Abstract

The utility model provides a novel device used for measuring the flow quantity of liquid. The utility model is suitable for measuring the flow quantity of gas and liquid. The utility model is characterized in that the utility model uses an infrared luminous tube and a light sensitive receiving tube as a sensor and adopts a special integrated circuit as correction and counting. Because friction only exists on an impeller shaft, and the special integrated circuit is adopted, the flow quantity of liquid and an indicated value of a meter are consistent.

Description

Vane wheel type electronic flow meter
The present invention relates to a kind of measurement instrument, particularly a kind of vane type measurement instrument of measuring fluid flow.
Existing vane type measurement instrument has mechanical and electromagnetic type.The mechanical type instrument is the kinetic energy drive impeller rotation by fluid, drive the kinematic train of worm screw, worm gear and gear again by impeller, by gear counter numeral is shown at last, because the mechanical type instrument is through multi-stage gear and worm screw, worm-drive, its friction ratio is bigger, makes the flow of fluid and the relation property of the actual indicated value of instrument that error be arranged.Particularly the error during low discharge is bigger.And electromagnetic meter is because the effect of magnetic field force only is applicable to big flow instrument.And its manufacturing accuracy height, the cost height is so range of application is restricted.
The objective of the invention is to provide a kind of improved flow measurement instrument.It promptly can revise the flow of fluid and the error that the instrument indicated value exists, and because cost is lower than existing instrument, range of application is very extensive.
The present invention utilizes fluid dynamic energy to promote the impeller rotation, and the dish that is in the light of 1 aperture is installed at an end of impeller shaft.Two ends at the dish that is in the light are equipped with infraluminescence pipe and photosensitive receiving tube respectively.When impeller drove that being in the light spirals and forward to aperture on the dish that is in the light and luminotron and receiving tube consistent location, the resistance of receiving tube diminished, and electric current passes through.When aperture forwarded other position to, it is big that the resistance of receiving tube becomes, current cut-off.So the dish that is in the light, infraluminescence pipe and photosensitive receiving tube have just been formed sensor.The pulse that special IC sends sensor is come out by liquid crystal display displays at last through counting, frequency division, selection frequency division, storage.Power supply is to be used for battery.
Below with reference to accompanying drawing invention is described in further detail:
Fig. 1 is the longitudinal sectional drawing of pulse body structure of the present invention.
Fig. 2 is pulse-generating circuit figure of the present invention.
Fig. 3 is the family curve before the correction of the present invention.
Fig. 4 is the revised family curve of the present invention.
Fig. 5 is the total wiring diagram of electric part of the present invention.
Fig. 6 is the special-purpose integrated package vertical view of the present invention.
With reference to Fig. 1, fluid blows on the impeller (9) from import.Make impeller (9) with dish (2) rotation of being in the light, on the dish (2) that is in the light an aperture is arranged.When aperture forwards to consistent with infraluminescence pipe (4) and photosensitive receiving tube (7) time, the resistance of receiving tube (7) diminishes, and electric current passes through.When aperture forwarded other position to, it is big that the resistance of receiving tube (7) becomes, and electric current is obstructed.So just form pulse signal.Produce circuit via count pulse, produce a string corresponding pulse, this series impulse is sent into integrated circuit as input signal.Standard time clock produces 1~2HZ square wave, in each cycle count pulse is sampled, and draws interior rotating speed of corresponding time.Control corresponding frequency dividing circuit (promptly selecting Ci) by tach signal in this time, can count out the volume that fluid flows out in this time.
Desirable propeller flowmeter characteristic dotted line as shown in Figure 3, in the case, no matter how flow change, always revolution/liter keep certain value.But actual property shown in solid line among Fig. 3 like that, at first impeller overcomes bearing friction power and begins rotation, has minimum flow.Thereafter, with the variation revolution of flow/liter also more or less change.For addressing this problem, the curve of Fig. 3 is divided into the K section, in every section rotating speed, choose a corresponding constant value, as the rotating speed in the wheel speed/liter value Ci, then curve should become the form of Fig. 4.

Claims (5)

1, one by housing (1) (8) (12), impeller (9), sensor (2) (4) (7), the flow measurement device that counter and display (6) are formed is characterized in that sensor adopts photovalve, counter adopts special-purpose integrated package, and display adopts liquid crystal display.
2, by the flow measurement device of power requirement 1 regulation, it is characterized in that photovalve is infraluminescence pipe and photosensitive receiving tube.A circle that has the hole dish (2) that is in the light is arranged between two pipes.Be in the light dish (2) available metal or plastics are made.
3,, it is characterized in that special-purpose integrated package (6) adopts cmos circuit by the flow measurement device of claim 1 or 2 regulations.
4,, it is characterized in that by the counting of the K system in the special IC and can select frequency division to revise error between fluid flow and the instrument indicated value by the flow measurement device of claim 3 regulation.
5, by the flow measurement device of claim 3 regulation, it is characterized in that power supply (5) adopts zinc-silver oxide cell, need not, other battery also is fine.
