Thermal Mass Flowmeters Introduction

Thermal mass flow meter is a flow meter that can detect the mass flow of gas without temperature and pressure compensation.


Thermal Mass Flow Meter Unaffected by changes in viscosity, density, temperature, or pressure. Thermal mass flow meters are designed based on the principle of thermal diffusion.


Including natural gas, coal gas, liquefied gas, flare gas, argon, carbon dioxide, and other mixed gas flow measurement.

Thermal Mass Flowmeters Features


            

    • Directly measure the mass flow of fluid in the pipeline

      • The measurement accuracy is high and the repeatability is good. It can directly measure the fluid mass flow in a large range

    • High measurement accuracy

      • The mass flow measurement accuracy of this flowmeter is 0.2 level

    • Stable and reliable work

      • There are no obstacles and moving parts in the fluid measuring tube, so it has high reliability and long life.

    • Adapted fluid medium surface width

      • In addition to uniform fluids with general viscosity, it can also measure high-viscosity fluids (honey, oil slurry, etc.).

      • It can measure not only the fluid parameters of a single solution, but also multiphase flow.

      • Whether the medium is laminar or turbulent, it does not affect its measurement accuracy.

    • Wide application environment

      • It is suitable for petrochemical, chemical, metallurgical, pharmaceutical, paper, food, energy and environmental protection industries.

      • In the process of inspection and control and custody transfer measurement and other occasions.

      • Has been widely used,

    • Multiple real-time online measurement and control functions

      • In addition to mass flow, the density and temperature of the fluid can also be directly measured.

      • The intelligent flow transmitter can provide a variety of parameter display and control functions. It is a multi-function flow measurement and control instrument.

    • Good scalability

      • The company can design and manufacture mass flow meters with special specifications and special functions according to user needs.

      • It can also perform remote monitoring operations.

Thermal Mass Flowmeters Specification

Thermal mass flow meters are used almost entirely for gas flow applications. As the name implies, the meters use heat to measure flow, and they introduce heat into a flowing stream and measure how much heat dissipates using one or more temperature sensors. This method works best with gas mass flow measurement.
