Electromagnetic flow meters are based on the induction principle. Learn more about the design and functionality of flow sensors.

To ensure high measurement accuracy, some aspects, such as grounding, must be taken into account when installing and mounting flow meters. See the know-how section to find out in detail what needs to be observed.

Prior to delivery, all electromagnetic flow sensors are calibrated by an accredited calibration laboratory according to ISO 17036 (ACCREDIA certificate LAT237) and do not require calibration on location. You will receive the calibration certificate on paper and electronically upon delivery of the product.

The flow sensor is configured via the Baumer Control Panel (BCP) operating and control software. The software allows user-friendly and easy access to all programmable functions of the flow meter. A mini USB cable is required for connecting the device to a PC. The following section contains information on what to observe prior to the configuration and how the software is structured.

The CombiSeries with display provides operation and process monitoring that is standardized throughout the entire CombiSeries line of sensors for temperature, pressure, conductivity, flow and level measurement. All required information can be seen at a single glance, even from a long distance. The display allows intuitive operation with a touch screen and two relay outputs for direct process control.

From drinking water to chemicals – the electromagnetic flow meters from Baumer offer a wide range of measuring tube linings (liner) for every medium. The correct choice of the ideal material depends on the medium, proportion of solids in the medium and process temperature. 

Resources are saved through the precise measurement of reporting, mixing, and dosing processes since they can be optimized and controlled with high precision. This reduces media waste to a minimum. Customized coreless air coils that cover the entire length of the measuring tube ensure a lasting, temperature-resistant magnetic field that achieves stable and reliable measurement results with an accuracy of up to 0.2%. 

The electromagnetic flow meters PF75 are highly precise and equipped with a continuous measuring tube without constriction or fittings, which prevents pressure loss in the system. This allows optimal pump performance without energy loss in the system. The special magnetic coil design results in high precision without having to reduce the measuring tube diameter to increase the flow velocity.
