Connections
By flexible hoses 1 - 2 meter minimum length (3 - 6 foot). Care should be taken to avoid constrictions
at the inlet or outlet port.
Adaptors
Adaptor Fitting 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 large analogue readout meter has high / low scales selected by a switch.
Accuracy: ± 1% of full scale.
Pressure
Glycerine filled dual scale pressure gauge 420 bar / 6000 psi (7000 psi / 480 bar for HT602/802)
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 displayed in °C/°F.
Accuracy: ± 2°C, 4°F.
Speed
Rotational speed of motors, shafts etc., can be measured by optional infra-red phototachometer
using one or more retro-reflective marks. Range: See Table.
Accuracy: ± 2% of full scale.
Seals
Viton seals compatible with oil, water/oil emulsion are fitted as standard. EP seals for phosphate-
ester are available to special order.
