Connections
Flow block connection by flexible hoses 1 - 2 metres (3 - 6ft) long.
Adaptors
Adaptor Fitting kits and flanges are available to suit the range of flow blocks. Consult the sales office.
Flow
Measured by the electronic count of an axial turbine designed to minimise the effects of variation in
temperature and viscosity. The EU version displays flow in lpm, the US version displays flow in gpm.
Accuracy: ± 1% of full scale.
Pressure
Glycerine filled dual scale pressure gauge bar / psi connected by capillary tube to a shuttle valve
built into the flow block thereby always indicating the high pressure side of the valve regardless of
flow direction.
Accuracy: ± 1.6 % of full scale.
Temperature
Sensed by a thermistor pick-up in the oil flow for fast response. Temperature is permanently
displayed in °C/°F.
Accuracy: ± 1°C, 2°F.
Seals
Viton seals compatible with oil, water/oil emulsion are fitted as standard. EP seals for phosphate-
ester are available to special order.
