Flowmeters Type R


The flowmeters of the "R" series are designed for medium flow rates, made of Plexiglas with a calibrated conical bore formed directly in the structure. Axial or square, flanged or threaded connections are available on request. The accuracy of the instrument is: ± 5% fs. The maximum pressure of use is 10 bar. On request they can be made for PN 16, PN 25, PN 40.



  1. Application: Medium flowrate
  2. Fluids: Liquid and gases
  3. Accuracy: ± 5% of f.s.
  4. Max working pressure: 10 bar
  5. Max working temperature: 70 ° C
  6. PVC, AISI 304 or AISI 316 fittings


  • The models and flow rates in the flowmeters in the catalog always refer to use with water and air. With the use of air or gas in general, the flow rates are always referred to use at a temperature of 20 ° C and at atmospheric pressure. When the flow meters are installed inside a closed circuit, the pressures inside the instrument can be different from the atmospheric pressure. In this case, being compressible gases, the instruments must be calibrated and sized according to the process data. This is because otherwise the reading will be distorted.


This extremely simple type of tools does not require special measures. The assembly of the flowmeters have precise directions. In a vertical position with flow from bottom to top. In the flow meters equipped with a regulation tap, in addition to the instantaneous flow rate reading, it is possible to adjust the output flow.
