NOTE
The layout of piping must ensure that the flow meter is filled with liquid at all
times and that no inclusions of air, foam or gas may occur.
Aquametro Oil & Marine recommends to install bypass valves.
The quantities from all consumers must be registered by the flow meter.
Correct layout of flow meter and accessories
If the flow meter is used for viscosities higher than 5 mPas, or if it is mounted on the suction side
of a pump, the pressure loss and the flow rate that can still be attained should be determined
with the help of the pressure loss curves provided in CONTOIL
®
Technical Information.
In addition, the pressure loss due to installed filters must be taken into consideration.
Select the flow meter and ancillaries according to the working conditions listed below:
Flow meters must be selected according to the maximum flow rate and not according to the
pipe diameter. If necessary, adjust the pipeline.
Flow rate (maximum expected application flow rate = maximum-continuous flow rate of flow
meter Qcont)

Non-Return-Valves
In order to avoid backflow and draining, Non-Return-Valves must be mounted after the flow
meter. Backflow and draining can cause faulty measurements and may damage the flow meter.
Pressure shocks during operation with the flow meter must be avoided
