KDK Variable Area Flowmeters From Kobold Instruments

Kobold Low Volume Flowmeter The Kobold KDK Variable Area Flowmeters functions at pressures up to 1850 PSIG. Its armored design includes an integral needle valve (also good to 1850 PSIG) for control of both liquid and gas flows. The 316 series stainless steel and PTFE/PFA gasket components are compatible with a large variety of process media.

Up to two switches are available to provide process control capability. The switches are proximity type and can be operated in an intrinsically safe mode with our model EX series control relays. The EX will provide SPDT dry-contact switching appropriate for all your controlling and signalling applications.
