Features
  • Optimal Temperature Compensation
  • Simultaneous Monitoring of Temperature and Flow
  • Remote Probe Allows Installation with Minimal Clearance
  • Independent of Liquid Density
  • Can be Used with Extremely Low Velocities
  • No Moving Parts
  • Extremely Low Pressure Loss
  • Easy to Operate
  • Insensitive to Dirt

The KAL electronic flow switch continu- ously monitors the flow of liquid media. It can be used wherever flows must be monitored with a minimal loss of pres- sure. The KALs 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 time- proven 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.

Temperature Compensation

The KOBOLD KAL flow switch uses a microprocessor to compensate for temperature changes through use of an internal look-up table. End-users can easily adapt the equipment to the requirements of their unique installations. Compared to conventional calorimetric flow switches, the technically advanced design of the KAL provides a switch point which changes negligibly with temperature.

Selecting a System

The electronic flow switch consists of:

  • the controller
  • the sensor
The connecting cable between the two parts may be up to 330 feet long. (with KAL-E300 series units, temperature correction is required with cable lengths above 33 feet.)

Controllers

Three units are available. Each is com- patible with the full series of sensors. Electronic circuitry is located in a standard DIN housing (NEMA 1) for quick installation on terminal rails.



KAL-E100 Series

The KAL-E100 is equipped with a flow rate sensitive, isolated SPDT relay. The relay status is indicated by means of a green LED.

KAL-E200 Series

Same as the KAL-E100, but with a trend indicator for flow rate and switch point.

KAL-E300 Series

Same as KAL-E200 but with a temperature switch. In addition to monitoring the flow, this model can be used to monitor the temperature. The specified alarm temperature can be from 0176 F.

SPDT relays are activated if the flow drops below the specified flow velocity, or if the temperature drops below the specified temperature.

Sensors

All of the sensor models can be used with any of the three controllers.

Selection is a function of:

  • connector threads
  • max. operating pressure 1450 PSIG
  • max. medium temperature 176F (250 ̊F Optional)
  • sensor wetted parts
