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.

APPLICATION COMPATIBILITY

MODEL 228 INSTALLATION

INSTALLATION

Keep at least 1 in. (2.5 cm) between the sensor and pipe walls. If the clearance is too small, calibrate the sensor
in place. Ensure that the sensor is completely submerged in liquid. 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.

WIRING

Keep sensor wiring away from ac conductors and high current demanding equipment. Do not cut cable.
Cutting the cable may void the warranty.
