Thermal Dispersion Technology

ApplicationsThermal Dispersion

Magnetrol's Thermal Dispersion Mass Flow Meter provides mass measurement for air and gas flow applications. Electronics are contacted in a compact, explosion-proof enclosure and are powerful and simple to use. The THERMATEL Model TA2 mass flow transmitter measures flow by detecting heat dissipation from a heated surface. The sensor contains two mass balanced elements with precision matched RTDs. The reference sensor measures the process temperature; the second RTD measures the temperature of the heated sensor. The power to the heater is varied to maintain a constant temperature difference above the reference temperature. Applications include: combustion air, compressed air, natural gas, aeration air, digester/biogas, vent lines/flare headers, hydrogen lines.


  • Direct mass flow measurement of air and gas
  • Excellent low flow sensitivity
  • Process temperatures up to 400F
  • Rotate-able housing
  • FM/FMc/ATEX approvals
  • Resettable and non-resettable totalizers
