Esdun Industrial 
The Rosemount 2051CFC Integral Orifice Plate Flow Meter offers dependable flow measurements. This flow meter is engineered with an integral orifice primary element, which is provided in a meter run and facilitates accurate flow measurement in small line sizes (0.5 – 1.5 in. or 15 – 40 mm). This safety-certified transmitter also features a local operator interface (LOI) for easy field commissioning. This device is offered with multiple communication protocols, including WirelessHART.
