Abstract
The invention discloses a heat meter with a pressure measuring function. On the basis of the existing heat meter, two pressure sensors are added, wherein, one pressure sensor is arranged on the water inlet pipe section of the heat meter, and the other pressure sensor is arranged on the water outlet pipe section thereof and is connected with a calculator by a lead wire. When the water pressure of the current pipe section changes, the pressure sensing resistance value of the pressure sensor also changes so as to realize a pressure monitoring function. The heat meter has all functions of the common heat meter, can test the pressure of the current pipe section and integrates the functions of flow measurement, temperature measurement, heat measurement, pressure measurement and the like into a whole.
Description
Technical field:
The present invention relates to a kind of calorimeter, refer to a kind of calorimeter of tool pressure measuring function especially.
Background technology:
Existing calorimeter structure, as shown in Figure 1, comprise counter 1, ultrasonic sensor 2,3 and temperature sensor 4,5.Ultrasonic sensor 2 is connected on the junction block 7 through lead 6; Ultrasonic sensor 3 is connected on the junction block 7 through lead 8; Lead 6 gathers into a bus 9 at last with lead 8 and is connected with counter 1, and temperature sensor 4 is installed on the water inlet segment 10, can measure the temperature of water inlet end water.Temperature sensor 5 spiral shells are solid in the perforate of water outlet pipeline section 11, can measure the temperature of water end (W.E.) water, thereby can calculating into, water go out water temperature difference.And; This calorimeter is according to the flow direction of the water of the water outlet pipeline section 11 of flowing through; Install ultrasonic sensor 2,3 respectively at the upstream and downstream of water outlet pipeline section 11, the length in the transmission time that is produced when receiving according to this two ultrasonic sensor 2,3 is different, and can further calculate the flow of current water.According to the water temperature difference of calculating, calculate again, demonstrate the calorie value that thermal liquid discharged or absorbed to exporting from inlet through counter 1.
Above-mentioned calorimeter meter only possesses flow, temperature, reaches the calorimetry function; But do not have pressure measuring function, like its instrument or mechanism that needs to increase in addition tool pressure test function, its cost is than higher; Install and also can expend more time and cost, improved necessity is still arranged.
Summary of the invention:
Technical matters to be solved by this invention is: to the deficiency of above-mentioned prior art, a kind of calorimeter of tool pressure measuring function is provided, it can not only measure flow, temperature and the heat of the water of current pipe section, can also measure the pressure of water in the current pipe section.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of calorimeter of tool pressure measuring function; Comprise counter, two ultrasonic sensors, reach two temperature sensors; This two ultrasonic sensor all is installed on the water outlet pipeline section of calorimeter and through lead and is connected with counter, and this two temperature sensor is installed in respectively and also passes through lead on water inlet segment and the water outlet pipeline section of calorimeter and be connected with counter, and be characterized in: this calorimeter also comprises two pressure transducers; Wherein a pressure transducer is installed on the water inlet segment of this calorimeter, and is connected with counter through lead; Another pressure transducer is installed on the water outlet pipeline section, and is connected with counter through lead.
Compared with prior art; The invention has the beneficial effects as follows: this calorimeter is on the basis of existing calorimeter; Through installing pressure transducer on the pipeline section of calorimeter; When changing appearred in hydraulic pressure, the force-sensing resistor resistance of pressure transducer also can change thereupon, thereby realized the function of pressure monitoring.This calorimeter not only possesses all functions of ordinary hot scale, and can test the pressure in the current pipe section, and functions such as afflux measurement amount, temperature survey, calorimetry, pressure survey are in one, and pressure test need not extra installation, has practiced thrift cost greatly.
Description of drawings:
Fig. 1 is the structural representation of existing calorimeter.
Fig. 2 is a structural representation of the present invention.
Embodiment:
Referring to shown in Figure 2, calorimeter of the present invention comprises counter 1, two ultrasonic sensors 2,3, two temperature sensors 4,5 and two pressure transducers 12,13.Counter of the present invention, ultrasonic sensor, and the structure of temperature sensor identical with position annexation and prior art, repeat no more at this.Need to prove that the present invention is on the basis of existing calorimeter, has additional two pressure transducers 12,13 again.Wherein a pressure transducer 12 is installed on the water inlet segment 10, and is connected with counter 1 through lead 14; Another pressure transducer 13 is installed on the water outlet pipeline section 11, and is connected with counter 1 through lead 15.This pressure transducer market is on sale.
Because the function that pressure transducer possessed; When changing appearred in water flow pressure in the pipeline section, the force-sensing resistor value of pressure transducer can change thereupon, thereby; The pressure that this calorimeter just can be measured each time period, water inlet end, water side changes; And because be connected with counter through lead, and an exportable pressure signal to counter, and demonstrate hydraulic pressure value on the Displaying Meter in counter.Thereby, on the calorimeter basis, realize functions such as water-pressure survey, calculating and demonstration, effectively with flow, integrating, pressure sensing, be shown in one, have little power consumption, characteristics such as volume is little.
