Flowmeters Type PL


The “PL”series flowmeters are produced entirely in Plexiglas with a calibrated and polished conical measuring hole obtained directly in the structure. They are provided, on request, with axial or angle, flanged or threaded connections. The precision of the instrument is: ±5% fs. Maximum working pressure is 10 bars. They can be produced, on request, for PN16, PN25, PN40.



  1. Applications: Medium Flowrate
  2. Fluids: clean liquids or gases
  3. Precision: ±5% fs.
  4. Maximum working pressure: 10 bar
  5. Maximum working temperature: 70°C
  6. Connections and Flow regulator: Brass, AISI 304, AISI 316
  7. Connections: Threaded, Flanged, Square, Inline


  • 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.
