The DK 32 flowmeter features horizontal connections and a standard metering valve in the foot or head of the device. The DK 34 flowmeter, on the other hand, features vertical process connections and no valve.


Differential pressure regulator

It is possible to directly connect a differential pressure regulator in order to ensure constant flow in the event of fluctuating operating pressure.
