The PD6928-GP loop-powered flow rate/totalizers include a NEMA 4X, IP66 plastic enclosure and can be installed in a variety of harsh operating environments to provide convenient and informative display of any 4-20 mA signal. One of the most convenient features of these instruments is their dual-line display which is typically used to display the flow rate on the 5-character alphanumeric top display and flow total, flow grand total, or a 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 four CapTouch through-window buttons located on the front of the meter provide a convenient way to operate the meter 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.

The ProtEX-RTP PD6830 is an explosion-proof flow rate/totalizer that can display flow rate and total from a pulse output flowmeter. Its display has a five digit upper line for rate, a seven alpha-numeric character lower line for total, and comes standard with a backlight.

The ProtEX-RTP carries all major approvals including:

•  FM Approved as Explosion-Proof / Dust Ignition-Proof / Flame-Proof •  CSA Certified as Explosion-Proof / Dust Ignition-Proof / Flame-Proof •  ATEX and IECEx Certified as Explosion-Proof

It can be powered from an included battery or a 24 VDC external power supply. Some features that really make the PD6830 flow rate/totalizer stand out are its automatic unit conversions from flowmeter k-factor units, ability to log up to 1024 data points, and SafeTouch through-glass buttons. These buttons allow the PD6830 to be programmed and operated through the glass, thus eliminating the need to remove the cover in a hazardous area.

The ProtEX-FarVu PD6870 is a rugged, explosion-proof, loop-powered meter with 1" display digits ideal for demanding applications in hazardous areas or in the harshest environmental conditions.

The ProtEX-FarVu 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 Explosion-Proof

The PD6870 is available in either an aluminum or stainless steel enclosure with ¾" or M20 connections. It will operate down to -40°C and is approved for installation in areas where the temperature gets as cold as -55°C, however, the display will cease functioning.

The PD685 is an easy to use, loop-powered indicator, certified by CSA, ATEX and IECEx as intrinsically safe. The PD685 carries international certifications under both the Class/Division System and Zone System, and is thereby suitable for use in gas and dust hazardous areas worldwide. For Division 2 applications where intrinsically safe interfaces are not needed, the PD685 is able to be installed without barriers! To achieve this ability, the PD685 underwent a special 'nonarcing assessment' under the UL 121201 and CSA C22.2 No. 213 standards, and was determined to be a device incapable of causing an ignition on its own. The PD685 is wellsuited for both indoor and outdoor applications and carries a variety of environmental ratings, including NEMA 4, Type 4X and IP67.

The PD685 can be seen from considerable distance in bright sunlight or dimly lit areas when the standard backlight feature is activated. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area. The meter gets all of the power it needs from the 4-20 mA loop and its 1 V (4 V with backlight) drop results in a minimal burden on the loop. The meter features a wide -40 to 75°C operating temperature range and is available with a ½" conduit hole in a location of your choice for easy installation. Calibration is a quick two-step process involving the adjustment of only two sets of coarse and fine, non-interacting potentiometers.
