The KAL-K thermal flow switch and KAL-A thermal flow sensor employ temperature-compensating electronics to provide reliable readings that are unaffected by temperature or physical characteristics of a wide variety of process liquids. This ability is made possible through the use of state-of-the-art microprocessor technology. The microprocessor can be field calibrated to the users’ liquid properties and operating range in a five-minute setup procedure. This intelligence, coupled with a “no moving parts” design, make the KAL suitable for use in virtually all applications. Both the KAL-K and KAL-A are available in a 3A-compliant version. The KAL-K incorporates an eight-segment bar-graph LED flow trend indicator and one flow alarm setpoint. The setpoint is fully configurable as NPN, PNP, normally open, or normally-closed. The KAL-A integrates microprocessor-based technology to solve the problem of rate detection. It incorporates a 4 mA to 20 mA, flow rate proportional output, the same eight-segment LED display found in the KAL-K, and an optional PNP set-point alarm relay.
