About Smart Trak
™: Flowline’s Smart Trak™ with Compact Junction Box Assembly is an adjustable
mounting system for installing multiple level sensors vertically within a tank. Mounted through a single point at
the top of the tank, up to 4 different sensors can be located at any depth on Smart Trak™. The compact
junction box features termination for the various wires from each level switch as well as a 1/2” conduit
connection. Smart Trak™ mounts vertically through a standard 2" NPT tank adapter, or on a side mount
bracket (such as the LM50-1001). Unlike prefabricated “trees” or pipes, Smart Trak™ allows you to experiment
with sensor position to account for variations in the point of actuation of each sensor during process testing.
Track:
The track itself is approximately 1" square, and is from 8” to 10' long depending on the A-Dimension.
The track may be cut to length if desired. Four separate grooves run the length of the track, one on each side
of the square. These grooves hold the sensor cars that attach to Flowline sensors, and also serve to contain
the switch cable. The bottom of the track is capped with an end cap.
Level Switches:
Smart Trak™ will include from 1 to 4 level switches used to identify
it’s own unique wet / dry
condition. The technologies used to indicate level are either
Ultrasonic, Buoyancy or Vibration. Each technology features a unique wiring/power
configuration (Ultrasonic and Vibration technologies require 12 to 36 VDC power for
operation, see below). All of the switches are terminated in the Compact Junction Box.
The Compact Junction Box provides a 1/2” Conduit connection and 12 poles for wire
termination (for models AU45-434_ and AZ48-434_, common terminals such as
Positive (+) and Negative (-) power must be shared).
