• Figure 5-8c: Support structure is out of level, applying side forces to the load cell.

A tank scale’s support structure should deflect as little as possible, and any

deflection should be uniform at all support points (see Figure 5-9). Excessive

deflection can cause inlet and outlet piping to bind, creating linearity errors. When

deflection is not uniform, it can cause repeatability errors and zero return errors

due to creep.

1/4” max.

Figure 5-9: Weigh Module Base Support Structure Deflection

In some cases, a tank’s legs will deflect under the weight of the tank (see Figure

5-10a). If the deflection is great enough to affect weight readings, you should

brace the legs to keep them rigid (see Figure 5-10b).
