    How the Innova-Mass Vortex Mass Flow Meter Operates Figure 1-1. 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 pressure.

  • Page 10: Vortex Shedding Frequency

    Chapter 1 Introduction 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 11: Flow Velocity Range

    Series 24-HP Instruction Manual 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: Temperature Measurement

    Chapter 1 Introduction As shown in Figure 1-3, Innova-Mass™ 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-Mass automat- ically corrects for the variation in the Strouhal number with the Reynolds number.

  • Page 13: Pressure Measurement

    Series 24-HP Instruction Manual 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.

The value returned indicates the state of the alarm, and will be 1 only if the alarm is enabled and active. A zero value is transmitted for alarms that are either disabled or inactive, Registers 10001...
