Installation
To maintain the system’s weighing accuracy, make sure that the support steel will not
deflect more than 1/16 inch under full working load.
General Procedure
1. Position the tension weigh modules around the tank so that each will support an
equal portion of the tank’s weight (see Figure 11-2). Make sure that the upper and
lower support brackets line up with these positions.

2. Connect each weigh module clevis to an appropriately sized threaded rod with a
jam nut on it. See Table 11-1 for clevis thread sizes. Tighten the jam nut against the
clevis to prevent the threaded rod from turning.
