Electromagnetic Systems - Aqua Data Probes

Electromagnetic probe design has proved to be the make or break for companies concerned with flow measurement. Over a decade of development and refinement has resulted in Aqua Data Services producing the most stable and accurate flow meter in the market today giving you the highest resolution of all enabling you take the measurements you want.

For convenience and choice, Aqua Data make two different sizes of probe. Depending on your application you can choose between the RV2 or the RV4.

The rugged RV2 us the general purpose 'workhorse' of the industry measuring 185x49x19mm inc. spigot.

The RV4 was developed for any applications requiring a smaller probe measuring 145x30x15mm inc. spigot.

Cable lengths up to 75m are available as standard.

Calibration

As the electronic properties of the components buried within the strong epoxy resin casing of each probe differ slightly between probes and as the signals that are processed are so small - 1mm/second = 40nV (i.e. 0.000000040 volts), it becomes obvious that each probe needs to be 'standardised'.

To ensure you get the quality and consistent results you need, each probe is individually calibrated at The Solent University in Southampton, UK. All of the calibration is carried out in the 80m tow tank, in which the probes each undergo 13 runs at different but accurate velocities. Software logs the results for each probe, and a calibration table is generated for each probe to automatically and accurately compensate for these variations.

Bespoke Systems - example

A customer approached us with an application to measure the velocity of a fluid of a fluid 300m below ground level, in a borehole.
The resulting prototype (shown) was developed in partnership with the customer and is still in use today.

We have since provided a 150m unit to another customer and similar systems are available as the SENSA -B..
