3.10 Weigh Station

 NOTE Standard on X-1020 Dispensing Systems; option on the X-1010.

The weigh station (Figure 3-21) is used to perform periodic mass flow calibrations. The weigh station

consists of a small reservoir containing a disposable plastic cup and sheet metal wiper (banjo wiper) that

rests on a sensitive electronic balance (scale). The dispensing valve needle tip/nozzle is inserted into the

top of the weigh station lid, fluid is dispensed onto the banjo wiper, and the scale weighs the fluid. The

data from the scale is reported to the Fluidmove software. Refer to Section 6 – Maintenance for the cup

and wiper replacement procedure. Refer to Section 7 – Specifications for scale performance

specifications.

3.11 Purge Station

The Purge Station (Figure 3-21), consists of a small reservoir that contains a disposable plastic cup and is

attached to a vacuum generator. Air flowing through the purge boot into the cup removes excess fluid on

the dispensing valve needle/nozzle. Refer to Section 6 – Maintenance for the purge boot and cup

replacement procedure.
