Commissioning IFL 70x IQ 3.3.2 General installation conditions Minimum distance from basin wall = 0.2 m + 0.05 * (water depth - immersion depth in m) Immersion depth (= 0.1 m) Wall Immersion depth Dead zone (= 0.4 m) Depth of the sludge level Water depth Measurement cone approx. 7° (half-value angle) Sludge level free of fixtures and obstacles Vertical installation Height of the sludge level Bottom of the basin Fig.
IFL 70x IQ Commissioning Sensor installation The following conditions should always be met: Vertical Sufficient distance from the basin wall (minimum distance, see formula in Fig. 3-1). If the distance to the wall of the basin is small, the wall should be rather smooth. Immersion depth (0.05 m ... 3 m) Minimum distance between the sensor bottom and sludge blanket = 0.4 m ("dead zone").
Commissioning IFL 70x IQ 3.3.5 Short-term interferences due to obstacles Certain events may for a short period of time affect or interrupt the measurement. In waste water treatment plants, these events are normally: Moving scrapers that displace an installed sensor from its measuring position or cross its measuring cone. Fixtures permanently installed in the basin such as pipes or scrapers that are touched by the measuring cone of a sensor on a scraper bridge when rotating.
IFL 70x IQ Commissioning 2 Plug the socket of the SACIQ (SW) sensor connection cable onto the plug head connector of the sensor. At the same time, rotate the socket so that the pin in the plug head connector (1) clicks into one of the two holes in the socket. 3 Then screw the coupling ring (2) of the sensor connection cable onto the sensor up to the stop. NOTE (only IFL 700 IQ) If the sensor is connected to the IQ SENSOR NET, the mechanical wiper may start moving unexpectedly.
Commissioning IFL 70x IQ 3.4 Initial commissioning Prerequisite for the display of measured values of the IFL 70x IQ on a terminal of the IQ SENSOR NET system is the current software version of the controller and the terminal. The current software is available on the Internet under www.YSI.com. 1 Install the sensor at the measuring location and establish the connection to the IQ SENSOR NET. (see section 3.3). 2 Using <>, select the IFL 70x IQ sensor in the measured value display.

Then navigate to the setting menu (setting table) of the sensor. The exact procedure is given in the relevant IQ SENSOR NET system operating manual.
Commissioning Setting IFL 70x IQ Selection/values Explanation The rising side of the echo is evaluated for the measured value determination. One of two methods can be selected for this. Method Rel. threshold The measured value is equivalent to the point where the intensity of the echo reaches the adjusted relative threshold.
IFL 70x IQ Commissioning Setting Selection/values Explanation With this setting, the echo to be evaluated is determined. The echo is automatically identified according to the criterion that was set. Echo selection Topmost echo The topmost echo (from the surface of the water) is used for calculating the measured value. To ensure that a weak echo can be identified among the surrounding echoes, the interfering echoes can be suppressed with the setting, Minimum intensity.
Commissioning IFL 70x IQ Setting Selection/values Explanation Establishing time 0 ... 120 ... 600 sec Filter that ignores (interfering) echoes whose residence time within the ultrasonic cone is shorter than the time defined here. Example: To ignore a scraper, the maximum duration of its visibility in the ultrasonic cone has to be entered. Temperature 3 - 12 0.0 ... 15.0 ... 50.0 The temperature affects the speed of sound in the measuring medium.

IFL 70x IQ Measuring 4 Factors affecting the measured value Measuring 1 Submerse the sensor in the sample. 2 Read the measured value on the terminal of the IQ SENSOR NET system. The following factors have an impact on the measured value: The environmental conditions at the measuring location deviate too much from the sensor settings (Immersion depth, Water depth, Temperature) The distance between the ultrasonic transducer and the sludge level is too small (dead zone, see also section 3.3.

IFL 70x IQ Maintenance, cleaning, accessories 5 Maintenance, cleaning, accessories 5.1 General information WARNING Contact with the sample can be dangerous for the user! Depending on the type of sample, suitable protective measures must be taken (protective clothing, protective goggles, etc.). We recommend to clean the shaft and ultrasonic transducer surface of the sensor if the sensor has been in the measuring solution without operating for a lengthy period of time. 5.
Maintenance, cleaning, accessories IFL 70x IQ We do not recommend unscrewing the sensor from the sensor connection cable when cleaning the sensor shaft and measuring windows. Otherwise, moisture and/or dirt can get into the plug connection where it can cause contact problems.
IFL 70x IQ Maintenance, cleaning, accessories Cleaning 1 Switch on the maintenance condition for the sensor. 2 Pull the sensor out of the sample. 3 Get rid of any coarse impurities on the sensor (brush it off in a bucket of tap water, wash it down with a hose or wash it off with a cloth). NOTE Carefully clean the wiper of the IFL 700 IQ from outside. 4 Clean the sensor shaft and the surface of the ultrasonic transducer as explained in the point CLEANING AGENTS, page 1.

IFL 70x IQ What to do if... 6 What to do if... Mechanical damage to the sensor Cause Display "----" (no valid measured value) Cause Remedy Sensor is permanently in the air Immerse the sensor in water (see section 3.3.2) There are too many air bubbles in the water or on the ultrasonic transducer Select a measurement location free of air bubbles Sensor is dirty – Clean the sensor and/or its environment Remedy – Return the sensor – Check the function of the wiper (see section 3.
What to do if... The measured value is not within the expected range IFL 70x IQ Cause Remedy The Water depth is not set correctly Set the Water depth and Immersion depth correctly (e.g., the bottom echo or multiple echoes between the bottom of the basin and the surface of the water are interpreted as measured value echoes.
IFL 70x IQ What to do if... Number and position of the echoes changing often Cause Remedy Small temporary interfering echoes – Check Echo selection (Topmost echo or Strongest echo) (e.g. sludge flakes sinking slowly) – A higher value for the Minimum intensity filter ignores echoes from small, slowly sinking sludge fields. New sludge blankets developing – Check Echo selection (Topmost echo or Strongest echo) (e.g. a new sludge blanket developing on top of an old, concentrated sludge blanket).
