The new YPP6820 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. 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 YPP6820 delivers all these and more. Spend a few minutes reviewing the features described in the graphic above 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 Buttons

The YPP6820 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 YPP6820 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 YPP6820 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.

Isolated Open Collector Output

The isolated open collector output on the YPP6820 may be assigned for use with the alarm or totalizer (pulse output). The rating of the output is 30 VDC @ 150 mA max.

Perfect & Secure Fit Every Time

The internal cast rails ensure the YPP6820 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.

Totalizer Capabilities

Totalizer Pulse Output

The totalizer pulse output function requires use of the open collector output. It will output a pulse at a user adjustable pulse rate, and can be scaled with a K-factor of between 0.0001 and 99999. Example: For 1 pulse every 500 gallons, set the K-factor to 500. This output can be sent to a PLC or counter.

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.
