RAGK Mini Rotameter Flow Meter
Brand: Yokogawa Electric CorporationThe RAGK Short Rotameter measures liquids and gases, designed with a conical glass metering tube that has a free rotating float.
The flow is indicated by the top of the float and can be read from the standard scale on the metering tube or from a connected scale.
Measurable Flow Rate:
- Water = 0.002 l/h to 600 l/h
- Air = 0.2 l/h to 6300 l/h
Meets High Safety Standards
The RAGK’s tube is fixed between two square formed heads and sealed with o-ring gaskets made of Buna or Viton, providing a higher level of safety. Its stainless steel rear wall stabilizes the construction, and a plastic cover protects the rotameter.
Features- Two different tube lengths
- Needle valves direct assembled in the head of the inlet or the outlet
- Inductive ring sensors (GR) as limit switches available
- Magnetic contacts (Reed sensors) for M3-tubes
- Inlet and outlet flow controller available
