Connect the RFIK into the hydraulic system as required using two 1 - 2 metre (3 - 6 ft) long hoses. Ensure
that the flow you wish to measure is passing through the RFIK in the direction of the double-arrows on the
flow indicator dial. Flow is allowed in the direction of the single arrow, but this flow will not be measured.
Measurement and Indication
Flow
Measured by a tapered metering piston moving
within a fixed, sharp edged orifice designed to
minimise the effects of changes in temperature and
viscosity. The piston movement is proportional to
the change in flow rate. In reverse the piston moves
back to allow the flow to return at low pressure.
Accuracy: ± 4% of full flow over range 20 - 40 cSt.
Pressure Drop
At full flow with oil viscosity 28 centistokes.
Model Pressure Drop at Max. Flow
RFIK30 4.1 bar (60 psi)
RFIK60 5.2 bar (76 psi)
RFIK120 6.5 bar (94 psi)
RFIK200 15 bar (218 psi)
Pressure
Glycerine filled 63 mm (2 1/2") pressure gauge
0 - 420 bar (0 - 6000 psi) gives a continuous reading
of system pressure.
Accuracy: ± 1.6% of full scale

Temperature
For continuous use at fluid temperatures up to
80°C (180°F), for intermittent use for less than 10
minutes, at up to 110°C (230°F). Indicated in °C
and °F by a thermometer built into the flowblock to
measure temperature changes in the fluid passage.
Accuracy: ± 2.5°C (± 5°F)
Calibration
The RFIK 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.
