Hydrostatic level measurement

We have been using the extensive range of Endress+ Hauser hydrostatic pressure transducers to solve the level problems of industry in Northern Ireland for more than twenty years. With models designed specifically for the Waste/ Water, Pharmaceutical, Food and Beverage industries where even the most rugged instruments are tested to the limit we have proved time and again that Endress can out perform all the competition.

Hydrostatic level measurement

Continuous level measurement in liquid applications with pressure sensors

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.

Hydrostatic level measurement: Measuring Principle

Contite cell: The measuring cell is absolutely protected between the process isolating diaphragm and the rear isolating membrane. Also it is absolutely insensitive to condensation and aggressive gases.

Ceramic cell: The ceramic sensor is a dry sensor, i.e. the process pressure acts directly on the robust ceramic process isolating diaphragm and deflects it. A pressure-dependent change in capacitance is measured at the electrodes of the ceramic substrate and the process isolating diaphragm.

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
