Miros SM-140 Series User Manual

Summary:
The SM-140/02 RangeFinder is a unique high-performance remote sensor for measurement of air
gap, water level, draught and non-directional wave parameters. It utilizes a microwave radar-based
FMCW (Frequency Modulated Continuous Wave) sweep method for measuring air gap. When
delivered with the optional embedded MRU (Motion Reference Unit) to compensate for vessel
heave, the sensor is named SM-140 WaveFinder. For simplicity the name RangeFinder is used
throughout this document.
The sensor enables data to be easily accessible both locally and remotely using modern IoT
technologies.
The sensor is essential for several types of operations and can be integrated both with local and
remote systems. It can also be complimented with various value adding cloud services from Miros.
This manual provides information for installation, operation and user maintenance.
