The KDG/KDF micro flowmeters operate on the float principle and are designed to measure low gas and liquid flows. Flow can be set exactly within the measuring range using the integral precision metering valve. The contrasting color background of the scale permits accurate data readings. Additionally, 1 or 2 adjustable switches may be mounted to identify certain flow conditions. A panel mounting kit is available as an option. Options 1. Limit Switches All meter ranges which have a stainless steel float can be fitted with optional, adjustable switches. Two types are available: Monostable: Switch activates momentarily as the stainless steel float passes by on rising flow. Bistable: Switch stays activated until the float falls past the switch on decreasing flow.
