Conventional pipe fitting connected mode is all adopted in the connection of each pipe fitting in the casing.
Measuring principle of the present utility model is to utilize the coriolis force principle, and coriolis force is exactly to make the pipe movement velocity of rotation that power just leading or that lag behind takes place.
When a pipe rotates around initial point, allow a particle flow outward by pipe from initial point, promptly the linear velocity of particle strengthens gradually by zero, that is to say that particle given energy, the reacting force of Chan Shenging will make the rotational speed of pipe slow down thereupon, i.e. pipe motion lags behind.
On the contrary, allow a particle flow to initial point from the outer end by pipe, promptly the linear velocity of particle is by reducing trend zero greatly gradually, the energy that is to say particle is released,, the reacting force of Chan Shenging will make the rotational speed of pipe accelerate thereupon, i.e. and pipe motion takes place leading.
This pipe movement velocity generation of the rotating power leading or that lag behind that can make just is called coriolis force.
To couple together with same pipe around the two piece identical pipe outer ends of same axis line with the same-phase rotation, when not having particle to flow through in the pipe, connecting pipe is parallel with axis, and when not having particle to flow through in the pipe, because the effect of coriolis force, two swivelling pipe generation phase differential, connecting pipe just not with parallel axes.Generally speaking, the phase differential size of pipe depends on the distortion size of pipe, and the distortion size of pipe only depends on the size of the pipe fluid mass of flowing through.This has just established theoretical foundation for the mass rate of utilizing coriolis force directly to measure fluid.
The vibration that realizes pipe is very easily, encourages with exciting curent.And utilizing electromagnetic induction to obtain two sinusoidal signals respectively at the pipe two ends, two sinusoidal signal phase place extents just directly reflect the size of mass rate.
When crude oil passes through flowmeter, make the pipe generation short time set in the sensor, thereby produce phase differential, change electric signal again into and spread out of, calculate the back video data by the single-chip microcomputer that is provided with in the gauge outfit.
The utility model is installed in well head and does not influence the position of well workover in use, in the scope of oil-out 1m, install the maintenance level, firm, can not tilt.Fig. 3 is a use scheme of installation of the present utility model, the oil-out of device and oil-in should with the flow line keeping parallelism of well head, device is connected the connected mode connection of pressing pipe fitting with the flow line of well head.
