correctly. It may take two or three data collection cycles to remove air bubbles from the
sensor's plumbing.
If necessary, a plumbing fitting is available from the manufacturer that will aid in the
removal of air bubbles.
5.11 Bio-fouling prevention
Electrical tape, copper foil tape, and anti-fouling paint will decrease the rate of bio-fouling
on the plastic parts of sensors. The manufacturer supplies an anti-fouling paint kit with
WQM sensors. Instructions for use are detailed below.
Electrical tape
The manufacturer recommends electrical tape such as Scotch
®
Super 33+ or Super 88.
This tape can be used in seawater and can be removed without leaving adhesive residue.
Softer bio-foulants will peel off with the tape. The tape can be put on irregular surfaces.
Adhesive-backed copper foil tape
The manufacturer recommends putting a layer of electrical tape under the copper foil tape
because the adhesive on the copper foil tape is tacky and difficult to remove from the
surfaces of the sensor. One layer of copper foil tape will give good protection for
approximately 6 weeks.
Anti-fouling paint kit
The manufacturer supplies an anti-fouling paint kit with each sensor that has
ECOMINDER
®
paint, tape, a brush, and detailed instructions for application.
ECOMINDER
®
is an alternative to copper-based anti-fouling paint.
5.12 Spare parts
The manufacturer supplies the spare parts listed below so that the user can clean and
maintain the sensor.
