Sensor Replacement Preparation and Inst allation
These instructions apply to wafer-, flanged-, and dual-style flowmeters.
Some additional instructions are included for wafer-style flowmeters.
• Suction or compressed air device
• Small, soft bristle brush
• Cotton swabs, moistened with water or appropriate cleaning agent

Wafer-style flowmeters, sizes 6- and 8-inch (150 and 200 mm):
Rotate the sensor cable 180° while firmly grasping sensor just
below the first coil.
All other flowmeters:
It may be necessary to temporarily bend the sensor cable coil aside in order
to install the sensor nut.

• Remove loose particles using a suction or compressed air device.
3. Clean the sealing surface. See Figure 2.
Sealing surface –
provides a secondary seal in
the event that process fluid
should corrode through the
meter body and enter the
sensor cavity
CAUTION
Do not scratch or damage any part of
the sensor, sensor cavity, or sensor nut
threads. Damage to these parts may
require replacement of the sensor or
meter body, or render the flowmeter
dangerous.
