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. The large digital display reads in lpm, UK gpm
or US gpm, selected by push button and indicated by a cursor arrow on the display.
Accuracy: ± 1% of indicated reading (over 15 - 100% of range).
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 displayed in °C or °F
for either the internal or external flow block.
Accuracy: ± 1°C, 2°F.
Speed
Rotational speed of motor shafts etc., can be measured by optional infra-red phototachometer using
one or more reflective marks. Range 300 - 6000 rpm.
Accuracy: ± 1/4% of full scale with one count per revolution.
Seals
Viton seals compatible with oil, water/oil emulsion are fitted as standard. EP seals for phosphate-
ester are available to special order.
