  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. A study on gas-module test-system to attain high precision gas-flow control in medical ventilators

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Vishnu Narayanan; [2021]
    Keywords : Gas-flow control; calibration of gas flow controller; trimming of gas-module; flow measurement; Gasflödesreglering; kalibrering av gasflödesregulatorn; trimning av gasmodul; flödesmätning;

    Abstract : A medical ventilator is a life-sustaining device that helps critically ill patients with complete or partial breathing support. It provides a patient with the right amount of air and/or oxygen as per requirement. It is therefore essential to have a highly accurate device controlling the flow of these essential gases.

  4. 3. Pressurizing of high-pressure fuel system forsingle cylinder test cell

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Gustaf Glaad; [2019]
    Keywords : Alternative fuels; Ultra high-pressure fuel system; Common rail direct injection fuel system; Diesel-like fuels; Compression ignited fuels;

    Abstract : This master thesis covers the development of a high-pressure fuel system for compression ignitedfuels such as diesel and diesel-like fuels that will be deployed into a single cylinder test cell at AVLMTC Södertälje, Sweden. The test cell is used by AVL to conduct research and testing of new fuelsfor their customers and this new fuel system will widen the span of fuels able to be tested by theequipment. READ MORE

  5. 4. Non-Invasive Liquid Metering Method Analysis

    University essay from KTH/Mekatronik

    Author : Gustav Sten; Thibault Helle; [2018]
    Keywords : ultrasonic; liquid; metering; non-invasive; ultraljud; flöde; vätska; icke-invasiv;

    Abstract : The ability to measure flow in pipes often introduces expensive and difficult installations due to existing flow-meters being invasive. To solve this a non-invasive solution has been found by testing and evaluating different mechanical and electrical methods using ultrasonic piezo-crystals and time-of-flight calculations. READ MORE

  6. 5. Rostfärgat slam i dränagesystem vid vattenkraftsanläggningar : orsaker och åtgärder

    University essay from SLU/Dept. of Energy and Technology

    Author : Anders Hamrén; [2013]
    Keywords : vattenkraft; dammar; järnbakterier; flödesmätning; dränagesystem;

    Abstract : From embankment dams is something that has long been noticed and given rise to different questions. The most serious question is if the sludge is a result of inner erosion through the dam, and thus consists of material transported from the dam. READ MORE
