Level

Level

Level measurement covers continuous level, interface, and density measurement as well as point level detection for liquids, pastes, bulk solids, and liquefied gases—most often in tanks, silos, and movable containers. Endress+Hauser’s portfolio spans a broad range of principles, including radar, vibronic point level, guided radar, ultrasonic, capacitance, hydrostatic, conductive, float switch, radiometric, paddle switch, servo, electromechanical, and microwave barrier technologies. 

Reliable level information supports constant product quality, safety, and economic efficiency. It reduces the likelihood of overfill and dry-run events, stabilizes residence time in vessels, and improves inventory accuracy for planning and logistics. For solids handling, dependable point-level and continuous-level measurement helps prevent blockages, enables controlled filling and discharge, and supports safer operation where dust, abrasion, and variable bulk density can challenge instrumentation.

Technology selection is driven by process constraints and required measurement behavior. Non-contact radar often fits demanding vapor, pressure, and temperature conditions; guided wave radar supports interface duties and narrow geometries; ultrasonic can be effective where acoustic paths are stable; vibronic devices provide strong point level performance across many fluids; capacitance and conductive methods address specific media and interfaces; hydrostatic measurement suits applications where pressure head is representative; and radiometric approaches are reserved for extreme process conditions where other principles are impractical.

Common applications include tank farms, reactor and blend vessels, surge tanks, and storage in chemical and life-science production, as well as sanitary vessels in food and beverage. In water and wastewater, level and sludge blanket measurement supports basins, lift stations, clarifiers, and chemical storage. In bulk solids, continuous-level and point-level devices are applied in silos for powders, pellets, cement, grain, and mined materials, where dust, buildup, and abrasion must be addressed in mechanical design and mounting. 

A well-designed level measuring point extends beyond the sensor to include mounting, configuration, diagnostics, and maintainability. Planning considerations include nozzle geometry, turbulence, foam, buildup, and required proof testing. Commissioning benefits from standardized device behavior and digital communications where applicable, while ongoing maintenance is improved through clear status indication and consistent documentation. Endress+Hauser positions support across the measuring point life cycle, from planning through commissioning and maintenance.
