The float switch cost-effective solution for point level detection in appropriate fluids. It is used in tanks and vessels as a pump protector or level alarm in open basins, like in sewerage treatment plants. The float switch has two output options, a NAMUR switching signal or a change-over contact. Check out the Liquifloat device for point level applications.

Benefits :

• Reliable and cost-effective point level detection in liquids
• Electrical connections to NAMUR for hazardous areas (to Zone 1) or change-over contact (AC/DC) for universal standard application

Radar level measurement with top-down installation of a Micropilot sensor offers perfect application fit in all industries. Non-contact radar with simple commissioning, trouble-free operation saves time and money. For usage in a wide range of applications - be it in simple storage tanks, in corrosive or aggressive media or high accuracy tank gauging applications.
Radar level measurement is a safe solution even under extreme process conditions (pressure, temperature) and vapors. Micropilot can also be used in hygienic applications for non-contact level measurement. Micropilot versions are available for different industries like for water/wastewater, the food industry, life sciences or the process industry. Various antenna versions for every kind of radar applications are available.

Benefits :

• Non-contact, maintenance-free measurement
• Unaffected by medium properties like density and conductivity, in bulk solids also unaffected by filling noise and dust
• Freely adjustable measuring range
• For high temperatures up to +450C/+842F

Guided radar level measurement with top-down installation of a Level flex sensor offers perfect application fit in all industries. Guided radar with simple commissioning, trouble-free operation saves time and money. For usage in a wide range of applications - be it in simple storage tanks, in corrosive or aggressive media or heavy duty applications.
Guided radar level measurement is well suited to liquids and bulk solids. The surface condition of the medium is of minor importance due to the safe guidance of the reflected waves. Turbulent liquid surfaces or foam formation as well as different angled surfaces or outflow funnels, as the occur in bulk solids, do not influence the measurement. Guided radar is also the first choice for interface measurement.

Benefits :

• Reliable measurement : Unaffected by medium surfaces and tank obstacles or baffles
• Additional measuring safety through End-of-Probe (EoP) evaluation
• Safe measurement also during filling

Capacitance level measurement with Liquicap is a simple and cost-effective solution which offers a wealth of possibilities for level monitoring in liquids. Particularly in small tanks and build-up forming media. Point level detection works with Liquicap, Liquipoint, Minicap or Solicap capacitance level switches also in applications involving aggressive media and heavy build-up in liquids and solids.

Benefits :

• Proven and tested measuring principle - robust and safe
• Universally adaptable probe
• Reliable operation also in strong build-up formation and viscous media
• Easy commissioning

Be it water or any other liquid, hydrostatic level sensors measure in various applications in different industries, like food, water/wastewater. The Deltapilot and Waterpilot pressure transmitters for hydrostatic level measurement offer the right solution in tanks or wells, submersible or installed outside a vessel.
The Contite sensor is especially developed for hydrostatic level measurement. With its protection for the sensor and cell electronics, the Contite sensor is a convincing solution in the event of severe moisture and condensate formation. The measuring element is hermetically sealed between the process membrane and measuring membrane. Hydrostatic level devices are also available with capacitive, oil-free ceramic measuring cells which are typically used in the process and environmental industries.

Benefits :

• Maximum plant safety provided by one-of-a-kind, condensate-proof Contite measuring cell
• Contite cell offers very good reproducibility and long-term stability even after temperature shocks
• The ceramic cell has extremely good chemical compatibility and high mechanical stability thanks to ultra-pure 99.9% ceramic
• Robust ceramic membrane with integrated membrane breakage detection - also suitable for vacuum applications
