Float and tape gauges, also known as “automatic tank gauges”, have been in the marketplace for over 90 years. This tried and true method works by using a large float inside the tank attached to a negator spring via a perforated tape. The negator spring provides constant tension, which balances the float on the liquid. The perforated tape engages pins on a sprocket wheel that, in turn, drives the counter assembly. Alternatively, when a gauge board is used to display level, the negator spring is replaced by a counter weight system. The liquid level in the tank is displayed on the gauge counter or indicated on the gauge board.
