KSK - Plastic Flowmeter and Switch
The KSK plastic flowmeters/ flow switches operate on the basis of the well known variable area principle. The medium flows upward through a conically widening plastic measuring tube. The float is lifted by the flowing medium and indicates the instantaneous flow rate on the scale attached to the flowmeter. The KSK series is all plastic with bodies made of nylon Polysulfone or PVDF to handle aggressive media.
For the control of flow setpoints, a bistable switch can be provided for the instrument. Reed contacts or transistor switches are available and can be used to monitor and alarm on an upset flow condition. The transistor switch has an LED on the contact housing to indicate switching status.
Measuring scales are available for water and air. Compressed air scales are available in SCFM, calibrated for direct readings at operating pressures from zero to 145 PSIG. The compressed air scale table shows the available ranges and calibration pressures for each meter size.
