Micropilot FMR20 Modbus RS485 Measuring principle The Micropilot is a "downward-looking" measuring system, which functions according to the time-offlight (ToF) method. It measures the distance from the reference point R to the product surface. Radar pulses are emitted by an antenna, reflected off the product surface and received again by the radar system.
PAGE 7
Micropilot FMR20 Modbus RS485 Input Measured variable The measured variable is the distance between the reference point and the product surface. The level is calculated based on E, the empty distance entered. Measuring range Maximum measuring range • Device with 40 mm (1.5 in) antenna: 10 m (33 ft) • Device with 80 mm (3 in) antenna: 20 m (66 ft) Installation requirements • • • • • • Recommended tank height > 1.5 m (5 ft) for media with low εr value Open channel minimum width 0.5 m (1.
