The Kobold KAL-L thermal air flow switch allows rapid detection of flow rate change of non-hazardous gases. Fast reaction times are guaranteed by the Kobold KAL-L thermal air flow switch's analog electronic design. Through use of two RTDs, one to sense flow and the other to detect ambient temperature, the switch can compensate for thermal changes in its surroundings. This "smart" behavior minimizes erroneous switching due to spurious changes caused by things such as the weather. With no moving parts, the Kobold KAL-L thermal air flow switch provides dependable service with negligible pressure loss.
Any conceivable pipe size can be accommodated by the Kobold KAL-L thermal air flow switch's insertion style design. Installation is simple. Knowledge of the flow velocity in your system is all that you need to make the Kobold KAL-L thermal air flow switch work.
