Live concentration data supported higher solids production

Mean solids rose from 24.63% to 33.54% after operators could see the live reading; solids held 60% more stable. Results vary by dredge, material and how the crew uses the data.

What the meter watched

The Red Meter sat on the discharge line. Over several days, through startup and steady running, the study logged percent solids, discharge pressure, flow and temperature.

Unguided startup against the guided run

On this dredge, the December 2025 study recommended a 33 to 38% solids band at a minimum flow of 0.41 m3/s, with pressure of about 57.8 psi as a secondary check. Results vary by dredge, material and how the crew uses the data.

Stable readings from 28 °C down to 16 °C

Ambient temperature fell from 28 °C to 16 °C and the readings stayed stable. Once operators used the meter, morning and afternoon shifts reached the same high-efficiency band.
