  • 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 re- commends 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 6: Chapter 1 Introduction

    Chapter 1 Introduction Chapter 1 Introduction Innova-Flo™ Vortex Flow Meters The Sierra Instruments’ Series 240 In-Line and the Series 241 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 7: 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.

    How the Innova-Flo Vortex Flow Meter Operates Figure 1-1. Series 240 In-Line Vortex Flow Meter ™ Sierra Series 240 and 241 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 9 Chapter 1 Introduction Series 240/241 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 oth- er wake rotate counterclockwise. Vortices generate one at a time, alter- nating from the left side to the right side of the shedder bar.
  • Page 10 Series 240/241 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 11 Chapter 1 Introduction Series 240/241 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.
