoint is normal, that is, shows that the waypoint should be corresponding
Flow value.Also, 80% value of the full scale of flowmeter 1 to be verified is read as detected value.
The utility model embodiment provides a kind of flowmeter on-line testing system, as shown in Figure 1, flowmeter to be verified
1 is arranged on the waterflood-transmission line 4 between water injection unit 2 and the left port of oil pipe four-way 3.On-line testing system includes：With oil pipe four
The first verification pipeline 5, the proving flowmeter 6 being arranged on the first verification pipeline 5 of logical 3 right output port connection；Flow computer
7, electrically connected respectively with flowmeter 1 to be verified and proving flowmeter 6；The accuracy class of proving flowmeter 6 is higher than flow to be verified
The accuracy class of meter 1.
Proving flowmeter 6 refers to the accuracy class flowmeter higher than the accuracy class of flowmeter 1 to be verified.Citing comes
Say, when flowmeter 1 to be verified is secondary standard instrument, (percent error of the secondary standard instrument is 0.1,0.2,0.35,0.5
Deng), proving flowmeter 6 can be that (percent error of the primary standard instrument is 0.005,0.02,0.05 to primary standard instrument
Deng).
The operation principle for the flowmeter on-line testing system that the utility model embodiment provides is as described below：
80% value of the full scale of flowmeter 1 to be verified is read as detected value, then, using water injection unit 2 to water filling
Pipeline 4 and first verifies water filling in pipeline 5, until the flow value shown on proving flowmeter 6 is equal to the detected value.Now, see
Examine whether the flow value shown on flowmeter 1 to be verified is the 80% of its full scale.
If the flow value shown on flowmeter 1 to be verified is the 80% of its full scale, illustrating flowmeter 1 to be verified just
Often, it is not necessary to be corrected；If the flow value shown on flowmeter 1 to be verified is not the 80% of its full scale, need pair
The flowmeter 1 to be verified carries out pointwise correction.In above process, flow computer 7 gathers flowmeter 1 to be verified and mark in real time
The flow value that quasi- flowmeter 6 is shown, and the difference of two flow values is provided, and COEFFICIENT K is generated according to the difference of two flow values
(COEFFICIENT K is common for this area, refers generally to flowmeter before being taken into use, and producer is filled using the measurement for meeting required precision
Marked ratio pair is put, be then calculated a coefficient, flow computer 7 herein can be used as the measurement apparatus).In order to just
In understanding, COEFFICIENT K can be considered as to an overall trend line, K1, K2, K3, K4, K5 mentioned below can be considered as the entirety and become
Different piece on gesture line, i.e. segment factor.
When two flow values that flow computer 7 gathers are unequal, it is necessary to which treating checking flow meter 1 carries out point-by-point school
Just, it is specific as follows：
10% value of the full scale of flowmeter 1 to be verified is read as the first detected value, using water injection unit 2 to water injection pipe
Line 4 and first verifies water filling in pipeline 5, until the flow value shown on proving flowmeter 6 is equal to first detected value, passes through stream
Amount computer 7 gathers the flow value that now flowmeter 1 to be verified is shown with proving flowmeter 6, and according to the difference of two flow values
Value generation segment factor K1, then K1 is transmitted to flowmeter 1 to be verified, replace flowmeter 1 to be verified using flow computer 7
In original segment factor, and then complete to treat the correction of this waypoint of checking flow meter 1.
Similarly, respectively using 15%, 20%, 50%, 100% value of the full scale of flowmeter 1 to be verified as second,
3rd, the four, the 5th detected value, water filling in pipeline 5 then is verified to waterflood-transmission line 4 and first using water injection unit 2, until standard
The flow value shown on flowmeter 6 is respectively equal to second, third, fourth, fifth detected value, and this is gathered by flow computer 7
When the flow value that shows of flowmeter 1 to be verified and proving flowmeter 6, and segment factor is generated according to the difference of two flow values
K2, K3, K4, K5, K2, K3, K4, K5 are then transmitted separately to flowmeter 1 to be verified using flow computer 7, school is treated in replacement
The original segment factor of flowmeter 1 is tested, and then completes to treat the correction of the corresponding segments point of checking flow meter 1.
It can be seen that the flowmeter on-line testing system that the utility model embodiment provides carries out school treating checking flow meter 1
When testing, without dismantling flowmeter 1 to be verified, flowmeter 1 to be verified and proving flowmeter 6 only need to be gathered by flow computer 7
In the flow value that each waypoint is shown, segment factor is generated according to the difference of two flow values and point-by-point school is carried out to each waypoint
Just.Based on above-mentioned, the utility model embodiment is not only time saving and energy saving when treating checking flow meter 1 and being verified, and ensures
