1. 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

3. 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. Click Here to Skip Theory
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

10. 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
