Maintenance and service
For calibration please return the flow indicator to Webtec or your local distributor.
Calibration
The FI750 is calibrated at a mean viscosity of 28 cSt using ISO32 hydraulic mineral oil to ISO11158 category HM.
Recommended period between calibrations is 12 months. Maximum period between calibrations is 36 months. Unit accuracy may be affected by
operating cycle, fluid condition or extended periods between recalibrations.
Accessories
Optional 63 mm (2.5”) diameter glycerine filled pressure gauge fitted directly into a connection in the block or remotely connected by micro bore hose
and test point. External load valve to enable a system to be tested under load.
For accessories specifications please consult Webtec or your local distributor.
