Bilek, S. Sosnowski // Econtechmod : scientific journal. — Lviv : Lublin, 2018. — Vol 7. — No 4. — P. 9–12.https://ena.lpnu.ua/handle/ntb/46286The work presents a simple electronic device that helps to monitor the basic parameters of the reverse osmosis (RO) system during the concentration of birch tree sap. The construction costs are low (around 150 Euro) but the functionality of the device is high. It has an in-build two channel conductometer and can measure the volumetric flow rate of two streams of liquids. The collected data are transmitted wirelessly via Bluetooth to a PC computer. The new data acquisition system can help to monitor the work of RO apparatus in standard conditions or in the research and development works. It provides essential data for the process modeling and economic aspects analysis of birch sap concentrate production.9-12endata acquisitionmicrocontrollersbirch tree sapreversed osmosisnew technologiesArticle© Copyright by Lviv Polytechnic National University 2018© Copyright by Polish Academy of Sciences 2018© Copyright by University of Engineering and Economics in Rzeszów 2018© Copyright by University of Life Sciences in Lublin 20184Wawer J.
