Frequently Asked Questions
What is Tank Tender and how does it measure tank levels?
Tank Tender is a precision tank measuring system for boats that reads liquid level without electricity. A hand pump pressurizes a tube at the bottom of the tank, and the user reads the level from the resulting pressure. Ron Hart founded Tank Tender in 1982.
Which boat tanks can Tank Tender monitor?
Tank Tender is engineered to monitor potable water, diesel fuel, and blackwater/greywater holding tanks. Because the system relies on air displacement through semi-rigid $1/8"$ nylon tubing and rigid internal dip pipes, there are no electrical sensors or floats inside the tank to corrode or foul. Note: Standard Tank Tender installations are designed for diesel, water, and waste; verify specific plumbing considerations with Hart Systems prior to installation near volatile gasoline storage.
Does Tank Tender work without electrical power?
Tank Tender works without electrical power because a manual hand pump pressurizes a tube at the bottom of the tank. The user reads the liquid level from the resulting pressure, which makes the system practical for marine environments where reliability is critical and electricity-free measurement is valued.
