Chapter 6. Transducer Replacement
IMPORTANT: Do not reuse the old o-rings. Replace them with new o-rings, as specified in Table 1 on page ciii.
Use the components described in the previous section, to install the new transducers as follows:
1.
Lubricate and install three new o-rings in the T11 holder (see Figure 76 below and Table 1 on page ciii).
Note:
The item numbers shown in Figure 76 below correspond to those listed in Table 1 on page ciii.
2. Inspect the sealing surfaces of the transducer mount and the T11 transducer that is to be inserted into the meter
body to insure there is no damage to either surface.
3.
Lubricate the shaft of the transducer with a spray lubricant that is safe for the o-rings.
4. Carefully push the transducer into the holder until the flange contacts the face o-ring seal, being careful not to
disturb the o-rings.
