Proline Prosonic Flow G 300 ultrasonic flowmeter

Ultrasonic flow

Highly robust gas specialist for fluctuating process conditions with compact, easily accessible transmitter.
Flexible device with user-definable gas mixtures for demanding measuring tasks.
Accurate measurement of natural and process gas in the chemical as well as oil and gas industries.

Maximum reliability even with humid or wet gas – sensor design insensitive to condensate. High-performance process control – real-time pressure- and temperature-compensated values. Efficient solution – multivariable, no pressure loss.
Direct measurement: flow, pressure & temperature. Wetted parts: titanium / 316L. Maximum measuring accuracy: 0.5 %.

Full access to process and diagnostic information – numerous, freely combinable I/Os. Reduced complexity and variety – freely configurable I/O functionality. Integrated verification – Heartbeat Technology.
Compact dual-compartment housing with up to 3 I/Os. Backlit display with touch control and WLAN access. Remote display available.
