    • (4) Stainless Steel Tank Penetration Fittings (TPF)
    • (4) Specially extruded 30" straight nylon tubes pre-attached to Tank Penetration Fittings
    • Mounting hardware
    • Installation manual

    General Features:

    • The Hart Tank Tender uses air pressure to provide accurate level readings (+/-1% at mid-scale on a proper installation) for up to (10) water, diesel and holding tanks
    • No electrical connection necessary
    • Choosing a Tank Tender:
      • As an example, a typical 4-tank installation may measure the levels of (1) Diesel fuel tank, (1) Waste holding tank and (2) Water tanks
    • Gauges are calibrated in inches for diesel and water
    • Monitoring waste holding tanks is possible with the optional "Purge" toggle switch valve
      • The Purge toggle switch valve clears the waste holding tank's Tank Penetration Fitting (TPF) tubes before taking readings
    • System conveniently allows you to check all tank levels with one instrument from one onboard location
    • Simple, completely self-contained pneumatic operation:
      • Select tank to be measured
      • Pump small amount of air through tubing to bottom of the selected tank
      • When air pressure in the tube equals the liquid pressure at the bottom of the tank, gauge displays pressure in inches of liquid
    • Package includes: Tank Tender Gauge with Panel, Nylon Tubing and all fittings required for installation (Some Include Optional Purge Valve)
      • Monitoring waste holding tanks is possible with the optional "Purge" toggle switch valve
    • System components:
      • (1) Instrument panel set up for appropriate number of tanks
        • Gauge Selection – Select gauge with margin of safety regarding tank depth
          • For example, use 30 / 35" gauge if your tank is 20" deep; for a tank that is 40" deep, use 60 / 70" gauge
      • (30') of 1/8" OD nylon tubing per tank (Sold as continuous roll)
      • (1) Stainless steel Tank Penetration Fitting (TPF) per tank with specially extruded 30" straight nylon tube
        • Tank Penetration Fitting Extender
          • Each 60 / 70" Tank Tender system also includes (1) 30" TPF Extender per tank
          • This component consists of a 30" length of straight nylon tube with a stainless steel stiffening wire inside and a brass barb on one end that fits into the end of the TPF tube
          • Additional 30" lengths are available for further extending the TPF for even deeper tanks
      • Mounting hardware
    • System is convenient, reliable, inexpensive and easy to install
      • Tanks can be located up to 1000 ft. from Tank Tender unit
      • System is built with corrosion-resistant materials including brass and stainless steel
