MAINTENANCE
The SulfiLogger
™
sensor has no active fouling handling, and the
sensor head therefore needs periodic cleaning. The necessary
cleaning frequency depends very much on the type of wastewater
and on the turbulence around the sensor. Stagnant water gives
ideal conditions for biofouling, and when choosing a mounting po-
sition it is therefore advisable to look for a position with relatively
high flow / turbulence.
For new installations it is recommended to clean and calibrate
the sensor one time per week to ensure stable operations. When
more experience has been gained on the actual fouling rate at the
installation site, this maintenance frequency may be changed.
CLEANING
The SulfiLogger™ sensor’s durable design makes cleaning easy.
•
Remove any accumulated rags/fibers and larger debris from
the sensor.
•
Wipe off the sensor head with a cloth. Take special care to
ensure that the inlet slit(s) at the front of the sensor head is
completely clean.
•
If needed use water or a mild soap to clean the sensor head.
This is especially important if a greasy layer has build up
on the sensor or if a layer of biofilm can be directly seen.
Ethanol can also be used.
CALIBRATION
The SulfiLogger
™
sensor comes factory calibrated and is as such
ready to use immediately as received. However, calibration in
7

output August 19, 2019 8:28 Page 8
the field can be a good way to ensure that the sensor keeps the
absolute accuracy after prolonged deployment. Initially it is rec-
ommended to calibrate the sensor before installation and sub-
sequently once every month, but this can be subject to specific
installation conditions.
The calibration procedure is simple and has no demand for access
to SCADA values or connection of computer/laptop or other data
viewing devices. The calibration routine relies on the SulfiLogger
™
sensor’s internal detection capability of the calibration gas and
on the presence of a magnetic switch which is activated by the
calibration cap. A number of different indicator light modes gives
signal to the operator of what to do during the calibration, as
described below. The position of the indicator light is shown in
Figure 1.
Figure 1: Close-up view of the SulfiLogger
™
sensor showing the
position of the LED indicator light used for signaling during the
calibration process (see below).
To calibrate the SulfiLogger
™
sensor, a calibration gas with a con-
centration of 1000 ppm
H2S
is needed. This can be ordered sepa-
rately from Unisense together with a calibration kit that facilitates
the activation of the calibration mode in the sensor and ensures a
relevant flow of gas to the sensor during calibration. Refer to the
8

output August 19, 2019 8:28 Page 9
table on page 13 for more details on the ordering of calibration
equipment. Figure 2 shows how the calibration kit and gas bottle
is mounted on the SulfiLogger
™
sensor. The reduction valve on
the gas bottle ensures that the correct flow of gas is exposed to
the sensor, and the valve should therefore be opened fully when a
calibration is ongoing.

Overview of light indications on the SulfiLogger™ sensor
The indicator light on the SulfiLogger
™
sensor is constantly giving
a status of the sensor and can as such be used to check that the
sensor is on. Before calibration is initiated it is important to be
familiarized with the various status signals that the sensor uses as
indications and calls for operator actions. These are summarized
in the table below.
The calibration procedure of the SulfiLogger
™
sensor consists of
the following steps:
1.
Initially, check that the sensor is on and is in normal opera-
tion mode showing Green flashes on the indicator light with
one flash every 4 seconds. (slow blinking)
9

output August 19, 2019 8:28 Page 10
Light indication Explanation
Green, 1 per 4 sec Sensor is operating normally
Green, 1 per sec Calibration cap mounted
Green, 3 per sec Gas signal detected
Green and red, 1 per sec Minimum calibration
Green and red, 2 per sec Full calibration. Close and take off cap
Green, 15 times Calibration succeeded
Red, 15 times Calibration failed
2.
Connect the gas bottle to the calibration cap with the sup-
plied flow regulator and gas tube
3.
Mount the calibration cap on the sensor and make sure to
align the arrow of the calibration cap with the position of
the indicator light (this activates the magnetic switch in the
sensor). Thereby the calibration mode in the sensor is acti-
vated and the light indicator now switches to green flashes
with one flash every second (medium blinking)
4.
Open the flow regulator on the gas bottle to allow H
2
S gas
to reach the sensor. After a short time the light indicator
should switch to green flashes at 3 flashes every second
(fast blinking)
5.
After approximately 3 minutes a minimum calibration has
been achieved and the calibration procedure can be termi-
nated. This is indicated by an alternating green and red light
signal with one flash every second. If time allows we recom-
mend to continue the calibration until a full calibration has
been completed (see below)
6.
A few minutes after the minimum calibration the flashing
rate switches to faster alternations between red and green
light at 2 flashes per second. This indicates that a full cali-
10

output August 19, 2019 8:28 Page 11
bration has been completed and it is time to terminate the
calibration procedure
7.
When either a minimum or a full calibration has been com-
pleted the regulator valve is closed on the gas bottle and the
calibration cap should be removed. Pay close attention to
the indicator light when removing the calibration cap since
the result of the calibration is immediately shown on the
indicator light when the magnetic switch is turned off. The
indicator light shows 15 fast flashes (5 per second) of either
green light or red light. If the flashes are green, the cali-
bration has been completed and stored successfully. It the
flashes are red, the calibration has failed during the process
and the calibration procedure must be restarted.
!CAUTION
If your sensor is installed using a flow cell, you must inspect
the O-ring at the tip of the sensor when it is removed from
the flow cell. If O-ring is worn or damaged it must be replaced
by a new. Replacement O-rings and O-ring grease have been
delivered together with the flow cell.
IMPORTANT NOTE
The fifteen short green flashes at the final stage of calibration
is the only indication visible to the operator of a successful
calibration. However, if in doubt, we recommend that the
calibration validity is checked subsequent to calibration by
exposing the SulfiLogger
™
sensor to the calibration gas and
checking the reading at the SCADA system or through the
SulfiLogger App (The SulfiLogger
™
sensor only). Please make
sure to turn the calibration cap so that the arrow is NOT
11

output August 19, 2019 8:28 Page 12
aligned with the light indication signal when checking the
calibration in order to avoid that a new calibration procedure
is initiated.
