Phathom - Model S20-SWW -Suspended Solids and Turbidity Sensor
Designed for accuracy in dirty water, measuring a TSS range of 0 – 10 g/L (SiO2). The S-series are immersion sensors and they use direct attenuated light to measure both TSS and turbidity directly.
Get better control and monitoring of your Stormwater run-off. Bringing sophisticated process control suspended solids sensors to Stormwater and Waste
- Four beam self compensating sensor, virtually eliminates drift due to contamination or electronic ageing.
- Immersion style.
- Simple user interface.
- Accurate, repeatable & reliable.
- Low power suitable for remote installations
- Connects directly with 4-20mA and Modbus RS485, or SDI-12
S20-SWW Measurement Range, 0 to 10g/L normal activated sludge
S20-SWW immersion
Immersion style sensors are designed for continuous on-line monitoring of suspended solids in Stormwater monitoring and Waste Water installations.
Sensor calibration
Simple 2 point calibration using simple PC USB interface.
Applications include:
- Stormwater sediment runoff monitoring
- Flocculant dosing and control
- Wastewater monitoring and control

Phathom sensors will work with a 3.7V battery recharged by solar panels, making them ideal for remote deployment.
Phathom sensors can be connected to a local power source.
Phathom sensors will work with a 9-32V battery supply, making them ideal for remote deployment.
You can integrate a Phathom sensor into your existing telemetry through either a 4-20mA, Modbus RS485 or SDI-12 connector. Or click right to see examples of tried and tested systems.
They are leaders in agri-data. Phathom sensors work well with their telemetry solutions.
Industrial communications and data
Instrumatics’ economical communications unit and platform
Gold standard sediment control monitoring
Flotation buoys and devices support Phathom sensors in ponds, estuaries, and larger rivers.
Phathom sensors can be secured outside of the water and immersed into the water in a flume, sump, tank, lift stations or body of water.
Phathom sensors can be integrated into a plumbed system for clarifiers, lamellas, dewatering systems or raw water supply.
Unlike single-beam sensors that require constant cleaning, Phathom sensors typically only need occasional cleaning at most because their multi-beam technology self-compensates for accumulated dirt unless they get completely clogged. That means they usually don’t require any attachment.
