Abstract
The invention discloses a heating Pitot heat meter which comprises a Pitot flow meter, an inlet temperature sensor, an outlet temperature sensor and a heat integrating meter. The Pitot flow meter is used for measuring flow of liquid in a pipeline, the inlet temperature meter and the outlet temperature meter are used for respectively measuring the temperature of liquid at a liquid inlet end of the pipeline and the temperature of liquid at a liquid outlet end of the pipeline, a signal output end of the inlet temperature sensor and a signal output end of the outlet temperature sensor are connected with signal input ends of the heat integrating meter, the Pitot flow meter is provided with a flow integrating meter, and a flow signal output end of the flow integrating meter is connected with a signal input end of the heat integrating meter. The heating Pitot heat meter has the advantages that the heating Pitot heat meter is simple in structure, convenient to mount and low in purchasing cost; the Pitot flow meter is high in measurement precision which can generally reach the 1.0 level, is quite suitable for measuring heating heat of domestic consumers, is wide in liquid medium application range and is anti-blocking and anticorrosion, influence of measured media in the pipeline on the service life of the heating Pitot heat meter can be prevented, and the like.
Description
Technical field
The present invention relates to a kind of heating calorimeter, specifically relate to a kind of heating Pitot bar calorimeter being applicable to Home Heating and using.
Background technology
Northern China needs heating winter, in order to economize energy, reduces flue dust, and most of area is by heat supply network central heating.Heat energy is sold as a kind of commodity, needs charge, and the practice general at present receives heat supply expense by floor area of building, and this mode collecting heat supply expense is obviously irrational, should calculate according to the heat energy that user is actual.Automatically the instrument of heat accumulative is not do not have at present, the calorimeter of the kinds such as such as mechanical type, electromagnetic type, ultrasonic type has occurred, but because the price of these calorimeters is higher, precision is lower (general measure precision only reaches about 2%) and have influence on the reasons such as instrument serviceable life itself because of media problem measured in pipeline, so above-mentioned calorimeter does not temporarily also enter family, be only be applied on heat supply house steward.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of measuring accuracy is high, manufacturing cost is relatively low and can not be subject in pipeline measured medium influence to the heating Pitot bar calorimeter in instrument serviceable life itself.
For solving the problems of the technologies described above, a kind of heating Pitot bar calorimeter of the present invention, comprise the bi toba flow meter for measuring channel inner fluid flow, for the inlet temperature sensor of respectively measuring channel fluid intake end and fluid outlet fluid temperature (F.T.) and outlet temperature sensor and heat integrating instrument, described inlet temperature sensor is connected with the signal input part of this heat integrating instrument with the signal output part of outlet temperature sensor, described bi toba flow meter has flow integrator, the flow signal output terminal of this flow integrator is also connected with the signal input part of described heat integrating instrument.
Adopt the heating Pitot bar calorimeter of said structure, can bi toba flow meter be loaded on the pipeline of fluid intake end during use, described inlet temperature sensor and outlet temperature sensor are loaded on the pipeline of fluid intake end and fluid outlet respectively, bi toba flow meter can measure the flow of the fluids within pipes flowing through user, inlet temperature sensor and outlet temperature sensor can measure the temperature difference of the fluid of pipe head and endpiece, by the temperature difference of the fluid of pipe head and endpiece, combine the fluid flow flowed through again, the heat numerical value flowing through user can be calculated in described heat integrating instrument.Structure of the present invention is simple, easy for installation, purchase cost is low, because the measuring accuracy of described bi toba flow meter is high, generally reach 1.0 grades, therefore the heating-amount being applicable to very much domestic consumer is measured, due to the bi toba flow meter in the present invention, to adapt to fluid media (medium) in extensive range, has the features such as anti-blocking, anticorrosion, therefore also can not to be subject in pipeline measured medium influence to serviceable life of the present invention.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is the using state figure that a kind of heating Pitot of the present invention clings to when calorimeter is loaded on pipeline.
Embodiment
Show using state when a kind of heating Pitot bar calorimeter of the present invention is loaded on pipeline see Fig. 1, Fig. 1, in figure, left side is heating user 1, and the pipeline of heating user right has fluid intake end 2 and fluid outlet 3.A kind of heating Pitot bar calorimeter of the present invention, comprise the bi toba flow meter 10 for measuring channel inner fluid flow, for the inlet temperature sensor 20 of respectively measuring channel fluid intake end and fluid outlet fluid temperature (F.T.) and outlet temperature sensor 30 and heat integrating instrument 40, described inlet temperature sensor 20 is connected with the signal input part of this heat integrating instrument 40 with the signal output part of outlet temperature sensor 30, described bi toba flow meter 10 has flow integrator 11, the flow signal output terminal of this flow integrator 11 is also connected with the signal input part of described heat integrating instrument 40.
