Switching for Low Flows of Liquids and Gases
Optional Panel Mounting Kit
The KDG/KDF series micro-flowmeters operate on the variable-area float principle and are designed for the measurement of very low gas and liquid flows. Flow can be set exactly within the measuring range using the integral precision metering valve. All meter ranges can be optionally fitted with 1 or 2 adjustable inductive proximity switches which may be configured to identify certain flow conditions. Two switch types are available: 1.) Monostable: Switch activates momentarily as the stainless steel float passes by upon rising or falling flow or 2.) Bistable: Switch activates as the stainless steel float rises and remains active until the float falls past the switch on decreasing flow. All switches require the addition of a suitable external, NAMUR relay for operation. A panel mounting kit is also available as an option.
