The utility model discloses can detect flow uncovered, little water gaging to the precision that detects is high.

Description

A kind of uncovered liquid flowmeter
Technical field
The utility model relates to a kind of flowmeter, is specifically related to a kind of uncovered liquid flowmeter.
Background technology
Existing liquid flowmeter is all for detecting the liquid in closed conduit, the ducted liquid of non-tight can not be measured, simultaneously in the process of continuous detecting small amount of water flow, because the flow of water is less, therefore the precision of liquid flowmeter detection is not high, existing liquid flowmeter can not detect the average discharge of discontinuous working fluid within a period of time simultaneously, such as, in energy-conserving and environment-protective field, existing liquid flowmeter can not the flow of uncovered small amount of water that cools and isolates from flue gas of continuous coverage.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, provides a kind of uncovered liquid flowmeter, and this flowmeter can detect flow that is uncovered, small amount of water, and the precision detected is high.
For achieving the above object, uncovered liquid flowmeter described in the utility model comprises liquid trap, fluid level transmitter, volume pump and host computer, the thief hatch of fluid level transmitter is connected with the side bottom liquid trap, the output terminal of fluid level transmitter is connected with the input end of host computer, the output terminal of host computer is connected with the control end of volume pump, the liquid outlet bottom the liquid inlet of volume pump and liquid trap.
Described host computer comprises display and controller, and the output terminal of fluid level transmitter is connected with the input end of controller, and the output terminal of controller is connected with the control end of the input end of display and volume pump.
Described controller comprises comparer, pulse producer, totalizer and data processor, the input end of comparer is connected with the output terminal of fluid level transmitter, the output terminal of comparer is connected with the input end of data processor, and data processor is connected with the control end of pulse producer, totalizer, display and volume pump.
Described volume pump is electromagnetic pulse metering pump.
The internal diameter of described liquid trap is 8mm, and the height of liquid trap is 250mm.
The utility model has following beneficial effect:
Uncovered liquid flowmeter described in the utility model operationally, liquid enters into liquid trap, fluid level transmitter detects the liquid level information of liquid in liquid trap in real time, whether host computer is greater than default liquid level threshold values according to the liquid level that described liquid level information judges in liquid trap, when the liquid level in liquid trap is greater than default liquid level threshold values, then control volume pump to control once, the flow that liquid enters into liquid trap is obtained according to the work times of volume pump in one-period and the volume of the every work extraction liquid of volume pump, structure is simple, be applicable to the flow detection of small amount of water, the precision measured is high.
Further, described volume pump is electromagnetic pulse metering pump, and because electromagnetic pulse metering pump has the repeatability of 0.5%, time measurement accuracy is high, and every subpulse lifting rate can make measuring accuracy error of the present utility model be less than 0.5% after demarcating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 be liquid trap, 2 be fluid level transmitter, 3 be host computer, 4 for volume pump.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to figure 1, uncovered liquid flowmeter described in the utility model comprises liquid trap 1, fluid level transmitter 2, volume pump 4 and host computer 3, the thief hatch of fluid level transmitter 2 is connected with the side bottom liquid trap 1, the output terminal of fluid level transmitter 2 is connected with the input end of host computer 3, the output terminal of host computer 3 is connected with the control end of volume pump 4, the liquid outlet bottom the liquid inlet of volume pump 4 and liquid trap 1.
It should be noted that, described host computer 3 comprises display and controller, and the output terminal of fluid level transmitter 2 is connected with the input end of controller, and the output terminal of controller is connected with the control end of the input end of display and volume pump 4; Controller comprises comparer, pulse producer, totalizer and data processor, the input end of comparer is connected with the output terminal of fluid level transmitter 2, the output terminal of comparer is connected with the input end of data processor, and data processor is connected with the control end of pulse producer, totalizer, display and volume pump 4; Volume pump 4 is electromagnetic pulse metering pump, the liquid of each work extraction 0.08mL of described electromagnetic pulse metering pump, and filling maximum pulse rate is perhaps 10Hz; The internal diameter of liquid trap 1 is 8mm, and the height of liquid trap 1 is 250mm.
Specific works process of the present utility model is:
The opening of liquid through liquid trap 1 top enters into liquid trap 1, fluid level transmitter 2 detects the liquid level information of liquid in liquid trap 1 in real time, and described liquid level information is forwarded in comparer, whether the liquid level that comparer judges in current liquid trap 1 according to described liquid level information is greater than default liquid level threshold values, when the liquid level in current liquid trap 1 is greater than default liquid level threshold values, then produce the first electric signal, and described first electric signal is forwarded in data processor, data processor makes totalizer add 1 according to described first electric signal, produce control signal again, and make pulse producer send pulsatile once signal by control signal, described pulse signal enters into volume pump 4, volume pump 4 is made to work once, volume pump 4 discharges a part of liquid in liquid trap 1, along with the inflow of liquid, in liquid trap 1, the liquid level of liquid is greater than default liquid level threshold values, then volume pump 4 in work once, totalizer accumulates once again.After the one-time detection cycle completes, data processor obtains the accumulated value A in totalizer, and obtain the flow D of liquid in this sense cycle according to described accumulated value A, the volume pump 4 liquid volume B that once discharges and sense cycle C that works, wherein, D=A.B/C, then shows the flow D in this sense cycle by display.
