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. Like all ProtEX products, the PD6830 carries FM, CSA, ATEX, and IECEx approvals for use in hazardous areas. 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.

MeterView EX Software
MeterView EX software allows for programming of the ProtEX-RTP PD6830 and Vantageview PD6730 pulse-input rate/totalizers. The meter connects to a PC with a PDA8068 meter to USB adapter, or skus with the RS-485 option may use an appropriate RS-232 or USB serial converter. This remote programming software allows for all meter settings to be programmed from a PC through an easy to understand interface.
To access the wiring connections, remove the enclosure cover and unscrew the two captive screws that fasten the display module. Disconnect the ribbon cable and remove the display module. Power and signal connections are made to terminal blocks at the base of the enclosure. Grounding connections are made to the two ground screws provided on the base – one internal and one external.
