About this Manual: PLEASE READ THE ENTIRE MANUAL
PRIOR TO INSTALLING OR USING THIS PRODUCT. This
manual includes information on the XP8_-0 Ultrasonic Level
Transmitter from FLOWLINE. Please refer to the part number
located on the transmitter label to verify the exact model configuration which you have purchased.
User’s Responsibility for Safety: FLOWLINE manufac-
tures a broad range of level sensing technologies. While each of
these sensors is designed to operate in a wide variety of applications, it is the user’s responsibility to select a sensor model that is
appropriate for the application, install it properly, perform tests of
the installed system, and maintain all components. The failure to do
OVERVIEW
Step Three
A. Application: The explosion proof ultrasonic transmitter provides non-contact level detection up to 32.8’ or 10m. The transmitter
is well suited for a wide range of corrosive, waste and slurry type
media, and is broadly selected for atmospheric bulk storage, day tank
and waste sump applications.
B. Part Number: The part and serial numbers are located on the
wrench flat. Check the part number on the product label and confirm
which of the below model configurations you have purchased:

so could result in property damage or serious injury.
Proper Installation and Handling: Only properly trained
staff should install and/or repair this product. Never overtighten
the transmitter within the fitting. Always check for leaks prior to
system start-up.
Opening The Enclosure: EchoSafe is designed to be
installed in a hazardous areas and, when installed, do not open
the unit while power is applied. Always disconnect the power
source from EchoSafe prior to opening, programming, installing, or removing it. Additionally, ensure that electrical wiring,
fittings and mechanical connections conform to all applicable
electrical codes.
Material Compatibility: The XP8_ series enclosure is made
of a Aluminum. The transducer is made of Polyvinylidene Fluoride
(PVDF). Make sure that the model which you have selected is
chemically compatible with the application media and it’s environment.
Enclosure: While the transmitter housing is liquid-resistant the
XP8_ series is not designed to be operational when immersed. It
should be mounted in such a way that the enclosure and transducer
do not come into contact with the application media under normal
operational conditions.
Make a Fail-Safe System: Design a fail-safe system that
accommodates the possibility of transmitter and/or power failure.
FLOWLINE recommends the use of redundant backup systems
and alarms in addition to the primary system.
Handling Static-Sensitive Circuits/Devices
When handling the transmitter, the technician should follow
these guidelines to reduce any possible electrostatic charge
build-up on the technicians body and the electronic part.
1. Always touch a known good ground source before handling the
part. This should be repeated while handling the part and more
frequently after sitting down from a standing position, sliding
across the seat or walking a distance.
2. Avoid touching electrical terminals of the part unless making connections.
