Details

The FD flow switch works using thermal dispersion technology where the temperature of a heated sensor is compared to the temperature of an unheated sensor. This temperature difference is greatest at no flow and decreases as flow rate increases. The unheated sensor acts as a reference such that the instrument only senses flow rate changes and is unaffected by process temperature changes.

FEATURES

  • Adapts to ⅛” Tubing thru ¾” Pipes
  • Low Flow Rate Detection
  • Explosion Proof Enclosures
  • 316L Stainless Steel, Optional Hastelloy C-276
  • No Moving Parts
  • Pressures to 10,000 PSIG

Details

The QX series flow switch offers the same reliability as our FX series and also offers a faster response time. These fast response flow switches are used when the response time in detecting the increase or decrease of flow is critical. With no moving parts exposed to the process they will provide extremely reliable and repeatable operation in virtually all liquids, gases, and slurries.
