INSTALLATION
The sensor may be installed
in either a tank or pipe using
a customer-supplied Triclamp and tee assembly.
The sensor requires a 2-inch
Tri-clamp, a 2-inch type 1
gasket, and a 2-inch tank
ferrule or tee.
Keep at least 1 in. (25 cm)
between sensor and pipe
wall. If clearance is too small,
calibrate the sensor in place.
Ensure that the sensor is
completely submerged in liquid to the flange. Mounting
the sensor in a vertical pipe
run with the flow from bottom
to top is best. If the sensor
must be mounted in a horizontal pipe run, orient the
sensor in the 3 o’clock or 9
o’clock position.

WARNING
Before removing the sensor, be absolutely certain
that the process pressure is reduced to 0 psig and
the process temperature is lowered to a safe level!
CAUTION
The wetted sensor materials may not be compatible
with process com position and operating conditions.
Application compat ibility is entirely the
responsi-
bility of the user.
