The KOBOLD TSK flap style flow meter employs a hinged flap (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 4-20 mA transmitter with HART® protocol or Profibus-PA®. A wide variety of wetted materials are available, including 316L stainless steel, Hastelloy® C22, and PTFE, making this flap style flow meter suitable for numerous applications in measuring aggressive liquids. The flap design leaves very little flow restriction; therefore, very little pressure drop exists across the flow meter. The flap design is also very tolerant of dirty liquids and liquids containing large solids.
