Small Plastic Flow Indicator PDP

PDP flow indicator applies the principle of variable area flow-meter: the flow raises a diver in a conical tube expanding the cross section of fluid passage. The diver moves up proportionally to the flow-rate (diver is commonly named ''float''). Standard equipment includes a graduated scale in l/h of water at 20 °C. In options there are specific scales: Air in Nm³/h; HCl at 30...33 %; NaOH at 30 % & 50 %.

Precautions for mounting:

Flow indicators must be installed vertically with rising fluid. It is recommended to have a length upstream of 10 x ND and downstream of 5 x ND.


  • Direct reading
  • All wet parts in plastics
  • Materials: PVC, PSU, PVDF, EPDM
  • Scales from 2.5 up to 1,000 l/h of water
  • Other scales: Air in Nm³/h, HCl and NaOH.
  • Option: Adjustable contacts


PDP series are ideally suited for continuous measurement of flow for air and neutral, basic or acidic liquids.
