DUTY & SELECTION
Where to consider this type
An electromagnetic meter, often called a mag meter or EMF meter, measures flow using the electrical signal induced when a conductive liquid moves through a magnetic field.
Installation and commissioning
Before the meter is selected
- Lowest measured conductivity
- Liner, electrode and seal compatibility
- Full measuring tube, grounding and pipe profile
- Integral/remote configuration, accuracy basis and simultaneous powered outputs
Before the system is handed over
- Confirm the installation drawing, orientation and access for service.
- Match the actual flow range and permitted pressure loss to the project.
- Record meter serial number, start reading and any output scaling.
- Commission communications against the receiving system and retain the test record.
Reading and communication
Documentation mentions: Pulse output, 4–20 mA, RS485. These may be optional or specific to a variant.
Discovery tags come from the documented description, including optional capabilities. Confirm inclusion and exact size/configuration.
A connected metering system is five parts: meter → interface or module → network or gateway → software → billing, dashboard or control system. A quotation should name who supplies and maintains each one. AMR-ready equipment may still require separately quoted radio, gateway, head-end and billing software.
