The KAL-D series combines the features
of our legendary KAL-K thermal flow
switch with a compact size. The KAL-D
uses the calorimetric principle to monitor
the flowrate of non-viscous water-based
liquids. The sensor tip is heated to a few
degrees above the liquid temperature. As
the liquid flows across the tip, it is cooled
by the liquid.
The amount of cooling is
proportional to liquid velocity. The liquid
velocity is compared to the setpoint which
is field-adjustable by the user. A transistor
switch is activated when the flow setpoint
is reached. The KAL-D series has a
smooth measuring probe with no moving
parts making it exceptionally reliable and
insensitive to dirt and solids. The insertion
type probe allows for flow monitoring with
minimal system pressure loss.
Microprocessor-Based Temperature
Compensation
The KAL-D series achieves superior
compensation for changes in liquid
temperature during the measuring cycle
by use of a microcontroller. This method
of temperature compensation allows for
very precise correction of flow
measurement when liquid temperature
changes occur. |
