Measuring distances up to 100 m / 328 ft.
Different antenna options, e.g. for corrosive or abrasive media, high pressure or temperature and applications with agitators.
Also suitable for hazardous areas, Functional Safety (SIL) or hygienic applications.

Guided Radar (TDR)

Contact level measurement of liquids, solids or liquid-liquid interfaces (Ɛr ≥1.3).
Measuring distances up to 60 m / 196 ft.
Large choice of probes, e.g. for aggressive or abrasive media, high pressure or temperature and tanks with internals or boiling product surfaces.
Suitable for hazardous areas, Functional Safety (SIL) or hygienic applications.

Ultrasonic

Non-contact level measurement of liquids, bulk and solids.
Measuring distances from 0.25…15 m / 0.82…49 ft.
Resistant materials for transducers and process connections, e.g. for slightly corrosive media.
Also suitable for hazardous applications.

Potentiometric

Contact level measurement of liquids and pastes (>50 μS/cm).
From 0.2…3 m / 1…9.8 ft probe length.
Not sensitive to build-up and foam.
Also suitable for hygienic applications with tough, pasty or highly adhesive media with low conductivity.

Displacer

Contact level measurement of liquids and liquid-liquid interfaces in tanks or bypass chambers.
Measuring distances up to 5.5 m / 18 ft (longer on request).
For a broad range of process conditions, e.g. pressurized or high temperature vessels, corrosive media etc.
Suitable for hazardous areas.

Pressure

Contact level measurement of liquids and liquid-liquid interfaces.
Large choice of hydrostatic pressure level transmitters.
From ultra-compact versions to diaphragm sealed gauges.
Suitable for aggressive, abrasive or HT media, hygienic requirements or hazardous areas.

Level Switches

Vibration

Point level detection of liquids and solids.
Insertion lengths up to 6 m / 19 ft (liquids) or 80 m / 262 ft (solids).
Insensitive to changes of media properties, e.g. density, dielectric constant (εr) or electrical conductivity.
For high/low level detection, dry-run and overfill prevention even in highly critical applications (SIL) or hygienic environments.

Capacitance

Point level detection of liquids, liquid-liquid interface and solids (Ɛr ≥1.5)
Compact housing with very short insertion length of 15 mm / 0.59″.
For standard and advanced hygienic applications in tanks or pipelines.
Detects foam or even a change in media characteristics, e.g. the degree of water contamination.
