With multi-echo tracking algorithms and functions to suppress interference echoes, the Endress+Hauser Micropilot FMR5X free-space radar level transmitter measures the level or volume of liquids and bulk solids products in metal or plastic tanks, stilling wells or other vessels up to 131-ft. high with accuracy up to +/-0.078 in. A linearization table of up to 32 points provides a linear 4 to 20mA output signal for spheres, horizontal cylindrical tanks and vessels with a conical outlet. Communication options include HART, Profibus PA and Foundation Fieldbus. Developed to SIL2 according to IEC 61508, the transmitter can be used with homogeneous redundancy up to
