Description
Kobold KSM Variable Area Flowmeters and Switches Plastic are based on the float principle with the float moving freely without friction in the measuring tube. From nominal size DN65 the devices are provided with a guide rod to stabilize the floats. The indication point is at the greatest diameter of the float. The standard flowmeters 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 (KSM2…) 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.
Kobold KSM Special Advantages
- Rugged and corrosion resistant
- Special scales can be attached
- Guide rails for limit switches (can also be retrofitted, only replacement of thefloat is necessary).
- Nominal sizes, measuring range and measuring tube material are all marked on the measuring tube.
Applications
- Cooling circuits
- Water treatment
- Plant engineering
