The new YPP6801 explosion-proof level meter brings modern design, easy readability, and enhanced functionality to hazardous areas around the world in a way never seen before. The YPP6801 features a clearly labeled feet and inches display. The feet and inches display is easily read and understood, providing quick and easy to comprehend information to operators. The meter can display in eighths or sixteenths of an inch. It includes a volume scale display feature and can be seen under varied lighting conditions, from wide angles, and from a distance. Spend a few minutes reviewing the features described in the graphic above and see how the YPP6801 is the ideal level meter for your operation!
Key Features
Easy to Understand Feet & Inches Display
The upper display is 0.6" high and shows clearly labeled feet and inches up to 399 feet, 11 and 15/16 inches. The high contrast, backlight LCD display is easy to read from far away and under various lighting conditions. Feet and inches are clearly labeled. Fractions of an inch may be displayed as eighths, sixteenths, or turned off, displaying only full feet and inches.
20-Segment Tank Level Indicator
A 20-segment tank level indicator gives a clear indicator of height at a glance. When a high level alarm is triggered, the tank level indicator will flash the segment indicating the alarm level. High and low level alarm indicators located with the tank level indicator will flash to alert an operator to the alarm condition. The tank level indicator may be scaled independently of the analog input scale, so the tank indicator may display as full at less than 20 mA. This is ideal for level transmitters that output less than 20 mA at the maximum height of the tank or pit depth.
Lower Display for Tag, Volume, or Percent
The lower display is 0.4" high and shows either a custom tag, volume, or percent full with seven alphanumeric characters. A custom tag is programmable for any seven alphanumeric digits. The 14-segment display makes the tag easy to read, and it can include lower and upper-case letters. This is ideal for identification or material labels. Volume may be displayed from 0 to 9999999, with or without an alternating tag. Percent full may also be displayed, with or without an alternating tag. The percent is clearly labeled with PCT.
Through-Glass Buttons
The YPP6801 is equipped with four sensors that operate as throughglass 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 YPP6801 really shines here. The copper-free (0.3%), smooth, die-cast aluminum NEMA 4X (IP68) enclosure is finished with a corrosion resistant epoxy coating that literally does make the YPP6801 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.
Wide Viewing Angle
The window and display module have been optimized to provide a wide viewing arc of approximately 80°, nearly twice

Environmentally Tough Yokogawa meters not only look 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, as well as high impact, corrosion and electrical interference. The extensive, worldwide agency approvals means they can be installed in virtually any environment
Perfect & Secure Fit Every Time The internal cast rails ensure the YPP6801 assembles together perfectly, quickly and securely; components line 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.
