Dwyer Instruments” Series DTP is a manual, no-electricity-required indicator that is compact and provides uninterrupted liquid level indication for use in storage tanks or vessels. With a sturdy, lightweight design, the DTP is a good fit for 30 or 55 gallon tanks. Stem and mounting fixtures are available in PVC, PVDF or polypropylene. With a choice of three highly engineered plastic material and large floats, the DTP provides rugged durability in almost any chemical tank. The float and stem are the only parts of the DTP that make contact with the liquid, so the indication tape is always clean and easy to read. A custom configurable DTP is available in lengths ranging from 6 in (15.2 cm) up to 6 ft (182.9 cm). This level indicator is ideal for quick readouts taken periodically. The DTP is accurate to 1/16 of an inch or one millimeter and is particularly useful in remote areas where power is unavailable, or undesirable.
