    • US Marine Flexi-Sensor Flexible Water / Waste Sender is a rugged water or waste sending unit that is field replaceable, without breaking the sender to tank seal
    • US Marine Products has taken the proven float and reed switch technology to a whole new level
    • Innovative design solutions with the Marine Industry in mind
    • The insert consists of multiple resistors and over-molded reed switches affixed to a flexible PC Board.
    • To make these senders more durable USMP has replaced the standard glass reed switch with plastic over-molded switches
    • The over-molding process protects the fragile glass shell that encases the switch contacts
    • If the glass is broken from shock or vibration, this could lead to inaccurate or no gauge readings at all
    • The patented design includes a Flexi-Sensor insert.


    • Durable: Shock resistant
    • Field Serviceable without breaking tank seal
    • Stem Material: Stainless Steel
    • Mounting:
      • (5) Hole Flange
      • 1-1/2" NPT
      • 2" NPT
    • Resistance Range:
      • 30-240 Ohms - Works with most fuel gauge brands
      • (Other Ranges: 0-9 Ohms, 0-180 Ohms, and 0-5 Volt sensors available by special order)
    • Float Material:
      • Buna-N (Fuel)
      • Polypropylene (water)

    Note: Some European made gauges may use a different Resistance Range. Check with the manufacturer.

    Note: Element (only) replacement in an existing installation, requires only 3" clearance; making future maintenance easy. Additional clearance is necessary for placement of the solid stainless steel Stem sleeve when installing a new Flexi-Sensor System in an existing tank.
