Retrofitting can be challenging, and the cost of installing certain types of ballast water treatment systems can sometimes exceed the actual cost of the system itself. That’s why, for us, purpose-built integration (filtration + UV within one compact unit) was the optimal solution. And continual innovation – such as our new integrated flow meter – is enabling us to further reduce footprint and simplify the installation process.

A flow meter is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. In ballast water treatment, a flow meter is required to ensure that the water is being treated properly and within the certified range limit specified on the Type Approval certificate.

However, the auxiliary flow meters that are typically used for ballast water treatment require a minimum of five diameters of straight pipe run between it and the treatment unit outlet. This adds unnecessary complexity to the installation process and increases the total footprint of the system, so we set out to find a better, more efficient way to measure flow.

We wanted to make flow monitoring on the Trojan Marinex Ballast Water Treatment (BWT) system easier, intuitive and space-saving. So we worked closely with McCrometer – a leading global flow instrumentation specialist – to engineer, and manufacture a flow metering solution that better meets the unique needs of ballast water treatment.

Now, after months of collaboration and exploration, we are excited to unveil our custom solution to you: an integrated electromagnetic flow meter.

The Benefits

  • Pre-installed, pre-wired and factory-calibrated
  • Eliminates the need for an auxiliary flow meter
  • Eliminates the need for interconnections between the flow meter and treatment unit
  • No recalibration necessary for the life of the flow meter or treatment unit
