Summary
A thermal mass flow meter is a new type of high-temperature, low-pressure detection instrument, widely used in the petroleum, aerospace, metallurgy, food, and papermaking industries.
Thermal Mass Flow Meter It features a well-designed, high-performance temperature measurement and control system, and is equipped with an advanced intelligent digital display; it can directly input the mass or material density of the hot fluid.
Working principle of thermal mass flow meter: When the measured medium is high-temperature, high-pressure, or highly corrosive, high-temperature resistant materials must be used. When using this type of flow meter, care should be taken to prevent pipe blockage and scaling. When a phase change occurs in the organic vapor in the measured medium, due to the liquid itself not being able to withstand the drastic changes in pressure and temperature, a negative pressure zone proportional to atmospheric pressure is generated. This creates a vacuum state, resulting in a certain static pressure in the transmission component (called the diffusion tube), converting the total mass over that distance into displacement quantities in the form of density ρ and rate ρ. The value can be directly displayed or automatically recorded and output by devices such as digital integrators and printing recorders. Thermal Mass Flow Meter It is one of the most advanced and high-precision flow monitoring devices currently available.
A thermal liquid flow meter is a measurement instrument based on French technology, with advantages such as reliable accuracy and simple installation. It is suitable for high-temperature, corrosive, and non-conductive media, and is also widely used in the chemical, petroleum, and metallurgical industries for measuring the flow rate and pressure of gaseous or vapor media. The functional characteristics of a thermal mass flow meter are its wide measurement range, high accuracy, simple structure, and reliable durability.
