Overview

Sierra was the first to introduce multivariable mass vortex flow meters to the market in the late 1990s with the InnovaMass "S-Series" product line-the 240S and 241S. The InnovaMass 241S inline version is a true workhorse in applications ranging from large pipes and ducts, to high pressure and saturated or superheated steam. The InnovaMass 241S is manufactured as a volumetric only version or a multivariable version.

Mass or volumetric flow monitoring of gases, liquids or steam
Ideal for pipes and ducts up to 72 inches (2M).
Measures five process variables with one process connection
- Mass flow rate
- Volumetric flow rate
- Temperature
- Pressure
- Fluid density
Low-cost alternative to Coriolis meters for large pipes and ducts
Easy single-point installation; hot tap and hot tap retractor available
Sensors located behind bluff body are well protected from pressure shocks and water hammer
Large LCD display and pushbutton interface; remote enclosure mounting available
Display of simultaneous total flow rates and process diagnosis

Loop-powered design simplifies wiring and signal processing
Mass flow equations - real gas, ideal gas, and AGA-8 algorithms for natural gas
Optional BTU measurement for steam and water
Fully field configurable
Rangeable down to Reynold's number of 5000
Precision platinum RTD
Complex density calculations performed without need for separate flow computer
Field validation/configuration to assure operating performance
Flow totalizer and alarms
Energy (BTU) Monitoring for real-time monitoring of energy consumption; compute and output energy use
