Flow Rate Totalizer

The PD6200 is a member of the ProVu series of 1/8 DIN digital panel meters that is specifically designed to display flow rate and total from an analog output (4-20 mA, 0-5 V, 1-5 V, etc.) flowmeter. It displays that signal on a dual-line, 6-digit display that is available with optional Sunbright® sunlight readable LEDs. Flow rate is typically displayed on the upper line and the cumulative total is displayed on the lower line. The total overflow feature allows up to a 9-digit total and grand total to be displayed. Like all ProVu meters, the PD6200 includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options. ProVu meters can be equipped with up to four internal relays, a 4-20 mA output, and Modbus® RTU serial communications. The PD6200 includes a 24 VDC power supply to drive the flowmeter and can be programmed via the front panel pushbuttons or free MeterView® Pro software.

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 ProtEX+ loop-powered explosion-proof & intrinsically safe flow rate/totalizers can be installed virtually anywhere to provide convenient and informative display of any 4-20 mA signal. They can operate down to -40°C and be installed in areas that get as cold as -55°C, however the display will cease functioning. One of the most convenient features is the dual-line display, typically used to display the flow rate on the 5-character alphanumeric top display and flow total, flow grand total, or tag on the 8-character alphanumeric bottom display. The top display uses 12-segment, and the bottom display uses 14-segment alphanumeric characters for clear indication of tags, units, or alarm messages. Further enhancing the display on these instruments is a 20-segment bargraph.

The ProtEX+ carries all major approvals including:

•  UL Listed as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
•  CSA Certified as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
•  ATEX and IECEx Certified as Intrinsically Safe / Explosion-Proof

Four CapTouch through-glass buttons are available to operate the instrument without removing the cover. 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.

All models come equipped with two open collector outputs and a digital input. There are also models available with two solid-state relays and isolated 4-20 mA analog output options. The relays can be programmed for alarm indication, sample, timer, batch control, or stopwatch.

Go with the Helios PD2-6300 when you want to display both flow rate and total at the same time from a pulse output flowmeter. The PD2-6300 can display both flow rate and total in six full digits and can also be configured to display non-resettable grand total. The PD2-6300's NEMA 4X enclosure, super bright LEDs, and wide operating temperature range make it perfect for outdoor applications.
