What are the advantages of thermal mass flow meters?

From the name of the thermal mass flow meter, we can see what this device is used for. After continuous improvement, this product has more and more functions. In order to let more people be familiar with it, the editor will introduce its basic information. If you want to know, let's take a look together, hoping to help you. Before operating the thermal mass flow meter, there are many points of knowledge that we need to understand, after all, many users are not very familiar with it. In fact, the thermal mass flow meter is designed based on the principle of thermal diffusion, and the instrument uses the constant temperature difference method to accurately measure the gas. Of course, when it is used, it has the advantages of small size, high degree of digitalization, convenient installation, and accurate measurement. The thermal mass flow meter has a simple composition and a wide range ratio, so it can measure gases with flow rates as high as 100 Nm/s and as low as 0.5 Nm/s. It can also be used for gas leak detection; it has good shock resistance, long service life, and a low failure rate; in addition, it is also necessary to know that the specific heat capacity of the gas of the thermal mass flow meter changes with pressure and temperature, and the change is not large nearby; installation and maintenance are simple, and under the condition that the site allows, uninterrupted installation and maintenance can be realized.

Introduction to the working principle of thermal mass flow meters

Introduction to the working principle of thermal mass flow meters

What is a thermal mass flow meter? Originating in the United States, thermal mass flow meters (TMF) are generally used for gas measurement in high-precision, trade settlement, or difficult-to-measure environments. Compared with traditional instruments, thermal mass flow meters have many advantages in measurement accuracy and maintenance, and are widely used in various industries such as thermal power, chemical industry, and oil and gas. Since its introduction to the general factory, it has performed well in gas flow measurement and has certain applicability. A thermal mass flow meter is a thermal pneumatic instrument used to measure and calculate the temperature of a fluid medium. It mainly consists of a differential pressure transmitter, an electromagnetic flow converter, etc. It can directly display or record flow rate, liquid level, and density values, and can be connected to a host computer to realize remote data transmission. Thermal mass flow meters are suitable for measuring the average temperature rise of working media in various viscous systems such as steam and air, such as feeding in petrochemical production, powder materials in dust removal pipelines, coal slurry pipelines, etc. Thermal mass flow meters have a simple structure and are easy to maintain. They can be installed and used without standard parts, so they are widely used in various fields of the national economy. Working principle of thermal mass flow meter A thermal mass flow meter is a pipeline filled with metal or other materials with high density and good conductivity as a temperature measuring medium. When the measured medium passes through

Basic introduction to thermal mass flow meters

Basic introduction to thermal mass flow meters

Many people still do not understand the basic information about thermal mass flow meters. Therefore, as a manufacturer of mass flow meters, it is necessary for us to briefly explain that thermal mass flow meters are instruments that measure gas flow using the principle of thermal diffusion. The sensor consists of two reference-grade thermistors (RTD). Of course, during operation, one of them is a velocity sensor RH...
