Model 803 ROV Electromagnetic Current Meter

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The Model 803 is designed specifically for use on ROVs and other underwater vehicles, providing real time relative water velocity information for pilots. It may be fitted to ROVs to provide actual through the water speeds, or fitted to Tether Management Systems to give measurement of local flow conditions. Measurements are updated every second and the ROVLog™ software provides a graphic and data display, and enables data to be logged to disk.

Electromagnetic sensors use the Faraday Principle to measure the water speed

The Model 803 ROV Current Meter is a unique instrument, providing ROV pilots with relative water velocity data in real time. It may be fitted to ROV’s to provide actual through the water speeds, or fitted to Tether Management Systems to give a measurement of local flow conditions.

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. The data is updated at regular intervals (user selectable), to provide X and Y axis flow information: the X axis is the flow across the vehicle and the Y axis is flow into the vehicle.

The lightweight design of the instrument leads to minimal effect on the vehicle balance, yet permits a depth rating of up to 3000m (titanium version).

Available as a complete self-contained instrument, or with a separate sensor and electronics package, or even as an OEM system, 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 item in the sensor package.
