About Switch-Pro™:

  Flowline’s Switch-Pro™ with Compact Junction Box 

Assembly is a 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 horizontally through a standard ¾" adapter.  

Level Switches:

 Switch-Pak™ includes a single level switch used to identify its 

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 requires 12-36 VDC power for operation and Vibration 
require 12 to 30 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 termination.
