The Loop Leader+ 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.
Finally, the PD4-6628 is an intrinsically safe version that
can be installed in hazardous areas.
