With Just PB & Reset process went off set point

a lot

PB & Reset changed, then Rate had a good effect, process was kept close to set

Calibration

We do not calibrate flow meters/transmitters in this class,

they are done in the advancedPCI-162 class.

Coriolis Meter: Linear, High accuracy, liquids only

Vortex Meter: Linear Medium Accuracy, Steam Flow

Mag Meter: Linear, liquids with solids, waste treatment
