KDG/KDF Miniature Variable Area Flowmeters From Kobold Instruments

Kobold Miniature Flowmeter The KDG/KDF Miniature Variable Area Flowmeters operates on the float principle and is designed to measure and meter low gas and fluid quantities. The flow may be set exactly within the measuring range using the integral precision metering valve.

The KDG/KDF Miniature Variable Area Flowmeters can be fitted with inlet or outlet regulators to maintain a constant flow rate.

Additionally, up to 2 bistable or monostable setpoint proximity switches may be mounted to identify certain flow conditions. Switches require an EX-3001 power supply/relay for each switch. See the flow accessories section for details on the EX-3001 relay.

A panel mounting kit is available as an option.
