Proline t-mass 65F with flanges for industrial gases and compressed air

The Thermal Flow Measuring Principle

High-performing flowmeter with intelligent and dynamic adaptation to changing process conditions

The t-mass 65F inline device is specially designed for the direct mass flow measurement of industrial gases and compressed air. With a turndown of typically 100:1 it can measure accurately operational flow rates and off line leakage. The integrated gas engine allows the customer to configure the device for 20 freely selectable gases.
