At the core of the ISFMD system is the ISA500 acoustic sensor.
The ISA500 provides exceptionally long range and high accuracy measurement capability. The unit has a 1mm accuracy – allowing precise distance measurements to be made.
The ISA500 also has an integrated Attitude and Heading Reference System (AHRS). This provides highly stable Heading, Pitch and Roll readings, allowing a clear understanding of FMD probe position at time of reading.
When not being used for FMD, the ISA500 sensor can be used as an Altimeter, Echo Sounder or as an Attitude & Heading Reference System.
