Installation
Sensor Installation Guidelines
NO YES
For vertical installations
with descending flow
direction contact the
manufacturer.
Avoid operation of the
system with the pipe
partially empty.
Avoid installation of this
instrument near bends
in the piping or accesso-
ries such as valves.
If the system is under
pressure, opening the
ball valve before tight-
ening the fixing nut
could result in the
sensor being propelled
from the pipe line.
Never open the ball
valve unless the fixing
nut is properly tight-
ened.
For vertical installations,
use ascending flow
conditions only.
During normal operation
of the instrument, the
pipe must be completely
full of liquid, or com-
pletely empty.
Install the sensor away
from bends in the pipe
and accessories such
as valves.
Lock the center bushing
before opening the ball
valve.
Grounding Instructions
For correct operation of the meter, it is essential that the
sensor and the liquid be at the same electrical potential.
Always connect the sensor and the converter to ground.
For grounding with a cathode protection pipe, contact
the manufacturer.
