In-Line Vortex Multi-Parameter Mass Flow Meter Sierra Series 240 and 241 Innova-Mass™ Multi-Parameter Vortex Mass Flow Meters use a unique sensor head to monitor mass flow rate by di- rectly measuring three variables–fluid velocity, temperature and pres- sure. The built-in flow computer calculates the mass flow rate and volu- metric flow rate based on these three dire

Chapter 1 Introduction Series 24-HP Instruction Manual Vortex Shedding Frequency Von Karman vortices form downstream of a shedder bar into two dis- tinct wakes. The vortices of one wake rotate clockwise while those of the other wake rotate counterclockwise. Vortices generate one at a time, alternating from the left side to the right side of the shedder bar. Vortices interact with their surrounding space by over-powering every other nearby swirl on the verge of development. Close to the

Series 24-HP 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. The measurable range is defined by the minimum and maximum velocity using the following table. Gas Liquid 25 ft/s 3 ρ Vmin 1 ft/s English ρ (lb/ft ) Vmax 300 ft/s 30 ft/s 37 m/

Chapter 1 Introduction Series 24-HP Instruction Manual As shown in Figure 1-3, Innova-Mass™ meters exhibit a constant Strou- hal number across a large range of Reynolds numbers, indicating a con- sistent linear output over a wide range of flows and fluid types. Below this linear range, the intelligent electronics in Innova-Mass automatically corrects for the variation in the Strouhal number with the Reynolds num- ber. The meter’s smart electronics corrects for this non-linearity via its sim

Series 24-HP Instruction Manual Chapter 1 Introduction Pressure Measurement Innova-Mass Flow Meters incorporate a solid-state pressure transducer isolated by a 316 stainless steel diaphragm. The transducer itself is mi- cro-machined silicon, fabricated using integrated circuit processing tech- nology. A nine-point pressure/temperature calibration is performed on every sensor. Digital compensation allows these transducers to operate within a 0.3% of full scale accuracy band within the entir
