Valeport BFM 803 Current Meter – Available for rental, hire and purchase from Ashtead Technology.

The Model 803 ROV Direct Reading Current Meter is a unique instrument, providing ROV pilots with relative water velocity data in real time. It may be fitted to ROVs to provide actual through the water speeds, or fitted to Tether Management Systems to give a measurement of local flow conditions. The selection of output options make interfacing easy, and data may be displayed using the software supplied. Available in both 500m acetal and 3000m titanium versions, the Model 803 is an extremely durable, reliable method of measuring current speeds in a wide variety of underwater vehicle applications.

This instrument is the result of combining Valeport's proven current sensing technology with the knowledge and experience of some of the UK's leading ROV manufacturers and operators. The concept is simple - the Model 803 consists of a Valeport 2 axis electromagnetic flow sensor, with processing electronics capable of giving a variety of output formats for easy interface to almost any system.

The sensor should be mounted in clear flow on the ROV or TMS. When power is applied to the sensor, it measures the water velocity in 2 axes across the sensor surface. This data is updated at 1 second intervals, to provide X and Y axis flow information: the X axis is flow across the vehicle, and the Y axis is flow into the vehicle.

This data can either be taken into a separate logging package, or displayed and logged to PC using the ROVLog Windows software provided. The Model 803 will appeal both to operators who wish to improve their existing vehicles, and to manufacturers who want to offer it as an additional parameter in the sensor package.
