Esdun Industrial 
Easy-to-install and designed to deliver industry-standard performance, the Rosemount 2051CFC Compact Orifice Flow Meter offers dependable flow measurements. Built with either a compact orifice plate, a patented 4-hole conditioning plate, or averaging pitot tube, this flow meter provides measurements for closed loop control, general purpose monitoring, and custody transfer applications. Available in line sizes up to 12 in. (300 mm), this primary element is designed for gas, liquid and steam service and operates well in harsh process conditions. This device is offered with multiple communication protocols, including WirelessHART.
