Flowmeter Configurations eee June 2007 Overview Operating the PanaFlow MV The GE Sensing Series MV80 In Line and the Series MV82 Insertion PanaFlow MV Vortex Flowmeters provide a reliable solution for process flow measurement From a single entry point in the pipeline PanaFlow MV meters offer precise measurements of mass or volumetric flow The velocity sensor reduces the effects of pipeline vibration by incorporating a unique piezoelectric element that senses the vortex frequency To extend range ability at the low end of flow the meter s smart electronics calculates the Reynolds number Re based on constant values of fluid density and viscosity stored in memory and automatically corrects for any non linearity down to Re 5 000 PanaFlow MV digital electronics allows reconfiguration for most gases liquids and steam The instrument is loop powered 12 to 36 VDC with two output signals The pulse output signal is proportional to volumetric flow rate the analog linear 4 20 mA signal offers your choice of volumetric flow rate or mass flow rate The mass flow rate is based on a constant value for fluid density stored in the instrument s memory The local key pad display provides instantaneous flow rate in engineering units or to talized flow Figure 1 1 In Line Vortex Multi Parameter Mass Flowmeter The Series MV80 and MV82 P
