- Page 5 Always remove main power before disassembling any part of the mass flow meter. Caution! Calibration must be performed by qualified personnel. Sierra Instruments, Inc., strongly rec- ommends that you return your flow meter to the factory for calibration. In order to achieve accurate and repeatable performance, the flow meter must be in- stalled with the specified minimum length of straight pipe upstream and downstream of the flow meter’s sensor head.

Page 7: Chapter 1 Introduction
Chapter 1 Introduction Chapter 1 Introduction Innova-Flo™ Vortex Flow Meters The Sierra Instruments’ Series 220 In-Line and the Series 221 Insertion Innova-Flo™ Vortex Flow Meters provide a reliable solution for process flow measurement. From a single entry point in the pipeline, Innova-Flo meters offer precise measurements of mass or volumetric flow. -
Page 8: Note And Safety Information
Receipt of System Components When receiving a Sierra flow meter, carefully check the outside packing carton for damage incurred in shipment. If the carton is damaged, notify the local carrier and submit a report to the factory or distributor. Remove the packing slip and check that all ordered components are present. -
Page 9: How The Innova-Flo Vortex Flow Meter Operates
How the Innova-Flo Vortex Flow Meter Operates Figure 1-1. Series 220 In-Line Vortex Flow Meter ™ Sierra Series 220 and 221 Innova-Flo Vortex Flow Meters use a unique velocity sensor head to monitor volumetric flow rate. The built-in flow computer calculates mass flow rate based on a constant value of fluid density stored in the instrument’s memory. -
Page 10: Measurement Principle Of Vortex Flow Meters
Chapter 1 Introduction Series 220/221 Instruction Manual Vortex Shedding Frequency Von Karman vortices form downstream of a shedder bar into two distinct wakes. The vortices of one wake rotate clockwise while those of the other wake rotate counterclockwise. Vortices generate one at a time, al- ternating from the left side to the right side of the shedder bar. - Page 11 Series 220/221 Instruction Manual Chapter 1 Introduction Flow Velocity Range To ensure trouble-free operation, vortex flow meters must be correctly sized so that the flow velocity range through the meter lies within the measurable velocity range (with acceptable pressure drop) and the linear range.
-
Page 12: Reynolds Number Range For The Innova-Flo
Chapter 1 Introduction Series 220/221 Instruction Manual ™ As shown below, Innova-Flo Vortex Flow Meters exhibit a constant Strouhal number across a large range of Reynolds numbers, indicating a consistent linear output over a wide range of flows and fluid types. Be- low this linear range, the intelligent electronics in Innova-Flo automati- cally corrects for the variation in the Strouhal number. -
Page 13: Flow Meter Configurations
Series 220/221 Instruction Manual Chapter 1 Introduction Flow Meter Configurations Innova-Flo™ Vortex Flow Meters are available in two configurations: • Series 220 in-line flow meter (replaces a section of the pipeline) • Series 221 insertion flow meter (requires a “cold” tap or a “hot” tap into an existing pipeline) Both the in-line and insertion configurations are similar in that they both use identical electronics and have similar sensor heads. - Page 14 Chapter 1 Introduction Series 220/221 Instruction Manual The meter includes a local 2 x 16 character LCD display housed within the enclosure. Local operation and reconfiguration is accomplished using six push buttons. For hazardous locations, the six push buttons can be operated through the sealed enclosure using a hand-held magnet, thereby not compromising the integrity of the hazardous location certification.
