Abstract
The utility model mainly discloses a supersonic heat measuring device comprising a temperature sensor 1, a temperature sensor 2, a pair of supersonic transceivers disposed in a medium, a controller unit used for processing data, and a display instrument. The temperature sensor 1 and the temperature sensor 2 are disposed at a water outlet and a water return port, respectively. The temperature sensor 1, the temperature sensor 2, and the supersonic transceivers are connected with the input end of the controller unit. The controller unit internally equipped with a calculating program performs calculation according to data received by the input end and gives a feedback of result to the display instrument. The supersonic heat measuring device achieves accurate measurement of heat amount (cold amount) consumed by users in a heat supply (cold supply) system and has stable performance.
Description
Technical field
The utility model relates to the technical field of meter fluid heat, and is special relevant with a kind of ultrasound wave heat test device.
Background technology
Calorimeter be in the heat supply system by Complete set of instrument and the important evidence of heat metering charge, the technical indicators such as its measuring accuracy, job stability are very important.Take heat (cold) water heat (cold) that the user was consumed in central heating (cooling) system of medium amount, with heat (cold) discharge and relevant for, the braised value of backwater.Along with China installs calorimeter and carries out the popularization of pressing family meterage work the covil construction of central heating, the calorimeter of household metering has also welcome an extraordinary developing period.Calorimeter has the types such as mechanical type and ultrasonic type, and ultrasonic calorimeter is one of developing direction of heating system.Ultrasonic calorimeter product on the domestic 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, for these defectives, the inventor designs a kind of ultrasound wave heat test device, and this case produces thus.
The utility model content
The purpose of this utility model provides a kind of ultrasound wave heat test device, realizes heat (cold) amount that the user consumes in accurate measurement heat supply (cooling) system, uses stable.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of ultrasound wave heat test device 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 processing 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, the controller unit that inside is provided with calculation procedure calculates according to the data that input end receives, and with result feedback to Displaying Meter.
Described ultrasonic transmitter-receiver is placed in opposite directions, alternately receives and dispatches ultrasound wave.
Described controller unit is single-chip microcomputer.
After adopting such scheme, the utlity model has many beneficial effects:
Can detect by two temperature sensors the temperature of water outlet and backwater in the utility model, draw temperature gap, and cooperate again ultrasonic transmitter-receiver to come test fluid speed, get thus outflow, and these data all are sent in the controller unit calculate, feed back on the Displaying Meter after calculating accurate calorie value.The utility model is simple in structure, and is easy for installation, and computational accuracy is accurate, and the life-span is long, is conducive to independently installing and using of each user.
Description of drawings
Fig. 1 is the scheme of installation of the utility model preferred embodiment;
Fig. 2 is the module connection diagram of the utility model preferred embodiment.
Embodiment
By reference to the accompanying drawings, preferred embodiment is described in further details to the utility model.
A kind of ultrasound wave heat test device 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 31,32 of placing in opposite directions, both alternately receive and dispatch ultrasound wave, indirectly measure the flow velocity of fluid by observing the co-current flow and counter-current flow propagation time difference of ultrasound wave in medium, come a kind of indirect measurement of calculated flow rate by flow velocity.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 utility model connects as shown in Figure 3, 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 section has calculation procedure within it.Because the formula of heat
,
For medium supplies water and the drawn temperature difference of backwater, can calculate from both temperature differences of temperature sensor 1, temperature sensor 22, and
Be the mass of medium that expression is flow through, can indirectly draw by the flow velocity that detects.Specific as follows:
, wherein
Be Media density,
Be the sectional area of the pipeline of flowing through,
Velocity of medium,
Be flowing time.Thus
, this formula calculated enroll to controller unit 6 internal processes, when detecting resulting data, reality is input to controller unit 6 when interior, and just can directly calculate accurate result, and this result feedback is shown on the display instrument 7.
Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
