The Model KAL-A thermal flow sensor for water-based liquids features KOBOLD's revolutionary temperature-compensating electronics. The compact, one-piece thermal flow sensor with no moving parts provides reliable readings largely unaffected by temperature or physical characteristics of a wide variety of water-based process liquids. This breakthrough is made possible through the use of state-of-the-art microprocessor technology. The microprocessor can be field calibrated to the liquid properties and operating range in a simple, five-minute set-up procedure. This intelligence, coupled with a no-moving-parts design, make the KAL-A flow sensor a superior performer in many applications. To further enhance the versatility of the KAL-A series, it is offered in a 3-A compliant version. The thermal flow sensor applies the KAL's advanced microprocessor-based technology to the problem of flow rate detection. Although the calorimetricly sensed output is non-linear in nature, it is extremely repeatable. The KAL-A incorporates the same 8-segment LED display found in the flow switch, with an optional PNP setpoint alarm relay if desired.
