    Technical Information

    Levelflex M FMP40Guided Level Radar Smart Transmitter for- Level Measurement in Bulk Solids and Liquids - Interface Measurement in Liquids

    Application

    Level measurementContinuous 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.

    The HART with 4 to 20 mA analog, PROFIBUS PA and FOUNDATION Fieldbus protocols are available for system integration.

    Application in safety related systems (overspill protection) with requirements for functional safety up to SIL 2 in accordance with IEC 61508/IEC 61511-1.

    WHG approval

    Interface measurementContinuous 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

    and temperature 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 for system integration.

    Your benefits

    Probes are available with threaded process connections from " and flanges from DN40 / 1". Rope probes, above all for measurement in bulk solids,

    measuring range up to 35 m. 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

    diagnosis. Easy remote operation, diagnosis and measuring point

    documentation with the free operating program supplied.

    Optional remote display and operation. With coax probes the measurement is independent of

    internals in the tank and of the installation in the nozzle.

    Probe rod and probe rope can be replaced/shortened. Approvals: ATEX, FM, CSA, TIIS, NEPSI, IECEx.
