Intrinsically Safe Flow Display Meters with Cutting-Edge Features.

The Precision Digital Loop Leader+ is an intrinsically safe loop-powered meter designed for tough operating conditions. Its large dual-line display features a 2.8″ 5-digit top display that displays the flow rate, and a 1.5″ 8-character bottom display that can display the units of measure or a tag. A 20-segment bargraph is also included to provide a visual representation of the flow rate.

For ease of use, the PD4 is available in two configurations: display only, and with two solid-state relays and 4-20 mA analog output. All models come equipped with two open collector outputs for alarm indication and remote contacts for convenient remote operation.

Programming and setup are made simple with the free PC-based MeterView XL software, which connects to the meter via a micro USB cable. The software allows users to save configuration files for later use, and also provides power to the meter during programming.
