CAUTION
For a flowmeter with fluorocarbon PFA lining,
it is possible that the nuts may loosen as time
passes, so tighten them regularly. Be sure to
tighten the nuts according to the prescribed
torque values. Tighten them diagonally with
the same torque values, step by step up to the
prescribed torque value.
