PD2-6001 Helios Feet & Inches Level Meter

Brand: Precision Digital Corporation

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 65° C (-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.
