Bamo IDP Plastic Flow Indicator use the principle of variable area flow-meter: the fluid flow raises a diver in a conical tube, expanding the cross section of the passage of fluid. The diver moves up proportionally to the flow-rate. Standard equipment includes a graduated scale in l/h of water at 20 °C.
In options there are specific scales; Air in Nm3/h (1 to 9 bar ABS); HCl at 30 / 33 %; NaOH at 30 % and at 50 %. See the data sheet 730-06 With magnetic diver versions, the Z60 transmission ruler converts the diver position into a 4-20 mA signal. See the data-sheet 730-07.
Bamo IDP Plastic Flow Indicator Features:
- Direct reading
- All wet parts in plastics
- Measuring tubes: PVC or Polysulfone
- Ranges: Up to 60 m³/h
- Specific scales for Air, HCl, NaOH, etc.
Flow indicators must be installed vertically with rising fluid. It is recommended to have a length upstream of 10 x ND and a length downstream of 5 x DN.
- Adjustable contacts
- 4-20 mA transmitter
