Thermal gas mass flow meter design based on the principle of thermal diffusion to the production of the products are widely used in steel mills, coking plants, petroleum, chemical, thermal, medical, thermal power plants, environmental protection industry. Thermal gas mass flow meter is a real, direct mass flow meter, the user does not have the pressure and temperature compensation. The instrument has no moving parts, small pressure loss range than the width, high accuracy, high reliability, easy to install, easy to operate. Installation of various types, pipeline, plug-in for easy selection

 Range width: 100:1 
 Repeatability: 0.2% of the wide tube side than 
 Sensor difficult to plug, available on-line plug 
 Maximum pressure tall 10MPa, with a variety of output of 4-20 mA, RS232, the RS485, etc.. 

 Thermal Gas Mass Flowmeter works: 
 Thermal Gas Mass Flowmeter is the heat conduction technology, gas mass flow measurement. Flowmeter probe with two platinum resistance sensing element (see Figure 1), they are placed in the fluid, one of the heating power P, its temperature rose to T-1, and the other is not heated, used to monitor medium temperature is set to the T2. So between the two sensing elements of temperature difference △ T = T1-T 2. When flow is zero, △ T, with the mass flow rate Q increases, the heat of the sensing element T is taken away, T1 decreased △ T decreased. Therefore, the above heating power P, the temperature difference △ T and mass flow rate Q will produce a certain relationship. Can be expressed as: 
 P / ΔT = K1 + K2F (Q) K3 .................. (1) 
 Where K1, K2, K3 is related to the physical properties of the gas constant. 
 By measuring the heating power P can be seen from the above equation, changes in the temperature difference △ T can be obtained mass flow rate Q. To simplify the problem, the actual work is the heating power (P) or temperature difference △ T remains unchanged. The former is called the constant power type, which is called a constant temperature differential. HH-The LQ thermal gas mass flow meter, depending on the requirements of the election in which a way to work.
