SAGE METERING, INC.THERMAL MASS FLOW METERS

• FOR MEASURING GAS FLOW

2
HISTORY OF SAGE

• Founded in Sept 2002 by Managers from other
  Thermal Mass Flow Meter companies We are
  dedicated to extraordinary customer service
• Our Management and Staff have over 120 years
  experience in Thermal Mass Flow Meters, and we
  have brought to the market many important
  innovations from our high performance, award
  winning Flow Meters

THE TECHNOLOGY
4
WHAT IS A THERMAL MASS FLOW METER?

• It is a Meter that directly measures the Gas Mass
  Flow based on the principle of conductive and
  convective heat transfer more detail later

5
MEASURE MASS FLOW RATE OR TOTALIZE COMMON GASES

• Air (Compressed Air, Blower Air, Blast Furnace
  Air, Combustion Air, Plant Air, Make-Up Air)
• Natural Gas (Plant Usage, Sub-Metering, Burner
  Control, Combustion Control, etc.)
• Flare Gas (Vent Gas and Upset Dual Range)
• Nitrogen, Argon (Steel Production)
• Aeration Air, Digester Gas, Bio Gas, Landfill Gas
• Oxygen (for Combustion Control or Ozonators)
• Methane, Propane, Hydrogen, CO2, Helium
• Chlorine (Hastelloy Sensors Required)

6
WHAT DOES A THERMAL MASS FLOW METER CONSIST OF?

• All Sage Flow Meters have Probes (Insertion
  Style) or Flow bodies (In-Line Style) that
  support a pair of Sensors which are in contact
  with the gas

7
WHAT DO THE SENSORS CONSIST OF?

• The Sensors are RTDs, which are resistance
  temperature detectors
• They consist of highly stable reference-grade
  platinum windings
• In fact, we use the same material that is used as
  Platinum Resistance Standards at the National
  Institute of Standards (NIST)

8
ARE THE SENSORS RUGGED?

• The RTDs are clad in a protective 316 SS sheath
  for Industrial Environments

9
THE BASIC PRINCIPLE

• One of the RTDs is self-heated by the circuitry
  and serves as the Flow Sensor
• The other RTD acts as a Reference Sensor.
  Essentially it is used for Temperature
  Compensation

SAGE PROPRIETARY SENSOR DRIVE CIRCUITRY

• The Sage Proprietary Sensor Drive Circuitry
  maintains a constant overheat between the Flow
  Sensor and the Reference Sensor
• As Gas Flows by the Heated Sensor (Flow Sensor),
  the molecules of flowing gas carry heat away from
  this sensor, and the Sensor cools down as it
  loses energy
• .....Continued

11
SAGE PROPRIETARY SENSOR DRIVE CIRCUITRY -
continued

• The circuit equilibrium is disturbed, and
  momentarily the temperature difference between
  the Heated Sensor and the Reference Sensor has
  changed
• The circuit will automatically (within 1 second),
  replace this lost energy, by heating up the Flow
  Sensor so the overheat temperature is restored

12
HOW DO THE RTDs MEASURE MASS FLOW

• The current required to maintain this overheat
  represents the Mass Flow signal
• There is no need for external Temperature or
  Pressure devices
