Abstract
The utility model provides a device capable of measuring the flow of low-flow liquid. According to the device, accurate flow measurement can be carried out on the liquid which is low, unstable and discontinuous in flow. The principle of the device includes the steps of adopting the volume type continuous measurement manner, enabling the liquid to be stored in a box body with the fixed volume, automatically measuring the time for a box body to be filled with the liquid to be measured, and calculating the average flow of the liquid to be measured according to the volume of the box body and the filling time. The relative data obtained through measurement will be automatically saved in a control circuit, meanwhile, the corresponding measured data are displayed through a display terminal of the device, and data sharing of the stored measured data can also be achieved through a standard communication port.
Description
Technical field
The utility model relates to a kind ofly can measure low discharge, instability of flow, the discontinuous liquid flow measuring device of flow.
Background technology
In existing liquid flow mearuement equipment, flow velocity and the pressure of fluid to be measured there is certain requirement, to cross when low when the flow velocity of fluid to be measured, it is large that error in dipping often appears in existing liquid flow mearuement equipment, even unmeasurable problem.
Summary of the invention
The utility model provides the self-measuring device of liquid under a kind of low discharge.This device can carry out exactly flow measurement, and corresponding measurement data is shown by display terminal low discharge, instability of flow, the discontinuous liquid of flow.In addition, this device also provides standard RS485 PORT COM, finish and miscellaneous equipment between data sharing.
The technical scheme that its technical matters that solves the utility model adopts is: adopt positive displacement continuous coverage mode, by liquid being deposited in the casing of fixed volume, automatic gauge goes out the fluid to be measured stream trunkful required time of body, and calculates the average discharge of fluid to be measured according to tank-volumes and filling time.It comprises housing, electromagnetism push rod, liquid meter chamber, water-level float switch, control circuit, overflow vent, valve, liquid inlet, liquid outlet, valve plug, baffle plate, water-level float, guide rod, conduit, display terminal.Under the driving of control circuit, the electromagnetism push rod promotes the valve plug motion by guide rod, realize the switching of valve, flow into the volume of liquid in the liquid meter chamber by metering, realize the automatic measurement of flow, the data of measuring can show by display terminal, and the standard RS485 PORT COM that also can provide by control circuit realizes data remote.
The beneficial effects of the utility model are: the flow measurement problem that solves low discharge, instability of flow, the discontinuous liquid of flow.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described.
Fig. 1 is the organigram of the utility model the first embodiment.
Fig. 2 is the organigram of the utility model the second embodiment.
1. housings among the figure, 2. electromagnetism push rod, 3. liquid meter chamber, 4. water-level float switch, 5. control circuit board, 6. overflow vent, 7. valve, 8. liquid inlet, 9. liquid outlet, 10. valve plug, 11. baffle plates, 12. water-level floats, 13. guide rods, 14. sleeve pipes, 15. display terminals.
Embodiment
In the embodiment shown in fig. 1, comprise housing (1), electromagnetism push rod (2), liquid meter chamber (3), water-level float switch (4), control circuit board (5), overflow vent (6), valve (7), liquid inlet (8), liquid outlet (9), valve plug (10), baffle plate (11), water-level float (12), guide rod (13), sleeve pipe (14), display terminal (15), wherein liquid inlet (8) are placed in the device upper right side.
When the low discharge liquid flow measuring device is worked, control circuit board (5) control electromagnetism push rod (2) moves down, because valve plug (10) links to each other with electromagnetism push rod (2) by guide rod (13), so valve plug (10) also moves down and blocks valve (7), liquid meter chamber (3) beginning filling liquid, the liquid filling for the treatment of liquid meter chamber (3) is when specifying liquid level, water-level float switch (4) action, send the complete signal of metering to control circuit board (5), after control circuit board (5) obtains measuring complete signal, calculate current fluid flow according to liquid filling time and liquid filling volumescope, then, control circuit board (5) control electromagnetism push rod (2) is up mobile, open valve (7), liquid in the evacuation of liquid measurement chamber (3), this metering is complete.Measuring complete data can show by display terminal, also can be by the data sharing between the realization of standard RS485 PORT COM and the miscellaneous equipment.When this low discharge liquid flow measuring device breaks down, in the time of can't realizing the unlatching of valve plug (10), the liquid in liquid meter chamber (3) will be by overflow vent (6) and liquid outlet (9), discharge liquid, control circuit (5) will send fault alarm simultaneously.
In embodiment illustrated in fig. 2, liquid inlet (8) are placed in the device upper left side, and liquid will directly enter in the liquid meter chamber (3) by liquid inlet (8).
Claims (3)
1. low discharge liquid flow measuring device, it comprises housing, the electromagnetism push rod, the liquid meter chamber, the water-level float switch, control circuit, overflow vent, valve, the liquid inlet, liquid outlet, valve plug, baffle plate, water-level float, guide rod, conduit, display terminal, it is characterized in that: under the driving of control circuit, the electromagnetism push rod promotes the valve plug motion by guide rod, realize the switching of valve, flow into the volume of liquid in the liquid meter chamber by metering, realize the automatic measurement of flow, the data of measuring can show by display terminal, the standard PORT COM that also can provide by control circuit realizes data remote.
2. a kind of low discharge liquid flow measuring device according to claim 1, it is characterized in that: the liquid inlet is positioned at the device upper right side, and liquid is by in the baffle plate influent measurement chamber.
3. a kind of low discharge liquid flow measuring device according to claim 1, it is characterized in that: the liquid inlet is positioned at the device upper left side, and liquid flows directly in the liquid meter chamber by conduit.
