Calorimetric flow switches

Flow Switches – Liquids
We can provide a flow switch for most any application. Liquid flow switches with no moving parts for monitoring flow of water, oil, chemicals, and other media. From pipe sizes as small as 4 millimeters O.D. up to 24 inch O.D. and higher. With flow rates from 2 milliliters per minute, to 20,000 Gallons per minute.

Calorimetric flow switches (insertion type)

Calorimetric flow switches (inline type)

KAL-K Flow Switch

Trend and set-point display with 8 LED’s
Operating Temp up to 250F
PNP N.O. or N.C. output or optional Dry Contact output
24VDC or 120VAC power options
Explosion Proof and 3A Sanitary options

Inline Flow Switch with LED Display (Type 4320.1-, 4321.1-)

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

KAL-D Flow Switch

No Moving Parts
Switching Range 0.15 to 6.6 Ft/Sec.
Max. Pressure 580 PSIG
Max. Operating Temperature 210°F
Clean-In-Place to 250°F
¼ or ½ NPT or BSP connection

Inline Flow Switch with LED Display (Type 4320.xx-M)

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.

P-R-O 50

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" or "relative to" the full flow rate. No other flow sensor could do it this simply or effectively.

CoolGuard (Type 4000)

Compact electronic unit with no moving parts
No adjustment or calibration needed
Maintenance free
Fail Safe Normally Open switch
Economical Protection even for the most critical cooling systems
Designed with the OEM in mind

Insertion flow switch (Type 4114.73)

4114.73 flow captor is an AC switch with adjustable setpoint and Normall Open operation. Excellent for applications requiring AC power and where space is minimal. Adjustable from 2 to 200 cm/s trip point.

Flow Switch with Analog Display (Type 4120.1-, 4121.1-)

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. The unit can provide an adjustable setpoint based on % of full flow or can be set to an actual velocity via the indexed "range" potentiometer. It also gives a flashing LED indication of setpoint position as well as a Green LED indication of Flow OK.

Flow Switch with Analog Display (Type 4120.81 MS 141)

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 Relays.

Flow Switch with Analog Display (Type 4120-52-53M)

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.
