Abstract
A high-precision quantum flowmeter comprises a tubular cavity and an internal target plate, wherein a guide rod is arranged in the cavity and is parallel to the flowing direction of media; the target plate is arranged on the guide rod and can move in parallel after being impacted by the flowing media; a spring with a damping effect is sleeved on the guide rod; a magnet body is arranged on the target plate; and a magnetic induction hall sensing element is arranged outside the cavity. The utility model has the advantages that the target plate can move in parallel after being pushed by the flow force of the fluid media, thereby avoiding the defect of low measuring precision caused when the moving direction of the target plate is inconsistent with the flowing direction of the fluid media; the flowmeter with simple structure eliminates the interference of complex force actions of the fluid to the measurement, thereby greatly reducing the error in measurement; and a detection mechanism has no requirement for sealing. The flowmeter is applicable in a wider flow measurement range and can measure the flow in a pipe with an extra-large diameter, and the maximum pipe diameter can be more than 1 m. The flowmeter is widely applicable to the measurement of petroleum and impurities fluid as well as the measurement of nonconducting media such as gas, liquid and the like.
Description
[technical field]
The utility model relates to a kind of instrument of liquid material flow metering, particularly a kind of high precision quantum flowmeter.
[background technology]
Target type meter of the prior art generally comprises target sheet, target bar, sensor, signal processor and display device etc., and its adopts force cell to measure that fluid produces the target sheet.When flowing, medium produces kinetic energy in measuring tube, during by the target sheet it there is an acting force, the transmitter that this acting force is constituted by the stress equilibrium bridge of being made up of power induction foil gauge, become the elastic deformation signal that send stressed and lever target bar of target plate or stress tube, by the lever other end contact force cell or condenser type force cell or sensor are installed again, give microprocessor with electrical signal transfer, by microprocessor result of calculation is reached display again and show.The major defect that the target type meter of this structure exists is:
1) the part-structure spare that participates in strain detecting will doublely be done mechanical sealing element simultaneously, because of experiencing the fluid flow forces frequent deformation, causes seal wear at work, leakage phenomenon occurs, and security performance is low;
2) quite complicated the interference greatly of pressure condition of bearing detected fluid owing to strain test element, just becoming the error that is difficult in the measurement structure eliminate disturbs, cause measuring error to strengthen, foil gauge is installed and is difficult to guarantee to be leveled up and down and left-right symmetric for another example, influences measuring accuracy;
3) the target bar transmits the stressed variation of target plate with lever construction, makes target plate produce angular displacement and moves, and causes target plate and rate of flow of fluid direction out of plumb, and this self structure defective has caused its measuring accuracy to be difficult to improve.In addition, the flexible member that adopts in the flowmeter be foil its be subjected to the pressure influence of medium, especially foil easily produces abnormal deformation under the high-pressure work state, causes influencing measuring accuracy.
So in sum, though target type meter of the prior art has wider range of application, the flowmeter survey error is big, precision is low, poor safety performance owing to the defective in self constructing has caused, thereby is unsuitable for the low discharge measurement range.
[summary of the invention]
Technical problem to be solved in the utility model is to overcome existing defective in the above-mentioned prior art, and a kind of high-precision quantum flowmeter is provided.
The utility model has adopted following technical proposal to solve its technical matters: a kind of high precision quantum flowmeter, comprise one section tubular housing, this cavity is built-in with target plate, it is characterized in that: cavity is interior along the parallel guide pole that is equipped with of media flow direction, be equipped with on this guide pole a receptive cavity in-vivo medium when flowing impact and the target plate of parallel displacement on this guide pole, also be nested with one section spring that plays damping target plate parallel displacement effect on the guide pole, be equipped with magnet on this target plate, outside tubular housing, be equipped with a magnetic induction hall sensor.
The utility model compared with prior art has tangible advantage and good effect, target plate in the flowmeter by the mobilization of fluid media (medium) try hard to recommend moving after, produce parallel displacement, thereby avoided the target plate technology disadvantage that measuring accuracy that cause is low with the mobile direction of fluid media (medium) is inconsistent in the prior art; The utility model is simple in structure, has especially adopted the linear Hall element of contactless magnetic induction to substitute the change of strain chip and has sent mechanism, has promptly eliminated the interference of the complicated power effect of fluid to measuring, and measuring error is reduced greatly; The utility model becomes censorship survey mechanism to induction does not have seal request, and this mechanism is damaged does not influence its security performance yet.So the flow range that the utility model is suitable for is wideer, can measure especially big caliber flow, maximum can reach more than the 1M.Be widely used in the measurement in petroleum-type, the impurity fluid, also can be applicable to the measurement of nonconductor medium such as gas, liquid etc.
