Description

1. Introduction to Gas Roots/Wheel Flow Meter MT-F100GW

The Gas Roots/Wheel Flow Meter MT-F100GW is an advanced instrument designed for precise measurement of gas flow, integrating temperature, pressure, and volumetric correction into one compact unit. Its intelligent sensors allow real-time compensation for variations in pressure and temperature, providing accurate readings for industrial gas applications.

This flow meter is widely used in natural gas distribution, petrochemical plants, and any process requiring reliable gas metering with high accuracy. Its compact design ensures easy installation and long-term operation, making it ideal for both on-site and remote applications.

2. Working Principle

The MT-F100GW operates using a mechanical Roots or wheel mechanism that measures the volumetric flow of gas. As the gas passes through the meter, the rotation of the wheels or rotor is proportional to the volume of gas flowing. Integrated sensors for pressure and temperature allow the meter to perform automatic compensation and apply the necessary correction factors for compression and environmental changes.

This ensures highly accurate readings even under fluctuating pressure and temperature conditions. The intelligent design integrates all sensors and electronics into a single unit, reducing the need for external devices and simplifying installation.
