Flowmeter Employs Hinged Flap

The KOBOLD TSK Series flap style flowmeter employs a hinged flap, a.k.a., vane, within the flow stream. As the flow rate changes, the flap rotates in its fitting. The flap is attached to a mechanical measuring indicator via a dampening mechanism and a process sealing system, providing visual measurement of system flow.


The indicating mechanism can be fitted with optional adjustable setpoint switches, a 4- to 20-mA transmitter with HART protocol or Profibus-PA. A wide variety of wetted materials are available including 316L stainless steel, Hastelloy C22, polypropylene, and PTFE, making this flap style flowmeter suitable for numerous applications in measuring aggressive liquids. The flap design leaves very little flow restriction; therefore, very little pressure drop exists across the flowmeter.
