Abstract
The invention mainly discloses an ultrasonic wave heat testing device which comprises a temperature sensor I and a temperature sensor II, a pair of ultrasonic transceivers arranged in medium, a controller unit for processing process data, and a display apparatus, wherein the temperature sensor I and the temperature sensor II are respectively arranged at a water outlet position and a water return position; the temperature sensor I, the temperature sensor II and the ultrasonic transceivers are connected to the input end of the controller unit, and the controller unit which is provided with calculation program in the internal part calculates according to the received data at the input end, and feeds back the result to the display apparatus. According to the ultrasonic wave heat testing device, heat (cold) quantity consumed by a user in a heat supply (cold supply) system is accurately measured, and the ultrasonic wave heat testing device is stable to use.
Description
Technical field
The present invention relates to the technical field of meter fluid heat, special and a kind of ultrasonic heat measures trial assembly and is equipped with the pass.
Background technology
Calorimeter be in the heat supply system by the crucial instrument and the important evidence of heat metering charge, technical indicators such as its measuring accuracy, job stability are very important.With heat (cold) water is the user was consumed in central heating (cooling) system of media heat (cold) amount, relevant with heat (cold) discharge and confession, the braised value of backwater.Along with China installs calorimeter and carries out the popularization by family meterage work the covil construction of central heating, the calorimeter of household metering has also welcome an extraordinary developing period.Calorimeter has types such as mechanical type and ultrasonic type, and ultrasonic calorimeter is one of developing direction of heating system.Ultrasonic calorimeter product on the present home market, its flow measurement stability and measuring accuracy are not good enough, and metering is accurately when just installing; Deviation will appear after after a while; To these defectives, the inventor designs a kind of ultrasonic heat measurement trial assembly and puts, and this case produces thus.
Summary of the invention
The purpose of this invention is to provide a kind of ultrasonic heat measurement trial assembly and put, realize heat (cold) amount that the user consumed in accurate measurement heat supply (cooling) system, use stable.
In order to achieve the above object, the present invention realizes through following technical scheme:
A kind of ultrasonic heat measures trial assembly and puts, and comprises the temperature sensor one and the temperature sensor two that are separately positioned on water outlet place, backwater place, is laid in a pair of ultrasonic transmitter-receiver in the medium, and the controller unit of handling deal with data, Displaying Meter; Described temperature sensor one, temperature sensor two and ultrasonic transmitter-receiver are connected to the input end of controller unit; Set inside has the controller unit of calculation procedure to calculate according to the data that input end receives, and the result is fed back on the Displaying Meter.
Described ultrasonic transmitter-receiver is placed in opposite directions, alternately receives and dispatches ultrasound wave.
Described controller unit is a single-chip microcomputer.
After adopting such scheme, the present invention has many beneficial effects:
Can detect the temperature of water outlet and backwater among the present invention through two temperature sensors; Draw temperature gap; And cooperate ultrasonic transmitter-receiver to come test fluid speed again; Thus outflow, and these data all be sent in the controller unit calculate, feed back on the Displaying Meter after calculating accurate calorie value.The present invention is simple in structure, and is easy for installation, and computational accuracy is accurate, and the life-span is long, helps independently installing and using of each user.
Description of drawings
Fig. 1 is the scheme of installation of preferred embodiment of the present invention;
Fig. 2 connects synoptic diagram for the module of preferred embodiment of the present invention.
Embodiment
In conjunction with accompanying drawing, preferred embodiment of the present invention is explained further details.
A kind of ultrasonic heat measures trial assembly and puts, and mainly comprises temperature sensor 1 and temperature sensor 22, a pair of ultrasonic transmitter- receiver 31,32, controller unit 6, display instrument 7.
In the pipeline of medium circulation; Be laid with a pair of ultrasonic transmitter-receiver of placing in opposite directions 31,32; Both alternately receive and dispatch ultrasound wave, come to measure indirectly flow rate of fluid, a kind of indirect measurement that comes calculated flow rate by flow velocity through the following current and the adverse current propagation time difference of observation ultrasound wave in medium; This algorithm is not done here and is given unnecessary details originally as routine techniques general knowledge in the ultrasonic technology field.
Functional module of the present invention connects as shown in Figure 2, and temperature sensor 1, temperature sensor 22, a pair of ultrasonic transmitter- receiver 31,32 are connected on the input end of controller unit 6, connects display instrument 7 on the output terminal of controller unit 6.
Present embodiment middle controller unit 6 adopts the single-chip microcomputer form, and portion has calculation procedure within it.Because the formula
of heat; The temperature difference that
supplies water for medium and backwater is drawn; Can calculate from both temperature differences of temperature sensor 1, temperature sensor 22; And
is the mass of medium that expression is flow through, and can come to draw indirectly through detected flow velocity.Specific as follows:
; Wherein
is Media density;
is the sectional area of the pipeline of flowing through;
is velocity of medium, and
is flowing time.
thus; This formula calculating is enrolled to controller unit 6 internal processes; When the resulting data of actual detected are input in the controller unit 6; Just can directly calculate accurate result, and this result's feedback is shown on the display instrument 7.
The foregoing description only is used to the inventive concept of the present invention of explaining, but not to the qualification of rights protection of the present invention, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
