Specification
Ambient Operating temperature
- 5 to 40 °C (41 to 104 °F)
EMC Environment:
This equipment is intended for use within industrial and residential environments and does not suffer
any degradation in operation when subjected to test conditions according to requisite standards.
Connections
Flow meter connection by flexible hoses or steel pipes 200 mm minimum length (8 inches).
Adaptors
Adaptor Fitting kits and flanges are available to suit the range of flow meters. Consult the sales
office.
Flow
Measurement by the electronic count of an axial turbine or precision gears designed to minimise the
effects of variation in temperature and viscosity. The large digital display reads in lpm, IMP gpm or
US gpm, selected by push button and indicated by a cursor arrow on the display.
Accuracy: See flow block specification
Pressure
Glycerine filled dual scale pressure gauge
0 - 420 bar (0 - 6000 psi), 0 - 480 bar (0 - 7000 psi)
Accuracy: ± 1.6% of full scale.
Temperature
Sensed by a thermistor pickup in the oil flow for fast response. Temperature is permanently
displayed in °C or °F for either of the flow meters.
Accuracy: ± 1 °C (2 °F)
Speed
Rotational speed of motors, shafts etc, can be measured by optional infra-red phototachometer
and the readout can be programmed for one or more reflective marks.
Range 300 - 6000 rpm.
Accuracy: ± 1/4% of full scale with one count per revolution.
