Tape Level Indicator Requires No Electricity

Madison Company’s TL Series Tape Level Indicators are designed for simple and economical liquid level indication where no electrical power is available. Ideal for 30 or 55 gallon remote and mobile tanks, these devices incorporate a magnetic float and a standard tape measure blade that is sealed in a liquid-tight tube. Only the stem and float come in contact with the liquid, so the tape is always clean and easy-to-read.
The retractable steel tape magnetically latches to the level position of the magnetic float. The liquid level in the tank is determined by sliding the tape out of the stem tube and reading the aligning graduation mark on the tape when the magnetic interlock is felt.
The TL Series includes 3 models: Brass stem and fitting with a BUNA-N float, stainless steel stem and fitting with a polypropylene float and a stainless steel stem and fitting with a stainless steel float, with total lengths of up to 6 feet available. These Madison level indicators are an excellent solution for marine applications, industrial fire extinguishers, chemical drums and underground liquid storage.
