Overview
Liaoning Xinruipeng Environmental Protection Pipe Section Thermal Gas Mass Flow Meter is designed based on the principle of thermal diffusion (constant temperature difference method), which differs from the drawbacks of traditional volumetric flow meters that require additional temperature and pressure compensation. It can directly measure the mass flow rate of gas, improving measurement accuracy and efficiency from the root. The core working mechanism is to utilize the thermal conductivity characteristics of gas flow and achieve flow detection through two accurately matched temperature sensors - one is a heating probe and the other is a temperature measurement probe. The instrument is controlled by a circuit to maintain a fixed temperature difference between the two (usually set at 50 ℃).

1、 Core Measurement Principles
Liaoning Xinruipeng Environmental ProtectionPipe section thermal gas mass flowmeterBased on the principle of thermal diffusion (constant temperature difference method), this design differs from the drawbacks of traditional volumetric flow meters that require additional temperature and pressure compensation. It can directly measure the mass flow rate of gases, improving measurement accuracy and efficiency from the root. Its core working mechanism is to utilize the thermal conductivity characteristics of gas flow, and achieve flow detection through two accurately matched temperature sensors: one is a heating probe and the other is a temperature measurement probe. The instrument is controlled by a circuit to maintain a fixed temperature difference between the two (usually set at 50 ℃).
When gas flows through the pipeline section, it will take away the heat on the surface of the heating probe. To maintain a fixed temperature difference, the heating probe needs to consume additional electrical energy, and the electrical power consumed is precisely proportional to the mass flow rate of the gas. The instrument is equipped with a high-precision signal processing module, which collects real-time data on changes in electrical power. Combined with self-developed AI algorithms, it automatically corrects errors caused by factors such as gas composition and environmental temperature, quickly converts gas mass flow rate, and outputs accurate and stable measurement results without manual intervention.
This product is optimized for environmental monitoring scenarios and uses corrosion-resistant coating to treat the sensing probe. It can withstand corrosive substances such as sulfides in flue gas and effectively solve the industry pain points of sensor damage and measurement drift under complex working conditions, ensuring long-term stable operation. At the same time, its structure without throttling elements almost does not generate pressure loss, does not affect the normal flow of gas in the pipeline, and is suitable for various complex working conditions.
