Description
Technical field
The utility model relates to a kind of self-action volumetric method flow rate test meter, belongs to flow rate test meter technical field.
Background technology
In the scientific research of the fluid media (medium) such as water body, oil body, flow often as the characterising parameter of an outbalance, in order to carve
drawthe motion state of fluid is described.Thus for the flow related assays of fluid to be studied, seem particularly important.
At present, in the correlated curriculums such as undergraduate's hydraulics, fluid mechanics, often based on volumetric method; utilize beaker and stopwatch; coordinate through two people, the water yield in the unit interval is measured, tries to achieve the flow rate test value under environment to be measured in conjunction with density conversion and flow definition.Aforesaid way can be similar to be obtained flow rate test value, but can produce certain error to measurement result in view of two people's cooperate degrees, subjective factor impact such as reaction time delay etc.
Utility model content
In order to solve above-mentioned Problems existing, the utility model discloses a kind of self-action volumetric method flow rate test meter, its concrete technical scheme is as follows:
A kind of self-action volumetric method flow rate test meter, comprises shell, described enclosure be provided with for
containthe storage container of dress liquid, the top of described storage container is provided with water inlet pipe, the xsect of described water inlet pipe is provided with timing water check valve, and the bottom of described storage container is provided with weighing instrument, and described weighing instrument is provided with can mass conversion show the display of reading.
Described outer casing bottom is smooth, for being flatly placed in desktop or testing table.
The automatic electric valve of stopwatch and automatic closing timing water check valve is provided with in described timing water check valve, described stopwatch is connected by circuit connected in series with automatic electric valve, when stopwatch timing terminates, connect circuit, automatic electric valve is closed automatically, and timing water check valve stops liquid to continue to enter storage container.
Be provided with the chip for quality conversion being become volume in described display, this chip is connected with density value input port.
Described display is provided with reading display screen, and described display screen is arranged on the surface of display.
Principle of work of the present utility model is:
The utility model, in use, from water inlet pipe towards infusion fluid storage container, timing water check valve can be closed to infusion fluid in storage container according to time controling, not only facilitates and automatically closes down infusion fluid, remember the time of infusion fluid simultaneously.Weighing instrument in display can weigh up the quality of the liquid be input in storage container, the density of infusion fluid in display, converted by chip, just the volume of the liquid be input in storage container can be obtained, again according to the time, can converse the flow of liquid, computing formula is as follows: Q=V/t=(m/ ρ)/t=m/ ρ t.
The beneficial effects of the utility model are:
The utility model, by the time of timing water check valve record to infusion fluid in storage container, and automatically stop towards infusion fluid in storage container within the time of setting, timing is more accurate; Display can according to the quality of the time of infusion fluid and infusion fluid, in conjunction with the density of liquid, converse the flow of liquid, and by the display of this flow number on a display screen, improve the accuracy of experiment and research and the easy experimentation of calculated flow rate, there is good using value.
