Floats
Options for rotameter float materials and designs extend flow ranges for different fluids within a given rotameter tube design.
CAUTION: Meters used in gas service are designed to operate at 14.7 psia. Meters used in pressure gas service must be shielded using 3/8” polycarbonate to protect personnel and equipment in the event of tube failure.
