Page 5: Device Description
2 Device description The FMG90 series from Omega, is a non-contact flow sensor. The measurement is performed using magnetic induction and works without any moving parts. The FMG90 is used for measuring or metering water and aqueous solutions. The compact design and independence from the intake and discharge sections allows the FMG90 to be used under a variety of conditions. -
Page 6: Intended Use
Intended use The magnetic inductive flow sensor FMG90 must only be used for measuring and metering liquids with a minimum conductivity of 20 μS/cm. WARNING! No safety component! The magnetic inductive flow sensor of the series FMG90 are not safety components in accordance with Directive 2006-42-EC (Machine Directive). -

Page 8: Construction And Function
Construction and function Construction: The measuring tube with its earthing sleeves and electrodes passes through the sensor housing and forms the external process connection of the FMG90. A magnetic field for the measurement process is generated inside the sensor housing, which also contains the sensor and signal conditioning circuitry. -
Page 9: Installation Instructions
Installation instructions CAUTION! Risk of malfunction due to external magnetic fields! Magnetic fields close to the device can cause malfunctions and should be avoided. Ensure that no external magnetic fields are present at the installation site of the FMG90. • The FMG90 can always be installed anywhere along the pipeline. -
Page 10: Assembly
• If two or more FMG90 devices are used side by side, maintain a separation of at least 2.5 cm between adjacent devices. If adjacent devices are too close together, operation of both devices may be impaired due to mutual interference. 5.2 Assembly The FMG90 is installed directly into the pipeline. -
Page 11: Electrical Connection
6 Electrical connection The electrical connection of the FMG90 is via the 4-pin plug M12x1 at the top. The corresponding connection cables with moulded coupling socket are available in various lengths. CAUTION! Electric current! The electrical connection should only be carried out by a fully qualified electrician. De-energize the electrical system before connecting the FMG90. -
