3.62 Installation (Inline Sensor Plumbing)
Please refer to the photos below which illustrate the recommended inline sensor plumbing
installation using 1” Schedule 40 or 80 PVC pipe. The exact layout is determined by site
requirements or limitations. However, the layout shown will ensure the electrode tip stays
submerged and minimizes the opportunity for bubbles to collect at the electrode tip. Flow is from left
to right
.
The sensor orientation should be between 45 and 80
degrees above horizontal to prevent air bubbles
becoming trapped near the ion selective membrane or
on the sensor tip. Sensors should NEVER be mounted
with the sensor tip pointing straight down, horizontally,
or pointing up as this may cause a bubble on the
sensor tip and lead to erratic or unreliable readings.
DO NOT OVERTIGHTEN THE SENSOR AS THIS MAY
CRACK THE FLUORIDE ISE CRYSTAL
Pressure must be stable and should not exceed 20 PSIG,
if needed install a pressure reducing regulator.
Recommend flow rate is about 2-3 GPH in 1” schedule 80
PVC pipe, or 1-foot /sec. velocity. Flow rate must be
stable. Open the influent ball valve on the left fully, and
use the backpressure valve on the right to control flow
and provide back pressure. Optionally a flow rotometer
can be substituted for the flow control valve to more
easily set the flow to the desired rate.
