PDP |
• 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.
PDP 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 proportionnaly 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 %. See data -sheet 731-04
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.
