Figure 2.1
Prior to installing a PVDF-stem MPXI-F, the interior, mid-column temperature of the tank must be meas-
ured to determine the amount clearance needed at the bottom of the probe for thermal expansion. See
Figure 2.1
1. Determine interior, mid-column temperature in °F.
2. Determine interior tank height from top of probe mounting to tank interior bottom, in inches.
3. Use formula in Figure 2.1 to determine necessary clearance from bottom of probe to interior tank
bottom.
4. If necessary, adjust placement of slide mount on probe to accomodate required clearance.
Contact factory with any PVDF-stem thermal expansion requirement questions.
