Gas Flow Meters

Gas flow meters are devices used for measuring the flow rate of gases. They utilize different principles for measurement, including differential pressure, velocity, positive displacement, thermal sensing, and Coriolis effects. Differential pressure meters gauge the pressure decrease across a constriction, velocity meters gauge gas speed, positive displacement meters measure the flow rate by trapping and then releasing discrete volumes of gas, thermal meters detect heat transfer, and Coriolis meters measure the twisting of vibrating tubes. Each type has its advantages and limitations, with selection dependent on factors such as gas type, flow rate range, pressure, temperature, and required accuracy, for specific application needs. For further assistance and expert advice on selecting the right gas flow meter, the product experts at Centro will be glad to assist.

Kobold KSK - Polyamide Material Plastic Flowmeter and Switch
MPN:KOBOLD-00-KSK-PA
The KOBOLD KSK plastic flowmeter and switch delivers reliable flow measurement for liquids and gases in a corrosion-resistant package featuring polyamide or polysulfone construction that stands up to aggressive acids and alkaline solutions typically unsuitable for metal units. Operating on the variable-area principle with a PVDF float traveling within a clear conical measuring tube, this versatile instrument provides ±4% full scale accuracy across a wide measurement range from 0.006 GPM to 4.4 GPM for liquids or from 0.06 SCFM to 62 SCFM for air (with polysulfone models offering specialized calibration scales for pressures from 0 to 145 PSIG). The compact design can be equipped with either bistable reed contacts (N/O or N/C) or NPN transistor switches featuring LED status indication, providing reliable flow monitoring and alarm capabilities for critical process protection applications. With a maximum pressure rating of 145 PSIG and temperature capabilities up to 212°F (for polysulfone versions with brass or stainless steel fittings), these shock-proof instruments offer exceptional chemical compatibility while maintaining visual indication through their clear measuring tubes. Versatile connection options including PVC glue socket/NPT female fittings or brass/stainless steel NPT adapters in various sizes make the KSK series adaptable to numerous industrial applications requiring chemical resistance combined with accurate flow measurement and control.
