 The Loop Leader+ intrinsically safe loop-powered large display flow rate/totalizers can be installed virtually anywhere to provide convenient and informative display of any 4-20 mA signal. One of the most convenient features of these instruments is their large, dual-line display which is typically used to display flow rate on the 2.8" 5-character alphanumeric top display and flow total, flow grand total, or a tag on the 1.5" 8-character alphanumeric bottom display. Both display lines use 14-segment, alphanumeric characters that provide much clearer indication of tags, units, or alarm messages than 7-segment characters do.

 
Further enhancing the display on these instruments is a 20-segment bargraph that also includes a numeric value of the percentage the bargraph represents. Free, PC-based, MeterView XL software that connects to the meter via a micro USB cable is available for programming and setup of the meters.
 
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 and remote contacts. The open collector outputs are useful for alarm indication or pulse output. The remote contacts can be used to remotely operate the four programming buttons, to reset the total, to start/stop a timer/stopwatch, and more. The relays can be programmed for alarm indication, sample, timer, batch control, or stopwatch.
