The Emerson 3414 CPU is mainly used in Rosemount SeniorSonic 3414 four - path gas ultrasonic flow meters. It is a Type 4 CPU module that can increase input/output, with up to six frequency or digital outputs.
This CPU is applicable to pipeline diameters ranging from DN100 to DN1050 (4 - in to 42 - in). It is designed for gas measurement, with an accuracy of ±0.1% of the reading relative over the entire flow calibration range and a repeatability of ±0.05% of the reading for 5 to 100 ft/s (1.5 to 30.5 m/s). The rated velocity is up to 30 m/s (100 ft/s), and the over - range performance of some calibers exceeds 38 m/s (125 ft/s). It has a wide operating temperature and pressure range, and the materials are carbon steel and stainless steel. With it, the flow meter can quickly detect the dynamic changes of flow, reducing measurement uncertainty
