จุดเด่นของ Thermal Dispersion Flow Switch
- Flow switch employing thermal mass flow sensing technique for the detection liquid and gas flow
- No moving parts and no leak paths, no o-rings or graph oil seals to wear, fail, or leak
- Point level switch for liquid level detection
- Wide operating temperature range -100 – 850 °F (-70 – 458 °C)
- Flow Switch range of 0-5 feet/sec (0-1.5 mps) liquids and 0.2-500 feet/sec (0.07 – 150 mps) gases
- Level Switch switches on level change 0.03″ (0.076 cm)
- Fast flow switch response time of 0.5 to 10 seconds (media dependant)
- Level switch response time of 0.1 to 1 second of wetting (media dependent)
- CE, CENELEC and CSA approvals
- Insertion length from ½” to 39⅜” (1.27cm to 100 cm)
