Cleaning and maintenance without docking, Thru-Hull Sound Velocity Sensor allows the probe to be deployed through the vessel’s hull and safely recovered.
It is particularly useful for multibeam applications where knowledge of the sound velocity adjacent to the multibeam transducer is necessary. The probe is also available with an optional PRT temperature sensor.
Valeport’s unique digital time of flight sound velocity sensor. Advanced composite, titanium and polycarbonate construction, together with the digital sampling technique give unmatched levels of accuracy.

The Thru-Hull SVS uses a PN16 ball valve, nominal 100mm bore, operated using a 90° turn lever. The valve is normally supplied in aluminium bronze, and comes complete with full Germanischer Lloyds certification (or equivalent) to allow it to be fitted to the vessel.

The valve should be fitted to the vessel in dry dock, and left in a closed position. The mounting sleeve is fitted to the valve, and the SVS secured within the sleeve. The SVS features O-ring seals to the sleeve, so once it is fitted, the valve may be opened and the probe pushed into position. To recover the probe, withdraw it into the sleeve, close the valve, and disassemble the sleeve.
