Endress+Hauser 6I3BL1

Thermal mass flowmeter

6I3BL1 is one of the configurations in the Proline t-mass I 300 series—a thermal mass flow meter for gases. It is an insertion-type sensor with drift resistance, a compact transmitter unit, and Heartbeat diagnostics. The device is designed to measure gas mass directly, eliminating the need for pressure and temperature correction in some applications.

This flow meter is suitable for large-diameter water pipes and air ducts where minimizing pressure loss and ensuring stable measurements is essential.
