Level Pressure Flow Temperature Liquid Registration Systems Services Solutions Analysis Components Technical Information Guided Level Radar Continuous Level Transmitter for - Level Measurement in Bulk Solids and Liquids - Interface Measurement in Liquids Rod probe Coax probe Rope probe Level measurement Continuous level measurement of powdery to granular bulk solids e.g. plastic granulate and liquids. ■ Measurement independent of density or bulk weight, conductivity, dielectric constant, temperature and dust e.g. during pneumatic filling. ■ Measurement is also possible in the event of foam or if the surface is very turbulent. FOUNDATION Fieldbus protocols are available for system integration. ■ Application in safety related systems (overspill protection) with requirements for functional safety up Interface measurement Continuous measurement of interfaces between two liquids with very different dielectric constants, such as in the case of oil and water for example. ■ Measurement independent of density, conductivity ■ Electronics version for the simultaneous measurement of the level of interfaces and the total level in liquids. The HART with 4 to 20 mA analog protocol is available for system integration ■ Special version for the measurement of the level of interfaces at a constant total level. The PROFIBUS PA and FOUNDATION Fieldbus protocols are available Your benefits Probes are available with threaded process connections from %" and flanges from DN40 (1V2"). ■ Rope probes, above all for measurement in bulk solids, ■ Rod probes, above all for liquids ■ Coax probes, for liquids ■ Simple, menu-guided onsite operation with four-line plain text display. ■ Onsite envelope curve on the display for easy ■ Easy remote operation, diagnosis and measuring point documentation with the free operating program ■ Optional remote display and operation. ■ With coax probes the measurement is independent of internals in the tank and of the installation in the ■ Probe rod and probe rope can be replaced/shortened. ■ Approvals: ATEX, FM, CSA, TIIS, NEPSI, IECEx.

Levelflex M FMP40 Function and system design Measuring principle The Levelflex is a "downward-looking" measuring system that functions according to the ToF method (ToF = Time of Flight). The distance from the reference point (process connection of the measuring device, → ä 43) to the product surface is measured. High-frequency pulses are injected to a probe and led along the probe. The pulses are reflected by the product surface, received by the electronic evaluation unit and converted into level information. This method is also known as TDR (Time Domain Reflectometry). flange: reference...

Levelflex M FMP40 Interface measurement When the high-frequency pulses hit the surface of the medium, only a percentage of the transmission pulse is reflected. In the case of media with a low DC1, in particular, the other part penetrates the medium. The pulse is reflected once more at the interface point to a second medium with a higher DC2. The distance to the interface layer now can also be determined taking into account the delayed time-of-flight of the pulse through the upper medium. c = c0 = 300 000 km/s total level DK1 C1 = C0 DK1 interface level DK2 L00-FMP4xxxx-15-00-00-en-007...
