Application
* The measuring principle is unaffected by gas composition
* Accurate measurement of natural and process gas in the chemical as well as oil and gas industries. Device properties:
* Direct measurement: flow, pressure & temperature
* Wetted parts: titanium / 316L
* Maximum measuring accuracy: 0.5 %
* Remote version with up to 4 I/Os
* Backlit display with touch control and WLAN access
* Standard cable between sensor and transmitter
Benefits
* 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
* 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
