  1. 1. Evaluating sensor accuracy and repeatability in gasketed plate heat exchangers

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Nils Engman; [2023]
    Keywords : Sensors; IoT; Heat Exchangers; Technology and Engineering;

    Abstract : Alfa Laval has connected sensors to their gasketed plate heat exchangers (gphe) to extend their customer service offering. To develop this service further the flow through the GPHE is needed. In this thesis, the objective was to evaluate an inexpensive flow switch and two sensor kits that measure pressure and temperature. READ MORE

  3. 2. Benchmarking a 1 kW hybrid hydrogen fuel cell system

    University essay from Lunds universitet/Institutionen för energivetenskaper
