  • Page 10 (PPE) and the correct use of gases and/or chemicals, and to carefully read all relevant Safety Data Sheets. Installation and calibration of the SulfiLogger™ sensor may include the risk of contact with hazardous gases or liquids. It is especially important regarding the SulfiLogger™ sensor for hydrogen sulfide. Hydrogen sulfide is a highly toxic gas and special precautions are needed to avoid the risk of injury or death.

    OVERVIEW The SulfiLogger™ sensor is available in a number of different con- figurations. Some of these are available in ATEX certified versions. Please pay close attention to your product type during the reading of this manual and the installation of the sensor. ATEX certified versions of the sensor are labeled SulfiLogger™...

  • Page 13: Maintenance

    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.
  • Page 14 1000 ppm 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...
  • Page 15 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.

  • Page 17 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.
  • Page 18 aligned with the light indication signal when checking the calibration in order to avoid that a new calibration procedure is initiated.

    SULFILOGGER™ SENSOR SEWER INSTALLATIONS - TIPS AND TRICKS When installing the SulfiLogger™ sensor for monitoring hydro- gen sulfide in sewer networks the following notes may serve as guidelines for a monitoring campaign: • Hydrogen Sulfide (H S) is created under oxygen free con- ditions in the sewer which typically occurs in Force Mains (pumped sewer lines).
  • Page 27 be done by attaching the sensors threaded fitting to the pressure pipe or through a dedicated load-lock system at the chosen position on the pipe. Note however, that liquid velocities are often high in pressurized pipes, and hence there is an increased risk of sensor damage associated with this type of measurements.

  • Page 28: Troubleshooting

    TROUBLESHOOTING Problem: The SulfiLogger App does not recognize the SulfiLog- ger™ sensor when it is connected (version 1010 only). Solution: Try charging the battery of the PowerCom Box, or try disconnecting the wire from the PowerCom Box to the sensor and reconnect it subsequently.
