The KOBOLD KSK plastic flowmeter/switch operates on the basis of the well known variable-area principle. The media flows upward through a conical measuring tube. The float is lifted by the flowing media and indicates the instantaneous flow rate on the scale attached to the flowmeter. The KSK series is all-plastic, with bodies made of polyamide or polysulfone 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 or air. Compressed air scales are available in SCFM, calibrated for direct readings at operating pressures from 0 to 145 PSIG. The compressed air scale table on page three of the datasheet shows the available ranges and calibration pressures for each meter size.
