The piezo disc is glued directly onto the bottom side of the IBC. For a good functioning of the measuring method a high quality of the bonding is crucial to ensure, on one hand a good measurement and on the other hand a long stability and durability of the bonding. A possible placement of the Sense MCE IBC is on the top side of the IBC, via suitable adhesive materials. The Sense MCE IBC and the piezo sensor are connected with a cable of suitable length. The cable is shielded coaxial to reduce potential electromagnetic interferences. Figure 7: Principle of installation of Sense MCE IBC and connected piezo disc on IBC. Page 26 of 46 Release Rev. D, 2020-12-15 MYNXG Product GmbH, 2020. All rights reserved SENSE MCE IBC Operating Instruction CAU T I ON Ensure that all instructions of the adhesive materials are followed. Special care should be taken care regarding the temperature during application and the time needed until full cure. All steps necessary for the installation are described further below 1. Prepare Bottom Side:

a. Identify the area (square, size around 60x60 mm) on the bottom side, where the piezo sensor shall be attached. For the area it is important to ensure that it is completely horizontal when the IBC is stored in a horizontal position, otherwise the TOF measurement will not work properly b. Do a first cleaning of this area with a lint-free cloth soaked with alcohol

(isopropanol). 2. Mount Piezo Sensor:

lint-free cloth. a. The pre-assembled piezo should be cleaned with alcohol (isopropanol) using a b. Glue should be applied on the piezo disc, using provided glue pack c. The piezo assembly should be pressed on the IBC surface, by making sure that the piezo disc itself is located in the specified area d. Hold the pressure for 30 seconds e. The bonding reaches stability after 5 min, final strength of the bonding is reached after 24 hours. 3. Mount Sense MCE IBC a. The surface of the IBC, where the box shall be located, should be clean and dry before applying the provided glue b. Guide the cable from the piezo towards the specific area c. Attach at least five self-adhesive tie sockets to the side of the IBC in equal distances. d. Use cable ties to attach the cable at the self-adhesive tie sockets. e. Apply the bonding material f. Press the mounting plate on the surface of the IBC g. Press for 10 seconds with firm pressure. h. Click the sensor box on the mounting plate, by making sure that all notches are inserted on the housing. Rev. D, 2020-12-15 MYNXG Product GmbH, 2020.
