When you decide to have your LFE cleaned, please be aware of the various capabilities of calibrating
LFE’s at Meriam. Every calibration includes: 6-8 calibration points [differential pressure 1”-8”H2O], a data
sheet with raw and reduced data, calibration curve, and instruction manual. The procedure numbers are
noted in (parentheses).
