All hydraulic connections should be made by suitably qualified personnel.
l
Avoid sharp bends because high pressure hoses will deflect and straighten under pressure.
l
A preliminary check of the hydraulic system's oil supply, pump rotation, filters, oil lines,
l
cylinder rods, as well as looking for external leaks, should be made prior to installing the unit.
Although the unit can be used in both flow directions, the preferred direction is indicated by
l
the larger arrow on the panel. When used for reverse flow tests, slightly lower accuracies
may be obtained depending on the oil viscosity, density and compressibility.
The unit should be connected to the hydraulic circuit by means of flexible hoses 3 - 6 ft.
l
(1 - 2 metres) long.
The use of quick-disconnect couplings can save time. Make sure the hoses are long enough
l
so the unit can be used safely on the machine.
The hoses and fittings at the inlet must be of adequate size for the flow being tested.
l
Elbows, rotary couplings etc., at the inlet and outlet ports should be avoided to ensure
accurate readings.
The use of the flexible hoses will help to isolate the unit from vibration which often exists.
l
The internal burst discs are to protect the unit, not the hydraulic installation. Always ensure
l
the appropriate relief devices are fitted to protect the installation.
All hydraulic connections should be made by suitably qualified personnel. Inlet and outlet connections
should always have a similar bore size to that of the flow meter to prevent venturi or constriction effects.
