The flow through sensor/sample loop must be installed according to the following
guidelines:
Mount the sensor on a vibration-free, vertical surface so that the sensor tubing
inlet connection is at the bottom and the outlet is at the top. The vertical
orientation will prevent air bubbles from being trapped in the sensor.
Install a shut-off valve at the beginning of the sample loop so that the system
may be shut off quickly if necessary.
If a sample pump is to be used, it must be installed last, after the flow through
sensor and the cooling coil or plate, if applicable.
Other installation guidelines which may be helpful in the overall system:
Mount the sensor as close to solution as possible. Keep tubing distances to the
sensor inlet as short as possible to avoid hydraulic lag time. Maximum
recommended length of tubing from solution to sensor is 25 feet. If this is not
possible, see Application Notes below.
The solution inlet should draw sample from an area of good solution movement
in order to respond quickly to chemical additions. However, the solution inlet
should not draw too near to where the chemistry is added to avoid artificial
'spikes' in concentration.
The solution discharge should be open to atmospheric pressure in order to ensure
proper flow.
The cable connector to the controller is keyed, do not force!
