Engineering Selection Guide
Level measurement is a vessel-and-medium problem before it is a sensor problem. The same vessel may need continuous inventory, a high alarm, a low pump-protection point or an interface between two liquids. Those tasks can justify different instruments even when they share a nozzle. Begin by defining what the measured level means, the required response and the consequences of a missed or false indication. Then record vessel height, measuring span, nozzle dimensions, internal structures, agitation and the accessible mounting positions.
Liquid and bulk-solid behaviour narrows the available principles. Hydrostatic measurement responds to liquid head and therefore depends on density. Float and displacer devices interact mechanically with the medium. Capacitance and guided-wave methods depend on probe condition and electrical properties. Free-space radar follows an echo path that can be affected by the nozzle, beam obstructions, weak reflections or buildup. Solids add dust, repose angle, abrasion, bridging and impact loads. Foam, vapour, condensation and coating should be described as operating conditions, not treated as minor afterthoughts.
A selection review also needs the full process envelope: pressure, temperature, vacuum, filling and emptying rates, cleaning cycles, hazardous-area classification and the material compatibility of every wetted part. For an open tank, atmosphere may be the reference; for a closed pressurised vessel, vapour pressure may need compensation or a principle that does not respond to it. When level is converted to volume, tank geometry and strapping data are a separate calculation and should not be confused with the sensor's distance or level reading.
The products below cover continuous transmitters and point switches, but a category page cannot prove that every option suits every vessel. Provide a sketch or drawing where possible, including nozzle, internals and expected low and high levels. Ask for the selected SKU's process limits, blind or dead zones, connection, materials, output, environmental protection and relevant certificate. If a performance value or approval is not published for that code, keep it as an open engineering item until written evidence is supplied.

Engineering Selection Guide
A dimensioned sketch showing vessel height, nozzle size and length, intended mounting point, expected low and high levels, agitators, coils, ladders and filling streams is highly useful. Add pressure, temperature and cleaning conditions. For non-contact measurement, identify anything within the possible beam path. For probe instruments, state the available insertion path and mechanical loads. The proposed device can then be reviewed against a real geometry.
Changing density directly changes the relationship between liquid head and level in hydrostatic measurement. Foam may create an interface that some principles detect differently, may weaken a reflected signal or may cause coating on a probe. The effect depends on the principle and severity, so describe foam thickness, persistence and process phase. A supplier should explain the proposed principle and any commissioning test rather than promise a universal correction.
A transmitter may provide a programmable output or alarm, but that does not automatically make it an independent or certified overfill protection layer. The process risk assessment determines whether a separate switch, independent connection, test procedure or specific certification is required. Treat measurement, basic control and protective functions as distinct requirements, then verify the selected hardware and documentation for each claimed role.
