Liquid level gauges provide an accurate way of measuring the liquid level inside drums in the oil & chemical, petroleum, automobile and other fluid control industries. Raptor Supplies offers a huge range of liquid level gauges from Krueger, Justrite, Oil Safe and Plast-O-Matic. They prevent overfilling & wastage, in addition to measuring flow rate while dispensing in vertical or horizontal positions, using a pop-up indicator display. Krueger liquid level gauges measure the level of liquid in a process tank. These gauges can be used for tank sizes ranging from 6 inches to 12 feet in depth and feature an easily removable bushing which allows threading the bushing into the tank first. Justrite liquid level gauges avoid overfilling & dangerous overflow and polyethylene pop-up gauges provide an economical way to prevent accidents. These polyethylene gauges are used with vertically-stored drums during waste disposal and are protected by chrome-plated housing for use with non-viscous liquids. They come with Buna-N seals ideal for petroleum products and heavy-duty glass tubing permitting clear visual checking of the liquid level.
