Proline t-mass I 500
thermal mass flowmeter

Thermal

Insertion flowmeter with long-term stability as remote version with up to 4 I/Os.
Flexible, convenient programming based on 21 standard gases or freely definable gas mixtures thereof.
Measurement of utility and process gases as well as gas mixtures in circular piping or rectangular ducts.

High level of process control – premium measurement accuracy and repeatability. Reliable monitoring – detection of process disturbances and reverse flow. Flexible installation – suitable for large dimensional range and circular pipes or rectangular ducts.
Insertion version for DN 80 to 1500 (3 to 60"). Bidirectional measurement; high measuring performance. Patented drift-free sensor with SIL 2.

Full access to process and diagnostic information – numerous, freely combinable I/Os and fieldbuses. Reduced complexity and variety – freely configurable I/O functionality. Integrated verification – Heartbeat Technology.
Remote version with up to 4 I/Os. Backlit display with touch control and WLAN access. Standard cable between sensor and transmitter.
