| In-line thermal dispersion flow meters Thermal Instrument Company |
Two sensors are exposed to the heat transferring effect of the flowing media. When the media composition is known, the mass flow can be calculated using the meter reading and the pipe cross sectional area. One of the flow meter sensors is heated, the other is allowed to follow the media temperature as a reference. The heat dispersion from the heated sensor is measured and used to calculate mass flow.
Some positive attributes of thermal dispersion flow meters:
- In-line and insertion configurations available to accommodate very small to large pipe sizes
- Rugged Construction – Stainless Steel with available protective coatings and other specialty metals
- No moving parts
- Measure liquid or gas in general, sanitary, and ultra pure applications
- Measurement not adversely impacted by changes in pressure or temperature
- Wide range of process connections
- In-line versions provide unobstructed flow path
- Wide turndown suitable for extended flow range
- Back up sensors for extended life
- Sensors do not contact process media
- Flow and total flow measured
- 4-20 mA output interfaces easily with other instruments and equipment
