Meet the Royce Aqua 22
Portable sludge measurement, made clear.
Measure sludge blanket depth and suspended solids with one lightweight handheld instrument built for routine wastewater checks.
Measure depth and suspended solids without changing instruments.
Sludge blanket depth
Locate the blanket from 0 to 10 metres using the Aqua 22’s integrated hydrostatic depth measurement.
MLSS and suspended solids
Check mixed liquor and suspended solids concentrations up to 20,000 mg/L at the tank side.
Ready for field use
Work confidently outdoors with a daylight-readable display, rechargeable power and straightforward handheld operation.
Faster tank-side checks. Clearer process decisions.
The Royce Aqua 22 brings sludge blanket depth and solids concentration together in one handheld instrument, helping operators complete routine checks efficiently and act on clear process information.
Locate the blanket
Measure sludge depth from 0 to 10 metres
Lower the sensor into the tank and use hydrostatic pressure measurement to identify sludge blanket depth quickly and consistently.
Check solids concentration
Measure MLSS and suspended solids up to 20,000 mg/L
Use one handheld instrument for mixed liquor and suspended solids checks, helping operators gather useful process information during routine rounds.
One portable meter, built around everyday wastewater checks.
01.
Sludge blanket depth
Measure blanket depth across a 0 to 10 metre range using the integrated hydrostatic pressure sensor.
02.
Mixed liquor suspended solids
Check MLSS concentration directly at the process, with a measuring range up to 20,000 mg/L.
03.
Suspended solids concentration
Use the same portable platform for routine suspended solids measurements in wastewater applications.
04.
Interchangeable smart sensors
Calibration data stays with each serialised sensor, allowing sensors to be exchanged without recalibrating the handheld.
05.
Daylight-readable display
Read measurements clearly during outdoor rounds on a display designed for bright, real-world working conditions.
06.
UK service and calibration
Access product support, servicing and calibration through Process Measurement and Analysis in the UK.
What operators need from a portable sludge meter
Royce Aqua 22 brings sludge blanket depth and suspended solids measurement together in one handheld instrument for routine wastewater process checks.
“See sludge blanket depth directly at the tank side, with readings from 0 to 10 metres.”
Depth measurement
Hydrostatic sensor
“Check mixed liquor and suspended solids up to 20,000 mg/L without carrying a separate instrument.”
Solids measurement
MLSS and suspended solids
“Exchange a serialised sensor without recalibrating the handheld meter.”
Smart sensor platform
Calibration stays with the sensor
0–10 m sludge blanket depth. Use hydrostatic pressure measurement to locate the blanket across tanks and clarifiers.
Up to 20,000 mg/L. Measure mixed liquor and suspended solids with one portable field instrument.
Built for practical wastewater measurements
Royce Aqua 22 brings sludge blanket depth and suspended solids measurement together in one handheld instrument for routine wastewater process checks.
Key measuring ranges
0–10 m
Sludge blanket depth
Hydrostatic depth measurement helps operators locate the sludge blanket during routine checks.
20,000 mg/L
Suspended solids range
Measure MLSS and suspended solids concentration at the tank side with a single handheld meter.

Smart sensors, simple changeovers
Calibration stays with the sensor
Each serialised sensor stores its own calibration data, supporting consistent measurements and easier servicing.
Interchangeable by design
Exchange compatible sensors without recalibrating the handheld unit, helping reduce disruption in the field.
Discover the practical features that make sensor changes, field measurements and routine operation easier.
Made for tank-side work
Designed for routine rounds
Lightweight, rechargeable and easy to handle, the Aqua 22 is designed for routine rounds in wastewater treatment environments. Its daylight-readable display keeps measurements clear outdoors.
Clear readings outdoors
The daylight-readable display helps operators see depth and solids measurements clearly during outdoor tank-side checks.
Rechargeable and portable
Rechargeable power and a lightweight handheld format make the Aqua 22 practical to carry between clarifiers, settlement tanks and other wastewater process points.
