KAL-A Calorimetric Meter/Switch

Brand: KOBOLD Instruments, Inc

The KOBOLD KAL-A uses the calorimetric principle to continuously monitor the flow of low viscosity water-based media. Flow rate is transmitted via a 4-20 mA output while an optional PNP switch provides an alarm function.

The transmission capability of the KAL-A is made possible by the high degree of temperature stability provided by its “intelligent” microprocessor based design. This digital approach also enables the use of a single RTD element to both heat the probe tip and measure it’s temperature. 

Integrating the heating measuring functions allows the probe to be machined into a single, continuous, protrusion-free surface. The absence of protrusions prevents contaminant from building up on the probe tip.

These design enhancements improve the KAL’s performance in two ways:
  1. The KAL's sensing stability is increased because contaminants cannot thermally isolate the prove from the liquid.
  2. System down-time associated with probe cleaning is dramatically decreased.
