Installation
All flowmeters are inspected and calibrated prior to shipment, and are sent out in perfect
condition. Should damage be present on receipt of the product please inspect the delivery
packaging for visible mishandling and contact the parcel service / freight forwarder.
Maintain any protective plugs/caps until installation.
2.1
Mechanical Installation
Before installing your flowmeter, it is recommended that you confirm the meter is
suitable for your application conditions such as; fluid compatibility with meter materials,
flow rate, pressure, and temperature. Fluid entering the meter must remain a liquid at all
times; avoid solidification or gelling of the metered medium. If hydraulic shock or pressure
surges of any kind are possible, the system upstream of the meter must be fitted with a
surge suppressor or pressure relief valve to protect the meter from damage.
2.1.1
Installation Orientation
The flowmeter MUST be mounted with the rotor shafts in a horizontal plane. Failure to
mount your Oval Gear flowmeter in the correct orientation
(as shown in the diagrams
below)
will cause the weight of the rotors to bear down on the thrust bearings. The short
term effects of incorrect mounting orientation will be a loss in accuracy, with long term
effects ranging from reduced lifespan to fairly rapid catastrophic damage.
Liquid can flow in a horizontal direction, or a vertical direction, but in each case the rotor
shafts must be in a horizontal plane. This is achieved by mounting the meter so that the
terminal cover, or integral instrument display, is facing in a horizontal direction. For pulse
output flowmeters the direction of flow is not important, as the output is non-directional.
Please note that all flow-meters are calibrated with either
Castrol ISO4113
or
Exxsol D130
immediately prior to shipment, residual oil may be present;
please take the appropriate precautions for health and safety. An MSDS is
available from the manufacturer or via an internet search.
