Abstract
The utility model provides a kind of metering pump flow measurement device, including metering pump, tank gage and graduated cylinder；The metering pump input valve group connection graduated cylinder, the interior setting tank gage of graduated cylinder.The measuring device is not interfered by metering pump rate of discharge fluctuation, but calculated by the liquid level difference of the amount liquid within the cartridge at the place for measuring pump intake, the liquid level gauge to play a decisive role is not continuously to measure, only record the level value of beginning and end moment, so as to calculate the flow of metering pump, accuracy is high.
Description
Technical field
The utility model belongs to metering pump technical field, and in particular to a kind of metering pump flow measurement device.
Background technology
Metering pump is a kind of variable positive displacement pump that can meet various technological processes, and metering pump is measuring metered flow
When, the quality or volume of output liquid are typically measured in specified pressure, specified time, and then calculate the specified stream of metering pump
Amount.Metering pump is pumped as reciprocating volume formula, small flow it is in the majority, outlet pressure is unstable, therefore existing big absolutely on the market
Most flowmeters all can not be measured accurately.Even if using high-precision mass flowmenter and there are certain error, in addition when
Between accumulation, error will amplify, and pump discharge is unstable, cause flowed fluctuation very big, for mass flowmenter
There is larger error.
Invention content
According to defect of the existing technology, the utility model provides a kind of measuring device, using volume divided by time
Algorithm, to obtain the flow of metering pump.Liquid level difference is measured in the very high graduated cylinder of circular arc degree.
Technical solution is used by the utility model：A kind of metering pump flow measurement device, including metering pump, tank gage
And graduated cylinder；The metering pump input valve group connection graduated cylinder, the interior setting tank gage of graduated cylinder.
Further, the measuring device further includes fluid level transmitter and processor, and the tank gage connects level transmitting
Device, fluid level transmitter are connected by signal with processor, and processor connection metering pump simultaneously controls metering pump to start to work and stop
Work.
Further, solenoid valve is set between the metering pump and graduated cylinder, and solenoid valve passes through signal connection processing device.
Further, the metering pump is provided with hand valve.
The beneficial effects of the utility model are：The measuring device is not interfered by metering pump rate of discharge fluctuation, but logical
What the liquid level difference for the amount liquid within the cartridge for crossing the place of metering pump intake was calculated, the liquid level gauge to play a decisive role is not continuously to survey
Amount only records the level value of beginning and end moment, and so as to calculate the flow of metering pump, accuracy is high.
Description of the drawings

Specific embodiment
Specific embodiment 1
1 pair of the utility model is described further below in conjunction with the accompanying drawings, a kind of metering pump flow measurement device, including metering
Pump 1, tank gage 2 and graduated cylinder 3；The metering pump 1 is equipped with hand valve 4, and metering pump 1 inputs valve group connection graduated cylinder 3, set in graduated cylinder 3
Tank gage 2.
Metering pump discharge measuring process be：Firstly the need of the very high graduated cylinder 3 of a circular arc accuracy, into graduated cylinder 3
Liquid is injected, and records initial liquid level value, then starts metering pump 1, in certain time of measuring, under liquid level is continuous in graduated cylinder 3
Drop closes metering pump 1, by the termination level value of 2 recorded amounts liquid within the cartridge of tank gage, finally according to 3 diameter of graduated cylinder, start and
The liquid level for terminating moment is poor, and three parameters of time of measuring calculate the flow of metering pump.
Specific embodiment 2
The utility model is described further with reference to attached drawing 2, a kind of metering pump flow measurement device, including metering pump 1,
Tank gage 2, graduated cylinder 3, fluid level transmitter 6 and processor 7；The metering pump 1 is equipped with hand valve 4, metering pump input valve group connection amount
Cylinder 3 sets solenoid valve 5 between metering pump 1 and graduated cylinder 3, by signal connection processing device 7, the graduated cylinder 3 is interior to be set solenoid valve 5
Tank gage 2, tank gage 2 connect fluid level transmitter 6, and fluid level transmitter 6 is connected with processor 7, and processor 7 connects metering pump 1 simultaneously
Control metering pump starts to work and is stopped.
Metering pump discharge measuring process be：
1st, firstly the need of the very high graduated cylinder 3 of a circular arc accuracy, liquid is injected into graduated cylinder 3；
2nd, the diameter, the stroke scale of metering pump 1, time of measuring of graduated cylinder 3 are set on processor 7；
3rd, metering pump hand valve 4 is opened, starts metering pump 1；
4th, processor 7 controls solenoid valve 5 to open, and starts to measure, 2 measurement amount liquid within the cartridge of tank gage is starting to measure at this time
The initial liquid level value of moment, and initial liquid level value is sent to processor 7 by fluid level transmitter 6；
5th, the liquid level in the range of the time of measuring in graduated cylinder 3 is constantly declining, and simultaneous processor 7 carries out countdown；
6th, when countdown is that zero in a flash, processor 7 controls solenoid valve 5 to close, stop measuring, tank gage 2 is remembered again
The liquid level in graduated cylinder 3 is recorded, as level value is terminated, tank gage 2 sends processor to by level value is terminated by fluid level transmitter 6
7；
7th, processor 7 is according to 3 diameter of graduated cylinder, and initial liquid level value and the liquid level for terminating level value are poor, time of measuring three
A parameter calculates the flow of metering pump automatically.
