4.3 Plumbing Requirements and Installation
4.3.1 Water supply and drain
The WG-602 FCL requires a pressurized water supply to the flow cell. An isolating
valve must be installed between the main line and the pipe (tube) to the analyzer.
The water supply need to be connected to the pre-filter with a 6 mm (1/4'') feed tube.
The minimum pressure to the analyzer should be 0.5 bar (7 psi) and should not
exceed 1 bar (14.5 psi). Set the right pressure using the pressure regulator that
attached to the outlet of the pre-filter. Pull up the pressure regulating adjusting valve
and set the right pressure by turning the valve. Push down and lock it when finished.
Adjust the flow rate through the acrylic flow cell so the metal float will be in front of
the proximity flow switch. Use the flow regulating valve (on the bottom left of the
acrylic flow cell) to regulate the flow properly. A gravity drain is recommended for the
water outlet from the acrylic flow cell.
NOTE:
The distance from the main pipe to the analyzer should be as short as possible, in
order to minimize the delay time between the water being sampled and the analyzer
measurement.
