| A Flow switch is normally a simple device that
monitors flow and sends a trip signal to another
device such as a pump to protect it. Some flow
switch applications are 1. Pump Protection 2.
Cooling circuit protection 3. High and low flow
rate alarm and general flow monitoring. Flow
switch types are used on air, steam and liquid |

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 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.

General Description
The vent-captor type 3202.- is a solid-state flow-monitor for air or gaseous media in a wide variety of industrial applications. Being totally encapsulated in epoxy resin with no moving parts, this small, compact unit operates with high precision and high repeatability in harsh industrial environments. The construction and design of the vent-captor ensures a long, maintenance-free life
Typical Application Examples:
vent-captor air flow-monitors are used to monitor air flow in a wide variety of industrial applications for air or gasous medium e. g. air conditioning, ventilation, air filter monitoring, extraction fans, blowers, damper regulators and controlling air flow rates in energy conservation systems. The vent-captor is also ideal for monitoring air flow in thyristor cabinets, motor/generators and shipping containers. |
