Features ・Electromagnetic flowsensor without moving parts suitable for use in machines. ・With absence of moving parts, there is less failure due to its contaminants. ・Low pressure loss ・No straight pipe required, compact design, and easy to install. Measurement Principle By applying the Faraday’s law of induction, with a current flowing through the coil to generate a magnetic field in the flow path, an electromotive force is generated when a conductive liquid passes through the flow path. Electromagnetic force becomes signal which is proportional to flow velocity, and this voltage is measured to convert it to flow rate. The flow rate is calculated by multiplying this flow rate by the cross-sectional area of the flow path.
