PCE-VS Rotameter

PCE-VS Rotameter
plastic rotameter for measuring flow in pipes and vents for air
Nm3/h or water l / h , depending on model

The rotameter is an instrument to determine the flow of fluids, e.g. liquids or gases in pipes. The rotameter of the VS series operates on the principle of the body in suspension. In the rotameter's conical plastic test tube there is a body in suspension that is lifted by the inertia of the fluid itself. How high the body in suspension reaches depends on the flow rotameter. If you increase the flow, the flow resistance increases. The suspension of the rotameter body rises and increases the body surface between the suspension and the glass tube. This decreases the flow resistance until it is identical with the sum of the strength of the suspended body weight and buoyancy. The level serves as a measure for the flow and can be read on a scale on the rotameter. Therefore, the rotameter is available in different versions. The rotameter is sent by default with a scale in l / h for water or Nm ³ / h for air. The reading of the flow is facilitated by two adjustable set-point indicators integrated into the rotameter.

Additional components
- Alarms contacts
The alarm contacts VSK2 and VSK1 serve as external control for the flow you want to limit. They are inserted into the guide and can be adjusted to any value of the marked scale. A magnet permanently attached to the floating body opens or closes a reed switch built into the alarm contact. The switching function is stable. This means that the switching state remains active even if the magnet is removed from the contact. When installed after an alarm contact, keep in mind that you must change the standard floating body with the floating body magnet.
