Methods for continuous level measurement in solids applications include guided radar, ultrasonics and noncontact radar to ensure systems designers get the "best fit" for their applications.

Accurate and reliable level measurement is critical to optimising plant performance and efficiency.

Endress + Hauser offers a range of methods for continuous level measurement specially designed for solids applications, including guided radar, ultrasonics and noncontact radar to ensure systems designers get the "best fit" for their applications.

Perfect for use in silos and storage tanks, Levelflex M guided radar provides reliable level measurement of bulk solids, even during pneumatic filling when thick dust clouds can occur.

Working on microimpulse technology, it is independent of air disturbance and changes in product property such as humidity, density and dielectric constants and its high sensitivity means it can be used in the measurement of fine-grained solids such as plastic powder and granules.

Where measurement using sensors in contact with the product are not possible due to wear, damage and cost implications, the noncontact Prosonic S ultrasonic transmitter offers the ideal solution.

It can be mounted in a safe position well above a hopper or silo and with its signal conditioning it measures any surface, as well as handling noise and dust generation.

The sensor can also play an integral part for the level control of a material transfer conveyer or grading and screening plant.

Simple to operate via its menu-guided plain text display, there are no codes to decipher so users can concentrate on getting the job done.

Even better, the free ToF Tool operating software provides reliable commissioning, maintenance and documentation of the measuring point.

Because of the extreme noise and dust generated by many bulk solids applications (eg crushers), noncontacts methods, such as the Micropilot M FMR250, provide the best results.

Maintenance-free, Micropilot radar devices are unaffected by pressure, temperature, gas layers or condensation and offer high accuracy measurement.

EEx ia, EEx D and SIL2 certified, the on-screen envelope curve allows analysis without a laptop - a real benefit in hazardous areas.

Measuring up to 70m, Micropilot M is ideal for high silos containing dusty solids such as cement, animal feed or even highly abrasive solids such as ferrite.
