Intrinsically Safe Flow Rate Totalizer

Intrinsically Safe Flow Rate Totalizer

  • 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.

  • The Loop Leader PD6620 is an ATEX and IECEx approved, UL listed, intrinsically safe and nonincendive, loop-powered, 1/8 DIN flow rate/totalizer designed for demanding process control applications. A dual-line display featuring five digits on the top line and eight digits on the bottom line, preprogrammed engineering units, loop-powered backlight with a unique red backlight option for alarm conditions, and optional bargraph display (PD6628) provide a clear and attractive presentation of the process. All models come equipped with two open collector outputs and are available with two solid state relays and a 4-20 mA analog output. These outputs can be programmed for alarm indication, signal retransmission via pulse or analog signal, pump control, and a number of other useful features. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines; the meter gets all of the power it needs from the 4-20 mA loop. The Loop Leader loop-powered rate/totalizer is built in a shallow-depth case with a IP65 front and features loop-powered backlighting and a wide -40 to 158°F (-40 to 70°C) operating temperature range. It doesn't matter if it's in hazardous areas, indoors or outdoors, in bright sunlight or a dimly lit plant, or in an area that is wet, dirty, hot, or cold, the Loop Leader can go just about anywhere.
