This document is the instruction manual for the Flowline LI23 flow meter. The meter uses a 4-20mA input and can display temperature, humidity, pressure, and liquid level parameters.
The Flowline DataLoop™ LI23 is a 1/8 DIN digital panel meter designed to display any 4-20 mA signal. It features a dual-line alphanumeric LCD with an optional backlight and a 20-segment bargraph. The device operates directly from the current loop, requiring only a 1.5V drop (or 4.5V with backlight), making it suitable for virtually any installation where power is limited.
