Esdun Industrial 
Featuring industry-standard performance, the Rosemount 2051CFA Annubar Flow Meter provides dependable flow measurements via mulitple communication protocols including WirelessHART technology. The patented Annubar sensor design is able to deliver accuracy over a wide flow range, maintain a small profile in the pipe, and provide flow and pressure measurements via a signal pipe penetration. This safety-certified flow meter is engineered with a local operator interface (LOI) for field commissioning.
