Calorimetric

 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 KAL-K thermal flow switch utilizes advanced microprocessor based technology to provide a stable setpoint regardless of changes in temperature. The KAL-K’s solid-state switches can be configured as NPN or PNP and normally-open or normally closed.

 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 4120 flow-captor is simple to install via the 1/2 NPT threaded probe tip (also available in BSP). It provides both Absolute and Relative flow monitoring. 

 4320.xx-M units are ruggedized, sealed versions of the in line flow-captor model 4320 above. The M units are housed in a stainless steel housing with screw on, gasketed front cover - excellent for harsh environments or outdoor use.

 CooLGUARD is especially designed, for all types of cooling systems, as a reliable alternative to failure prone mechanical flow switches.

 The new captor P-R-O 50 is for applications requiring RELATIVE measurement and set-point of flow rate. This means that the actual velocity of the flow or the quantitative measurement in GPM is not known and is not important. What is important is that the set-point can be set as a "percentage of"…

 The 4320.1- is a precise, metering flow switch with adjustable range and set-point for industrial applications. You may set an exact flow set-point and simultaneously measure flow speed.

 4120.81 MS 141 is a ruggedized, sealed version of the insertion flow-captor model 4120 above. This unit is housed in a stainless steel housing with screw on, gasketed front cover - excellent for harsh environments or outdoor use. They are powered with 120VAC and contain SPDT electromechanical…

 4120-52-53M is a ruggedized version of the 4120 DC powered unit and also comes in a stainless steel housing with screw on, gasketed cover. It can be provided with an AC Thyristor output in Normally Open or Normally Closed configuration.
