ASSOCIATED EQUIPMENT
Filters
In order to guard against seizure of the meter working parts, due to
the ingress of oversized particles too large to be swept through the
meter, it is recommended that filter be fitted up-stream of the meter
to filter out particles in excess of 0,1 mm in diameter. For further
infomation do not exitate to contact our Technical Department in
CRAIND IMPIANTI
Valves
Remotely controlled valves, when fitted, should be of the fast
closing type to minimized the effect of over-run at the end of a
batch delivery. Generally, pneumatically operated valves are
recomended. Our Technical Department in CRAIND IMPIANTI
will be pleased to offer a suitably spiced valve to suit your
requirements.
Pumps
Use pumps free from pulsation (centrifugal or volumetric types).
Positive displace rent pumps inherently produce pulsations which
can cause measurement errors.
Air Separation
If there is danger of entrained air being present in the liquid then a
suitable de-aeration device must be installed upstream of the meter
otherwise air will be measured as liquid.
