Calibration for Electromagnetic Flow Meter Transmitter Settings

Before an electromagnetic flow meter is delivered, the transmitter needs to be configured according to the application and sensor specifications.

The calibration process is therefore not only about checking the measured flow. It also involves verifying that the transmitter settings correctly correspond to the sensor and the customer's application requirements.

Matching the Transmitter with the Sensor

The transmitter is configured according to the corresponding electromagnetic flow sensor.

Key parameters may include:

• Sensor diameter
• Flow meter measuring range
• Flow direction
• Electrode configuration
• Liner information
• Flow unit
• Totalizer unit
• Output configuration

Correct parameter matching ensures that the transmitter can properly process the signal received from the sensor.

Setting the Measuring Range

The required flow range is entered into the transmitter according to the technical specification.

For example, the engineer may configure:

Flow Unit: m³/h
Measuring Range: Customer specified
Display: Instantaneous Flow + Total Flow
Output: 4–20 mA / Pulse / RS485

The actual configuration depends on the customer's project requirements.
