Step One
SAFETY PRECAUTIONS
About this Manual:
PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS
PRODUCT. This manual includes information on the EchoPro
®
Radar Level Transmitter from FLOWLINE.
Please refer to the part number located on the sensor label to verify the exact model, which you have
purchased.
User’s Responsibility for Safety:
Flowline manufactures 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 so could result in property damage or
serious injury.
Proper Installation and Handling:
Only professional staff should install and/or repair this product. Never
over tighten the sensor within the fitting. Always check for leaks prior to system start-up.
Wiring and Electrical:
A supply voltage of 21.6 to 26.4 VDC is used to power the EchoPro
®
. Electrical
wiring of the sensor should be performed in accordance with all applicable national, state, and local codes.
Material Compatibility:
The enclosure is made of either Aluminum or 316 Stainless Steel (refer to sensor
part number). The antenna is made of Stainless Steel (SS), Polytetrafluoroethylene (PTFE), Polyvinylidene
Fluoride (PVDF) or Nylon (PA66) with a Viton seal (refer to sensor part number). Make sure that the model,
which you have selected, is chemically compatible with the application media.
Enclosure:
The sensor housing is media-resistant, but is not designed to be operational when immersed.
Mount the sensor in such a way that the enclosure and antenna do not come into contact with the application
media under normal operational conditions. The enclosure has a cover that provides access to the push
button display module and terminal strip for wiring. To open the enclosure, you will need to twist the cover
counter-clockwise. Before closing the enclosure, make sure that the enclosure gasket is properly seated, and
that any conduit fittings, cable connectors or plugs are installed correctly and sealed.
Note: If using the
Flowline LM90-1001 (liquid tight fitting) on the ½” conduit, the cable minimum is 0.170” (4.3mm) and the
maximum is 0.450” (11.4mm).
Make a Fail-Safe System
: Design a fail-safe system that accommodates the possibility of sensor and/or
power failure. FLOWLINE recommends the use of redundant back-up systems and alarms in addition to the
primary system.
Flammable, Explosive or Hazardous Applications
:
EchoPro
®
is approved for use within intrinsically
safe applications ONLY and should NOT be used within classified hazardous environments.
Handling Static-Sensitive Circuits and Devices:
When handling the instrument, the technician should
follow the below guidelines to reduce the possibility of an electrostatic charge build-up on the technician’s body
from being transferred to the electronic part. Always touch a known good ground source before handling a
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. Avoid touching electrical terminals of the part unless
making connections. DO NOT open the unit cover until it is time to work on the part.
