Problems solved by technology

[0003] The above-mentioned heat meters only have flow, temperature, and heat measurement functions, but do not have pressure measurement functions. If they need to add additional instruments or mechanisms with pressure test functions, the cost is relatively high, and the installation will consume more time and cost. , there is still room for improvement

Embodiment Construction

[0009] see figure 2 As shown, the heat meter of the present invention includes a calculator 1, two ultrasonic sensors 2, 3, two temperature sensors 4, 5 and two pressure sensors 12, 13. The structure and position connection relationship of the calculator, the ultrasonic sensor, and the temperature sensor of the present invention are the same as those of the prior art, and will not be repeated here. It should be noted that the present invention adds two pressure sensors 12 and 13 on the basis of the existing heat meter. One of the pressure sensors 12 is installed on the water inlet pipe section 10 and connected to the calculator 1 through a wire 14 ; the other pressure sensor 13 is installed on the water outlet pipe section 11 and connected to the calculator 1 through a wire 15 . The pressure sensor is commercially available.

[0010] Due to the function of the pressure sensor, when the pressure of the water flow in the pipe section changes, the pressure sensing resistance v...

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: [0001] The invention relates to a heat meter, especially a heat meter with pressure measurement function. Background technique: [0002] Existing heat meter structures such as figure 1 As shown, it includes a calculator 1, ultrasonic sensors 2, 3 and temperature sensors 4, 5. The ultrasonic sensor 2 is connected to the terminal block 7 through the wire 6, the ultrasonic sensor 3 is connected to the terminal block 7 through the wire 8, the wire 6 and the wire 8 are finally combined into a bus 9 and connected to the calculator 1, and the temperature sensor 4 is installed in the water inlet On the pipe section 10, the temperature of the water at the inlet end can be measured. The temperature sensor 5 is screwed in the opening of the water outlet pipe section 11, and can measure the temperature of the water at the water outlet, thereby, the temperature difference between the inlet and outlet water can be calculated. And, according to the flow direction of the...
