OVERVIEW
The new ProtEX-RTP PD6830 explosion-proof rate/totalizer brings modern design, easy readability, and enhanced functionality to hazardous areas around the world in a way never seen before. Competitors have lost sight of the fact that the primary thing customers want to do with meters such as these is to look at them. Customers want a meter that looks nice so they can be proud to install it in their facility. And they want a meter with a display that provides the important information about their process, can be seen under varied lighting conditions, from wide angles, and from a distance. The PD6830 delivers all these and more. Spend a few minutes reviewing the features described in the graphic below and you will see how!
KEY FEATURES
Informative & Easy to Read Display
The high contrast, backlight LCD display is easy to read from far away and under various lighting conditions. The upper display is
0.7" high and shows 5 digits of flow rate. The lower display is 0.4" high and shows either flow total or a tag with 7 alphanumeric characters. And best of all, the display is mounted right up against the glass so it can be seen from a wide viewing angle.
Through-Glass SafeTouch® Buttons
The PD6830 is equipped with four sensors that operate as through glass buttons so that it can be programmed and operated without removing the cover (and exposing the electronics) in a hazardous area. These buttons can be disabled for security by selecting the LOCK setting on the switch located on the connector board in the base of the enclosure. To actuate a button, press one finger to the glass directly over the marked button area. When the cover is removed, four mechanical buttons located next to the sensors are used.
Modern, Sleek and Practical Enclosure
The first thing customers notice about a product is its enclosure and the ProtEX-RTP really shines here. The copper-free (0.30%), smooth, die-cast aluminum NEMA 4X (IP68) enclosure is finished with a corrosion resistant epoxy coating that literally does make the ProtEX-RTP shine. The built-in mounting flanges make for convenient wall or pipe mounting and there is even a slot on the back of the enclosure for centering on the pipe. There are two ¾" NPT conduit holes for wiring and one ¾" NPT hole for flowmeter connection.
Wide Viewing Angle
Customers can't always look at the display from straight on, so the window and display module have been optimized to provide a wide viewing angle of approximately +/- 40°; nearly twice the competition! Remember, the PD6830 is designed to be looked at.
Perfect & Secure Fit Every Time
The internal cast rails ensure the ProtEX assembles together perfectly, quickly and securely; and everything lines up for optimal viewing every time. There are no standoffs to worry about breaking or getting out of alignment. Two spring-loaded, self-retaining, thumbscrews make the assembly a snap, while pressing the LCD as close to the glass as possible to improve wide angle viewing.
Environmentally Tough
The ProtEX™ Series not only looks great with their modern, smooth die cast aluminum enclosures, but they can be installed virtually anywhere. The NEMA 4X / IP68 enclosure provides serious protection from the elements, high impact, corrosion and electrical interference and the extensive, worldwide agency approvals means they can be installed virtually anywhere.
TOTALIZER CAPABILITIES
Gate Function for Slow Pulses
The gate function provides for rate display of slow pulse rates. Using the programmable gate, the meter is able to display pulse rates as slow as 1 pulse every 999 seconds (0.001 Hz). The gate function can also be used to obtain a steady display reading with a fluctuating input signal. There are two settings for the Gate, low gate ( ) and high gate ( ).
Totalizer Conversion Factor
Total Conversion Factor is used to convert to a different unit of measure for the total display. For example, to display rate in gallons and total in liters, enter a Conversion Factor of 3.7854. When rate and total units are the same, the Conversion Factor should be 1.0000.
Total Reset
The total can be reset either manually via the front panel RESET button or external contact; or automatically using a programmed setpoint and delay time. Total reset can also be disabled.
Wide Input Signal Selection
The PD6830 is designed to handle a wide variety
of inputs, including: pulse, open collector, NPN,
PNP, TTL, or switch contact. The input can handle
up to a 30 kHz signal without degradation. It can readily discern inputs with pulse widths as small
as 16 µs. Inputs are conveniently set up on the
display module by simply moving switches to the
desired options.
METER CONFIGURATION
K-Factor Scaling
The meter may be scaled using the K-Factor function. Most flowmeter manufacturers provide this information with the device. Enter the K-Factor  menu and select the decimal point with highest resolution possible and program the K-Factor value (i.e. pulses/gal). The meter will automatically calculate the flow rate using the K-Factor and the time base selected.
Custom Meter Scaling
In lieu of K-Factor scaling, the meter can be scaled to any span relative to the input pulse rate span (i.e. if you knew the pulse input span for gallons but wanted to display the rate and total in liters). No external signal is required.
Live Input Calibration
In lieu of K-Factor and Custom Meter Scaling, the meter can be calibrated with a precision signal source. While applying a precision signal, the relative scale value is entered via the front panel. This is done at any two points along the scale. Using this method, an operator can set a "best fit straight line" for non-linear input spans.
Multi-Point Linearizer
Up to 32 linearization points can be selected under the Linear function. The multi-point linearization can be used to linearize the display for non-linear signals such as non-linear flows, and for end-point correction on flow meters. These points are established via direct entry  or with an external calibration signal  .
Alternating Total/Tag Display
The meter can be configured so that the lower display automatically toggles between displaying the assigned tag name and total every 10 seconmds.

ADDITIONAL FEATURES
Password Protection
A 5-digit password prevents unauthorized changes to the programmed parameter settings. The lock symbol is displayed to show that settings are protected. If the meter is password protected, the meter will display the message LOCKED when the Menu button is pressed.
Alarm Indication
The PD6830 can be configured to have a high or low rate alarm indicator, or a total alarm set point indicator. When in alarm mode, the display will flash, and a HI or LO symbol is displayed. The alarm is acknowledged by pressing the ENTER/ACK button.
Pulse to 4-20 mA Retransmission
Use the analog output to retransmit the pulse input signal to the commonly used 4-20 mA form. Available on the PD6830's -ATA, -BTA, and -CTB models. Output can be scaled to represent all, or part, of the actual input span. Shown below with switch contact input on a PD6830-APA. See manual for details.
INSTALLATION
Direct Mounting
The PD6830 is designed to easily mount directly to a flowmeter. The example below shows it mounted to a turbine flowmeter. This particular ProtEX-RTP model (BM0) is battery-powered. Even though battery-powered, it does have a backlight; but to conserve battery power, it only turns on while SafeTouch® buttons are in use.
Installation Flexibility
The PD6830's rotatable display/meter along with three available conduit connections provide for numerous installation options. The display can be rotated in 90° increments. Rotate it 90° for horizontal mounting. Wiring can be routed to the most convenient conduit connection(s). One metal conduit plug is supplied per unit. Additional plugs are available (PDAPLUG75) if needed.
Easy Wiring & Service
Field wiring is made to an easily accessible screw terminal block at the base of the enclosure and there is plenty of room inside the enclosure to do the wiring. The terminal block is clearly marked to ensure proper wiring. The meter module connects to a detachable ribbon cable so it can be easily removed for service, while keep all the field wiring intact.
FLEXI-POWERED
There are ProtEX-RTP models that can be powered by battery, DC with battery back-up, DC only, or the output-loop. Under nominal battery operating conditions, the battery life is approximately 5 years. As an unused back-up, the life is the shelf-life of the battery (up to 20 years). When powering the PD6830-CTB by the output loop, the output load impedance must not exceed 700 Ω @ 24 VDC excitation (See Specifications for details).
CONNECTIONS
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 a terminal block at the base of the enclosure. Grounding connections are made to the two ground screws provided on the base – one internal and one external.
