Abstract
The invention relates to a flowmeter and solves the problem that the existing flowmeter has large errors when measuring fluid conveyed through a guide channel. The flowmeter comprises a guide channel (1) and an intelligent meter (6). The bottom of the guide channel (1) is provided with a pressure sensor (5). A force sensor (4) is fixed right in front of the guide channel (1). The measuring end of the force sensor (4) is provided with a thrust plate (3). Both the force sensor (4) and the pressure sensor (5) are electrically connected to the intelligent meter (6). A thrust surface (7) of the thrust plate (3) is perpendicular to the horizontal plane. The fluid (2) is arranged in the guide channel (1). The flowmeter is especially suitable for accurately measuring flows of different fluids.
Description
Technical field
The present invention relates to a kind of flowmeter, particularly a kind of for measuring the measurement mechanism of the fluid flow that diversion trench (or diversion channel) carries.
Background technology
During fluid that prior art is carried in measuring diversion trench (or diversion channel), it is generally the employing differential flowmeter.Its work is former: tensimeter is housed in diversion trench, measure hydrodynamic pressure, this measuring method can only be got one or more pressure of fluid, calculate rate of flow of fluid according to pressure, because the flow velocity in the same cross section of fluid is inhomogeneous, make the flow velocity and the actual flow velocity that measure not be inconsistent, cause the measuring error of flowmeter of this kind of structure generally bigger than normal.
Summary of the invention
The invention provides a kind of flowmeter, solved the measuring error problem bigger than normal that existing flowmeter exists when measurement utilizes chute to carry fluid.
The present invention solves above technical matters by the following technical programs:
A kind of flowmeter, comprise diversion trench and intelligent instrument, bottom at diversion trench is provided with pressure transducer, dead ahead at diversion trench is fixedly installed force cell, be provided with the impulse force plate on the dynamometry end of force cell, force cell and pressure transducer are electrically connected to intelligent instrument respectively, and the shock surface of impulse force plate is vertical with surface level, are provided with fluid in diversion trench.
The angle of diversion trench and surface level is less than 80 degree.
The object of the invention is to overcome the problem of existing flowmeter survey bigger error, simple in structure, can reach the purpose of different fluids being carried out to accurate-metering.
the accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with embodiment, the present invention is described in detail.
A kind of flowmeter, comprise diversion trench 1 and intelligent instrument 6, be provided with pressure transducer 5 in the bottom of diversion trench 1, be fixedly installed force cell 4 in the dead ahead of diversion trench 1, be provided with impulse force plate 3 on the dynamometry end of force cell 4, force cell 4 and pressure transducer 5 are electrically connected to intelligent instrument 6 respectively, and the shock surface 7 of impulse force plate 3 is vertical with surface level, is provided with fluid 2 in diversion trench 1.The suffered impulse force of impulse force plate 3 converts electric signal to by force cell 4 and sends into intelligent instrument 6, pressure transducer 5 is sent the pressure signal recorded into intelligent instrument 6, the accurately program of Fluid Computation flow is set in intelligent electric meter 6, by obtaining the accurate flow of fluid after system calibrating.
Claims (2)
1. a flowmeter, comprise diversion trench (1) and intelligent instrument (6), it is characterized in that, be provided with pressure transducer (5) in the bottom of diversion trench (1), be fixedly installed force cell (4) in the dead ahead of diversion trench (1), be provided with impulse force plate (3) on the dynamometry end of force cell (4), force cell (4) and pressure transducer (5) are electrically connected to intelligent instrument (6) respectively, the shock surface (7) of impulse force plate (3) is vertical with surface level, is provided with fluid (2) in diversion trench (1).
2. a kind of flowmeter according to claim 1, is characterized in that, diversion trench (1) is less than 80 degree with the angle of surface level.
