    Chapter 1 Introduction Series 100 Instruction Manual LFE—Laminar Flow Element (LFE) or bypass generates pressure drop forcing a small fraction of the total flow to pass through the sensor capillary tube. THE SMART-TRAK FLOW SENSING PRINCIPLE The operating principle of the Smart-Trak instruments is based on heat transfer and the first law of thermodynamics.
  • Page 11 Series 100 Instruction Manual Chapter 1 Introduction Figure 1-2. Flow Measuring Principle Figure 1-3. Sensor Temperature Distribution Figures 1-2 and 1-3 show the mass flow through the sensor tube as inversely proportional to the temperature difference of the coils. The coils are legs of a bridge circuit with an output voltage in direct pro- portion to the difference in the coils’...

Linear Range of the Transducer’s Output Signal In the Smart-Trak mass flow controllers, the gas which flows through the monitoring section is precisely regulated by the built-in electromagnetic valve. The normally closed valve is similar to an on/off solenoid valve, except that the current to the valve coil, and hence the magnetic field, is modulated so that the ferromagnetic valve armature, or valve plug, assumes the exact height above the...
