These 1/8 DIN loop-powered meters display level in feet & inches and are available in safe area configurations with UL electrical safety approval and hazardous area approval with UL, ATEX & IECEx Intrinsically safe and nonincendive (UL only) approvals. One of the most convenient features of these instruments is their dual line display which is typically used to display the level in feet and inches on top line and either volume, units or a tag on the 8-digit alphanumeric bottom line. The 20-segment bargraph provides another convenient way to indicate the level. They can be easily programmed via the four front panel buttons or free PC based software. All models come equipped with two open collector outputs and are available with two solid state relays and 4-20 mA analog output options.
