KSM Variable Area Flowmeter and Switch

Brand: KOBOLD Instruments, Inc.

The KOBOLD Plastic Flow Meters of Model KSM are based on the float principle with the float moving freely without the greatest diameter of the float.

The standard flow meters are supplied with a scale for water (+20 °C), a percentage scale, O-rings, two setpoint indicators and a guide rail for accessories. The measuring tube is available in polysulfone (KSM-2...) for less aggressive media or in Trogamide (model KSM-1...) for simple water or air applications.

The materials are resistant to impact, bending and compressive stresses. Optional threaded fittings can be fitted on the external threads integrally extruded at the ends. The floats are supplied with integrated magnets for operation with a bistable reed contact.
Features
  • Rugged and Corrosion Resistant
  • Special Scales can be Attached
  • Guide Rails for Limit Switches (can also be Retrofitted, only Replacement of the Float is necessary)
  • Nominal Sizes, Measuring Range and Measuring Tube Material are all Marked on the Measuring Tube
