Thermal mass flow meter

Thermal mass flow meter accurately measures gas mass flow, serving a wide range of industries and applications.

Molasses flow meters are designed to monitor the flow of high-viscosity liquids like molasses, ensuring reliable measurement. For the best deals on thermal mass flow meters, reach out to VSAN Sensors, a top sensor manufacturer in Chennai.

Principle of Operation:

Flow Body or Probe Types: The meter supports two sensors in either in-line flow bodies or insertion-style probes.

Sensor Types: The sensors are resistance temperature detectors (RTDs), made of durable platinum windings encased in a protective 316 SS or Hastelloy C sheath.

Function of Sensors: One sensor is heated by an integrated circuit and functions as the flow sensor, while the second acts as a reference sensor to measure gas temperature.

Proprietary Circuitry: The Sage proprietary circuitry maintains continuous overheat between the flow and reference sensors.Heat Transfer Process: As gas flows past the heated sensor, gas molecules transport heat away, causing the sensor to cool, thus losing energy.

Circuit Balance Disruption: The loss of heat disrupts the circuit balance, altering the temperature difference (ΔT) between the

heated RTD and the reference sensor.

Energy Restoration: Within a second, the circuit restores the lost energy by heating the flow sensor, adjusting the overheating temperature.

Mass Flow Signal: The electrical power needed to maintain this overheating directly correlates to the mass flow signal.
