SAFETY PRECAUTIONS
About this Manual: PLEASE READ THE ENTIRE MAN-
UAL PRIOR TO INSTALLING OR USING THIS PRODUCT.
This manual includes information on the Switch Pro™ with
Compact Junction Box: AU15-_13_ and AZ18-113_. The units
are identical except for the material of construction and the
sensors technology.
User's Responsibility for Safety: Flowline manufactures
a wide range of liquid level sensors, controllers, and mounting sys-
tems. It is the user's responsibility to select components that are
appropriate for the application, install them 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: Use a proper sealant
with all installations. Never overtighten the components. Always
check for leaks prior to system start-up.
Material Compatibility:
Polypropylene (PP, a polyolefin): Sensor, Junction Box.
Perfluoroalkoxy (PFA, Teflon®): Sensor (AU15-213_ only).
Ryton (glass filled): Vibration Sensor Only.
Make sure that the application liquids are compatible with the
materials that will be wetted. To determine the chemical compati-
bility between the components and its application liquids, refer to
the Compass Corrosion Guide, available from Compass
Publications (phone 858-589-9636).
Temperature and Pressure: Switch Pro™ is designed for
use in application temperatures up to 90° C (194° F). The Vibration
and Ultrasonic packages are designed for pressurized applications
up to 150 psi (10 bar).
Wiring and Electrical: Electrical wiring of any liquid level
control system should be performed in accordance with all applic-
able national, state, and local codes. Take care not to cut or break
the outer insulation jacket of wiring that may be immersed while
routing cables in the Switch Pro™ system. Such breaks of the liq-
uid seal of the sensor system may lead to component failure.
Flammable, Explosive and Hazardous Applications:
Switch Pro™ may be used within flammable or explosive applica-
tions only if the associated components are rated intrinsically safe
for such use. In hazardous applications, use redundant measurement
and control points, each having a different sensing technology.
Make a Fail-Safe System: Design a fail-safe system that
accommodates the possibility of system or power failure. In criti-
cal applications, Flowline recommends the use of redundant back-
up systems and alarms in addition to the primary system.
About Switch Pro™: Flowline’s Switch Pro™ with Compact
Junction Box Assembly is an single-point mounting system for
installing one level sensor horizontally within a tank. The compact
junction box features termination for the various wires from each level
switch as well as a 1/2” conduit connection. Switch Pro™ mounts hor-
izontally through a standard 3/4" NPT fitting.
Level Switches: Switch Pro™ includes
a single level switch used to identify it’s own
unique wet / dry condition. The technologies
used to indicate level are either Ultrasonic or
Vibration. Each technology features a unique
wiring/power configuration (Ultrasonic and
Vibration technologies require 12 to 36 VDC
power for operation, see below). The switch
is terminated in the Compact Junction Box.
The Compact Junction Box provides a 1/2”
Conduit connection and 6 poles for wire ter-
mination.
