Build-up Identification of build-up on the sensor surface

How it works Flow: Magmeter (Promag)

• The build-up index is based on the difference in electrical conductivity between the fluid and the build-up • The distribution of electrical conductivity within the measuring tube is analyzed to compute an indexed value that changes proportionally when the build-up increases • The baseline of 0% is set during factory calibration of a new device without build-up and ranges to 100%, which represents the maximum detectable build-up formation

Impact on device/process/operations • Reduced reliability and measuring performance • Flow could be restricted if no actions are taken • Potential negative impact on further process components Benefits of Heartbeat Technology • Increased reliability and process safety by early detection of build-up • Allows you to monitor the formation of build-up and consequently plan maintenance actions accordingly, e.g., cleaning Flow measurement: • Build-up index – Magmeter (Promag) • Oscillation damping – Coriolis (Promass) • Signal strength – Ultrasonic (Prosonic Flow) Level measurement: • Fork frequency – Point level (Liquiphant) • Area of incoupling – Free space radar (Micropilot) • Relative echo amplitude – Guided radar (Levelflex) Pressure measurement: Signal noise and signal median (Cerabar and Deltabar) Heartbeat Technology parameters

Pressure: Deltabar • The signal noise is monitored during operation • In the case of a plugged impulse line (e.g., due to build-up), the signal noise will be affected • If the defined threshold is exceeded, the device will create a diagnostic event (maintenance required)
