80 PCB007 MAGAZINE I SEPTEMBER 2024 nuts (two nuts for locking), the specific grav- ity setpoint will be from 1.21 to 1.32 ±0.002 SG units (but it can be designed to be wider or narrower in range). Note: is chart in Figure 2 is set up for the GEM level switch and the CPVC adjustment rod seen below the chart. If the level switch, nuts, or rod have any other geometries or materials, the chart will not be accurate. You will need to change the BASIC program's vari- ables (Figure 3) for the displacement of the switch, nuts, and rod as well as the weight of the rod and nuts, as these variables determine the volume displaced (buoyancy force) and the moment from gravity. Remember, this sen- sor is entirely submerged in the etchant. Figure 2: Operation and design chart for the GEM contact float and above CPVC rod and nuts.
