Go with the Helios PD2-6001 when you prefer to read level in feet and inches instead of the more common decimal format. This unique display will read up to 99 feet, 11 & 15/16s inches on the upper line. The lower line can display a tag or volume, even from non-linear tanks such as round horizontal ones. The PD2-6001 makes a great outdoor tank side indicator because its display is bright enough to read in direct sunlight and it will operate from -40 to 150°F. The PD2-6001 can also be equipped with a 4-20 mA output as well as four relays that can be used for alarming or controlling applications, including pump alternation control.
