Proline T-Mass I 300 Thermal Mass Flowmeter
Brand: Endress+HauserProline T-Mass I 300 Thermal Mass Flowmeter
Brand: Endress+Hauser

The patented sensor design of t-mass I provides unprecedented measurement stability in thermal insertion mass flow measurement. It compensates in real time for changes of process conditions: temperature, pressure, flow direction and gas type. Its compact transmitter offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. Heartbeat Technology enables measurement reliability and compliant verification.
