Level measurement

88 Continuous level measurement in liquids

4. Instrument selection within the measuring principle

Hydrostatics (pressure / differential pressure)

Required application data • Pressure and temperature • Medium density • Required material compatibility • Process connection

• Measuring range • Required accuracy • Ambient conditions (temperature change, moisture, …)

Application limits for hydrostatic level measurement • Temperature up to –70°C/–94°F or

•

Advantages • Unaffected by surface foam • Unaffected by tank obstacles/tank geometries • Simple engineering • Established technology • Remote access via Bluetooth® • Heartbeat Technology
