ISFMD Flooded Member Detection System

FMD Probe

At the core of the ISFMD system is the ISA500 ultrasonic sensor probe.

Utilising a fully digital correlation technique; the probe provides exceptionally long range and high accuracy measurement capability.  The probe has a 1mm range measurement accuracy – allowing precise distance measurements to be made.

For each member under test the probe acoustic settings are automatically configured to suit the member. This flexibility ensures that both small and large members can be tested accurately and repeatedly by the ISFMD system.

The probe utilises an in-built 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.
 

Cable Reel

Available with either a 100 or 200 meter cable reel allows the ISFMD system to be easily deployed by a Diver.

Cable is supplied on a robust metal reel, terminated for use with the ISFMD probe and ISFMD Topside Interface Box.

All connections are plug and play allowing for quick and simple setup of the system.
 

Topside Interface Box

The ISFMD Topside Interface Box allows ‘plug and play’ connection of all system components.

The topside cable reel connection plugs into the ‘ISA500’ socket.

The supplied topside power supply plugs into the ‘PWR’ socket.

A link to the topside computer, running the seaView software, is provided via the ‘USB’ port.

Each connection can only plug into its allocated socket – simplifying the setup process.
 

Powerful Software

The seaView FMD application provides all that is required to conduct an underwater Flooded Member Survey.

The main screen shows the FMD sensor probe orientation, all echoes received together with a liquid level reading (if liquid is present).  Each reading is accompanied with a energy level and correlation value.  These values provide a quality check on each reading obtained.

A graphic representation of the underwater member is configured by the user to replicate the item being tested.

When configuring the member under test, the user enters in the diameter of the member.  This diameter is used to automatically configure the FMD probe to utilise the most appropriate acoustic settings for the member under test.  The ISFMD system varies the transmitted pulse length, minimum range, maximum range and various other parameters to specifically suit the member under test.

Measurements made along the underwater member are then recorded at defined points and shown visually on screen.

Upon completion of the survey, all data collected is saved and output in a Flooded Member Detection report.
