Mounting Procedure
1.
Avoid places within the immediate proximity of equipment producing electrical interference
(such as
motors, transformers, radio transmitters, electrolytic cells, or other equipment
causing electromagnetic or electrostatic interference
).
2.
Avoid places where excessive pipe vibration occurs
.
3.
Avoid places where fluid runs in a pulsating form.
4.
Avoid places where there is
direct sunlight
. If this is unavoidable, use an appropriate
shade
5.
Avoid places where
corrosive atmospheres
or
high humidity conditions
obtain.
6.
Avoid places of
too great an elevation or constricted areas
where clearance for installation or
maintenance work is not provided.
7.
Design piping so that the detector pipe is always filled with fluid, whether the fluid is flowingor
not.
8.
The detector has no adjustable piping mechanism. Install an adjustable short pipe where needed.
9.
Chemical injections should be conducted on the downstream side of the flowmeter.
4.2.1 Pipe checks
(1)Before installing pipes, check for any leaning or misplacement (or eccentricity) as illustrated in Figure
4.1. An attempt to unreasonably connecting pipes that are inclined may lead to a detector breakdown or
fluid leakage. Connecting pipes in an eccentric state may also cause local wears and tears of linings and
grounding rings, as well as measurement errors.
Before installing pipes, make sure to flash the interior of the pipes to remove deposited matters.

(b) Pipe axis misplacement (or eccentricity)
