Electromagnetic Flow Meters

Electromagnetic flow meters (or ‘magmeters’) are a popular and highly accurate flow measurement option for wastewater applications that require a low maintenance solution without pressure drop.

As covered in BS/ISO 6817, electromagnetic flow meters operate on the principle of Faraday’s Law, which states that the voltage induced across any conductor as it moves at right angles through a magnetic field is proportional to the velocity of that conductor.

Closed conduit flow measurement

SIRIS MCERTS-certified electromagnetic flow meters are designed for measuring liquid flow within an enclosed pipe.

Electromagnetic flow meters provide an unobstructed flow path which avoids pressure loss and they are unaffected by issues such as temperature or viscosity.

All SIRIS electromagnetic flow meters satisfy regulatory requirements.


Low maintenance solution

Electromagnetic flow meters are often labelled a “fit and forget” solution due to their low maintenance requirements, though correct and MCERTS qualified installation is essential for their correct working. While we do recommend occasional servicing to ensure it is working to optimum standards, the lack of moving parts makes this type of flow meter a robust and easy-to-maintain option.

Accurate & reliable data

SIRIS flow meters carry MCERTS accreditation so you can be confident that the data provided is reliable and accurate and will provide accurate and reliable long-term flow measurement.

Our flow meters are designed to meet with relevant regulatory discharge and MCERTS requirements.

All SIRIS products are compatible with our web-based data recording software, which allows quick and easy access to your data at any time – from any location.
