Abstract: An electromagnetic flowmeter for measuring a flow rate in lines for conveying and distributing electrically conducting liquids, comprising a flowmeter body forming a substantially cylindrical open ended chamber, delimited by side walls of electrically insulating material. The flowmeter body accommodates a pair of facing electrodes arranged at diametrically opposite regions of said chamber and a magnetic field generator generating induction lines orientated at right angles to a line connecting the electrodes and to the chamber axis. The electrodes can be connected to a measuring device for measuring the potential difference induced between the electrodes by the fluid flow in the presence of said magnetic field. Two sleeves on the flowmeter body provide an extension of the chamber ends. The sleeves are flexible and fit hermetically over two duct portions along which the flow-rate is to be measured.
