Endress+Hauser introduces the Micropilot FMR5X series of free space radar level transmitters.
Endress+Hauser introduces the Micropilot FMR5X series of free space radar level transmitters. The FMR5X has software with multi-echo tracking algorithms and functions to suppress interference echoes, providing accuracy up to ±0.078 in. for level measurement of bulk solids.
FMR5X transmitters can be loop powered by 4-20mA in a two-wire arrangement, a four-wire configuration, and with HART, Profibus PA, and Foundation Fieldbus. Optionally the transmitter is available with two independent configurable 4-20 mA outputs. Advanced diagnostic algorithms can be used for either build-up or foam detection with either the switch or additional 4-20mA output.
The FMR5X can be used to measure level or volume with a built-in 32-point strapping table. It measures the distance from the process connection to the product surface. However, the FMR5X is equipped with multi-echo tracking algorithms that ensure that interference echoes—for example, echoes from edges, weld seams, other instruments, baffles, agitators, and heating coils are not interpreted as level echoes. Multi-echo tracking uses self-learning algorithms that build short- and long-term history to check the echoes for plausibility and increased reliablity.
A linearization table of up to 32 points can be entered either manually or semi-automatically. This function provides a linear 4-20mA output signal for spheres, horizontal cylindrical tanks and vessels with a conical outlet. Linearization can also be used to convert the level measurement into volume or mass engineering units.
Standard FMR5X models with 0.078 inch accuracy are available for measuring solids in basic applications in the chemical, oil & gas, life science, food, water/wastewater, and energy industries. Multiple FMR5X transmitters can be installed in the same tank without interference among them because the transmitter pulses are statistically coded.
