GENERAL DESCRIPTION

The KAL electronic flow switch continuously monitors the flow of liquid media. It can be used wherever flows must be monitored with a minimal loss of pressure. The KAL’s one-piece, stainless steel sensor has no moving parts making the KAL very reliable. High strength is another advantage inherent in this design allowing use at high pressures, and virtually eliminating any chance of mechanical damage.

Operation

The KAL design is based on the timeproven calorimetric principle. The sensor is internally heated to a few degrees above the temperature of the medium. Flow of the medium causes removal of heat from the sensor, resulting in a cooling effect. The degree of cooling is a measure of the flow velocity.

The KAL electronic modules allow the user to interface with the sensor to provide access to flow or temperature control in his process. The system can act as either a flow switch only, or a combined flow and temperature switch. Switching is achieved by means of internal SPDT relays.

The microprocessor based design of the KAL distinguishes it from the competition. Full temperature compensation of the switch point is readily obtained through a simple, one-time, calibration procedure. This assures elimination of set-point drift caused by temperature variations in the process liquid.
