Mass Flowmeter

Mass Flowmeter

The Mass Flow Meter is based on advanced Coriolis technology, providing direct and highly accurate measurement of mass flow without the need for temperature or pressure compensation.

Unlike conventional flow meters, it measures true mass flow while simultaneously monitoring mass flow, volumetric flow, density, and temperature in a single device. Measurement accuracy remains stable regardless of changes in temperature, pressure, or fluid properties.

Widely used in LNG and LPG systems, natural gas metering, oil & gas, chemical processing, energy, food, and pharmaceutical industries, the Coriolis Mass Flow Meter is ideal for custody transfer, process control, and high-precision industrial flow measurement applications.

Product Details

When fluid flows through the vibrating measuring tubes, Coriolis forces proportional to the mass flow are generated. These forces cause a slight phase shift (twist) in the tubes.

Sensors detect this phase difference, and the transmitter processes the signal to directly calculate:

  • Mass Flow Rate

  • Volume Flow Rate

  • Density

  • Temperature

This direct mass measurement ensures superior accuracy and stability under varying process conditions.
