Abstract
The utility model discloses a heat meter. The heat meter comprises an instrument box connected above a meter body, a water inlet pipe and a water outlet pipe which are connected at two sides of the meter body, the heat meter also comprises a thermocouple A and a thermocouple B, a hot terminal of the thermocouple A is positioned in the water inlet pipe, a hot terminal of the thermocouple B is positioned in the water outlet pipe, and cold terminals of the thermocouple A and the thermocouple B are respectively connected with the instrument box. The two thermocouples are employed to measure the water inlet temperature and water outlet temperature, detection information are sent to the instrument box to be compared, a water temperature difference is then obtained, the detection result is more accurate, and effective basis is provided for reasonable charging.
Description
Technical field
The utility model relates to a kind of calorimeter.
Background technology
Zone for central heating, calorimeter is a kind of instrument that realizes meterage, require its precision higher, to guarantee user and supplier's interests, its principle is to calculate the heat of consumption according to the water temperature difference that detects inflow and outflow user, adopted in the past the platinum thermometer to be measured, when water temperature differs hour, its measuring accuracy is difficult to meet the demands, prior art has the calorimeter that adopts thermocouple thermometer to measure water temperature difference, the hot junction of thermopair is connected with instrument case with cold junction, the hot junction of thermopair is measuring junction, the cold junction of thermopair is output terminal, this calorimeter that hot junction and cold junction all are connected to instrument case can't be measured at all.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of calorimeter, can solve the problem that the existing calorimeter that adopts the thermocouple measurement water temperature difference can't be used.
The utility model is achieved through the following technical solutions:
A kind of calorimeter, comprise the instrument case that is connected in table body upper end, and the water inlet pipe and the rising pipe that are connected in table body both sides, also comprise A thermopair and B thermopair, the hot junction of described A thermopair is arranged in water inlet pipe, the hot junction of described B thermopair is arranged in rising pipe, and the cold junction of described A thermopair and B thermopair is connected to instrument case.
The utility model advantage compared with prior art is:
Measure respectively the temperature of water inlet, water outlet by two thermopairs, detection information is sent into to instrument case and contrast the acquisition water temperature difference, testing result is more accurate, for reasonable fee provides effective foundation.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
A kind of calorimeter as shown in Figure 1, comprise the instrument case 1 that is connected in table body 2 upper ends, and the water inlet pipe 3 and the rising pipe 4 that are connected in table body 2 both sides, also comprise A thermopair 5 and B thermopair 7, the hot junction 6 of described A thermopair 5 is arranged in water inlet pipe 3, the hot junction 8 of described B thermopair 7 is arranged in rising pipe 4, and the cold junction of described A thermopair 5 and B thermopair 7 is connected to instrument case 1.
Claims (1)
1. a calorimeter, comprise the instrument case (1) that is connected in table body (2) upper end, and the water inlet pipe (3) and the rising pipe (4) that are connected in table body (2) both sides, it is characterized in that: also comprise A thermopair (5) and B thermopair (7), the hot junction (6) of described A thermopair (5) is arranged in water inlet pipe (3), the hot junction (8) of described B thermopair (7) is arranged in rising pipe (4), and the cold junction of described A thermopair (5) and B thermopair (7) is connected to instrument case (1).
