Electronet series ELMAG - 100S are microcontroller based two / four wire insertion type electromagnetic flow meters which measure the flow rate in a completely filled pipe by monitoring the voltage produced when the (conductive) liquid moves through a magnetic field. The meter is available in non-corrosive material which provides long term reliability with less maintenance cost. This simple to install magmeter delivers accurate flow measurement over a wide range of pipeline sizes ranging from DN80 to DN300. Output options include a Digital / Frequency signal, 4 to 20 mA & RS485.
