2. Installation
•
The Atrato must be installed in a positive pressure system. Ensure that
there is sufficient back pressure on the flowmeter to keep any gas in
solution.
Back Pressure >500mbar plus two times the liquid vapour pressure
backpressure
•
Locate the flowmeter in a sheltered position away from falling water.
•
Care must be taken to ensure that the end fittings on the meter are not
stressed during use. Ideally, flexible tubes should be used.
•
Ideally the meter should be installed with straight lengths of tube either
side for a distance of 10 pipe diameters upstream and 5 downstream.
•
Install the device well away from valves, regulators, bends and other
components that could cause excessive turbulence on the fluid
entering or leaving the meter.
•
If necessary, use spacer blocks and mounting clips to raise the pipe
work centre line 58mm above the surface.
•
It is good practice to use upstream and downstream isolating full bore
ball valves to facilitate easy meter installation or removal.
•
If push-
in 3/8” John Guest fittings are used, clip the pipes to the
mounting surface 300mm upstream and 150 downstream.
•
If there is any chance of air passing through the system, mount the
Atrato in a vertical pipe with the flow in an upward direction. Otherwise,
air can remain trapped in the meter and affect its performance.
•
The Atrato is not recommended for pulsating flow. Any pulsations must
be damped to less than 10Hz to prevent aliasing of measurement.
