Endress+Hauser's highly successful Levelflex M guided microwave measuring unit has now gained DustEx approval from Standards Australia, making it an even more compelling choice for bulk solid applications. As the only level measuring device suitable for use in potentially explosive dusty applications such as grain silos, Levelflex M provides reliable level monitoring, even in the largest bulk solids tanks.
Levelflex M is based on Endress+Hauser's advanced application of the Time of Flight (ToF) principle and well-proven level monitoring technology. It is firmly established as a sophisticated yet low-maintenance solution that delivers continuous, accurate and reliable measurement of levels of bulk solids within containers. Using 'microwave on a rope' instrumentation, it measures the level of the material in a container by sending high-frequency microwave pulses down a probe and then analysing the time it takes the signal to be reflected off the change of dielectric between the surface of the stored material and the air above.
Unlike other measuring systems, Levelflex M is unaffected by surrounding conditions within the storage container, including angles of repose, changes in dielectric, moisture, density, particle size or dust. It is also the only measuring system that provides reliable measurement during noisy and dusty filling. This makes it the ideal solution for measuring the level of both granular and powdery bulk solids. Since the technology has no moving parts, maintenance costs are minimal.
Levelflex M suits a wide range of level measurement applications, including chemical processing, mining and grain and other bulk solids. It is compatible with all tank materials and geometry, and is available with a rod probe, a coaxial probe or a high tensile strength, small-diameter rope probe for silos and tanks up to 35 m tall. All probes are interchangeable, user-replaceable and suitable for use in temperatures up to 400C
.
Direct configuration and system integration are available through Profibus PA or Foundation Fieldbus systems. All models are equipped with the HART communication protocol, ensuring compatibility with any existing analogue topologies.
ToF Tool - Endress+Hauser's state-of-the-art, PC-based Time of Flight software platform - is included free with Levelflex M and enables simple and safe commissioning, maintenance, diagnosis and documentation. Also included is a high-resolution LCD panel, which displays the radar signal as an envelope curve, helps indicate potential trouble spots inside the vessel, and doubles as a programming control panel (with four-line, 80-character display) for on-site set-up and resetting.
The precision, reliability and safety of Levelflex M in measuring powdery and granular bulk solids (and a wide range of liquid media) has been demonstrated in more than 20,000 installations worldwide - including over 300 installations around Australia. 'Especially with this new DustEx accreditation, Levelflex M is unquestionably the measurement solution of choice for bulk solid storage situations,' says John Immelman of Endress+Hauser Australia. 'It offers great features and benefits and superior performance at an affordable price, and we provide the most suitable and economical probe for each particular application.'
