: Do not connect the sensor outlet plumbing to the fluorometer outlet plumb-
ing – this may impair the flow through the fluorometer when inlet flow pressure varies.
Plumb using ball valves provided. Inlet
water from recirculating system must be
at 5 GPM or greater.

• There are two outlet connections on the 3D TRASAR system.
a. The top ½” fluorometer outlet must have a minimum flow rate of 0.5 gpm.
b. The bottom ¾” sensor outlet must have a minimum flow rate of 4.5 gpm.
• Plumb the ½” female NPT fluorometer outlet to one of the following:
a. Cooling tower basin
b. Drain
c. Lower pressure point in the system (minimum differential of 20 psig)
• Plumb the 4.5 gpm sensor outlet (3/4” female NPT) to one of the following:
a. Inlet of the Pellet Feeder (preferred if Pellet Feeder is being used)
b. Cooling tower basin
c. Lower pressure point in system (minimum differential of 20 psig)
d. Drain (not recommended)
