URK – Glass Cone Variable Area Flow Meter With Flange Mounting

Brand: KOBOLD Instruments, Inc

The operation of the Kobold URK model flow meter/monitor is based on the suspended float principle.

It is used for measuring the flow rates in closed pipeline systems. The media flows upward through a glass measuring cone that becomes progressively wider at the top.

When media flow is present, the float rises and clearly indicates the respective flow rate on the scale provided on the measuring cone.

To monitor flow rate limits, the metal URK rotameters may be optionally fitted with “open collector” type proximity switches. By its special design, this model is particularly suitable for applications with low operating pressures.

Another advantage is offered by the very large sight glass, which optically allows direct flow observation.
