SAFETY PRECAUTIONS
About this Manual: PLEASE READ THE ENTIRE MANU-
AL PRIOR TO INSTALLING OR USING THIS PRODUCT. This
manual includes information on the Switch Pro™ with Compact
Junction Box (Flow): AT1_-_63_ and AG1_-_63_. 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 sensors, controllers, and mounting systems.
It is the user's responsibility to select components that are appro-
priate 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.
Ryton: Sensor (A_1_-363_ only).
Polyvinylidene Fluoride (PVDF): Sensor and Switch Pro™ fitting.
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 50° C (140° F). The assem-
bly is also designed for pressurized applications up to 150 psi (10
bar).
Wiring and Electrical: Electrical wiring of any liquid or gas
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:
The AT17-_63_, AT18-_63_, AG17-_63_ and AG18-_63_ Switch
Pro™ should not be used within classified hazardous environ-
ments.
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 flow sensor within a pipe or fume. The compact junc-
tion 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.
Flow Switches: Switch Pro™ includes a
single flow switch used to identify it’s own
unique flow / no-flow condition. The tech-
nologies used to indicate flow is Thermal
Dispersion. Both the liquid and gas configu-
rations feature similar wiring/power configu-
ration (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 con-
nection and 6 poles for wire termination.
