2. Principle and classification of heat meters
The meter that records how much heat you use is naturally a heat meter. Today we are going to talk about the relevant knowledge of heat meters. Many things in daily life use a heat meter, such as our air conditioner. However, it uses a (cold) heat meter, and the principle and structure of a (cold) heat meter are actually the same as that of a heat meter. Heat meters can be used in thermal companies, where they charge based on the amount of heat used and the relevant price levels set by the pricing department. Therefore, the accuracy required for heat meters will be relatively high. Lets learn about the relevant knowledge of the principle of heat meters together with me. The principle of a heat meter is to install a temperature sensor with an upward pipe through which the heat carrying fluid passes, and a downward pipe should also be installed. Install the flowmeter at the inlet of the fluid or above the reflux pipe. At this point, a pulse signal will be emitted by the flow meter, and this pulse signal is proportional to the flow meter. At this time, the temperature sensor will have an analog signal that displays the temperature level. The integrator uses an integration formula to calculate the amount of heat received by the heat exchange system, but it also collects signals from the flow rate and temperature sensor. Classification of heat meters: The flow meter structure of heat meters also differs in principle, and can be divided into mechanical, electromagnetic, and ultrasonic types.
1、 Mechanical heat meters come in both single stream and multi stream configurations. The meaning of a single stream meter is a mete

2、 The principle of ultrasonic heat meter is that ultrasonic waves can propagate in fluids, and the difference between the speed of propagation along the water flow and the speed of propagation against the water flow is used to calculate the fluid velocity, and then obtain the fluid flow rate. However, there are two forms of ultrasonic heat meters. One is direct type, and the other is reflective type.
3、 Electromagnetic heat meters have a very high cost because they also require an external power supply, so there are very few heat meters that use this type of flow meter. Divided by technical structure
1. Integrated heat meter refers to the three components of a heat meter (accumulator, flow meter, temperature sensor), in which two or more parts are theoretically (rather than formally) inseparable and combined together. For example, the accumulator and flow meter of the standard core type (non-magnetic electronic type) heat meter in mechanical heat meters cannot be interchanged arbitrarily, and only the overall measurement can be carried out during calibration.
2、 The three parts of a combined heat meter can be separated and replaced with each other in products of the same model. During calibration, each component ca
