Why Level Measurement Matters

Level is one of the most measured parameters in water treatment. It controls pump sequencing, prevents dry-running, mana

Engineered Performance

Every system is designed for your specific wastewater characteristics, flow profile, and effluent targets. No off-the-shelf assumptions — just validated process engineering.

Proven Reliability

Equipment selected from manufacturers with proven field performance in similar applications. Duty/standby arrangements and robust construction minimise unplanned downtime.

Environmental Compliance

Design targets are set at 50-70% of consent limits, providing a safety margin for process variation. Continuous monitoring and automated reporting demonstrate compliance.

Operator Friendly

Intuitive controls, clear instrumentation, and accessible maintenance points reduce training requirements. Standard operating procedures written in plain language.

Technical Support

Direct access to our process engineers for operational advice, troubleshooting, and optimisation. Remote diagnostics and rapid on-site response keep your plant running.

Quality Assurance

Materials certified to EN 10204 3.1, welding procedures qualified to ISO 9606, and pressure testing to 1.5x design pressure. Full traceability from mill to commissioning.

Level Sensor Technologies

Contact vs. Non-Contact Measurement

Ultrasonic

Non-contact sensors ideal for open tanks, sumps, and chemical storage. Cost-effective and easy to install.

  • Accuracy: ±0.25 – 1%
  • No media contact
  • Affected by foam & vapour
  • Wide measurement range

Hydrostatic

Submersible pressure transmitters that measure liquid head. Robust, simple, and excellent for deep tanks and wells.

  • Accuracy: ±0.1 – 0.5%
  • Immune to surface turbulence
  • Can foul in viscous media
  • Easy calibration

Radar

Guided-wave or free-space radar for challenging applications with foam, vapour, or high temperature.

  • Accuracy: ±2 – 5 mm
  • Ignores foam & vapour
  • Higher initial cost
  • Minimal maintenance

Capacitance

Probes that detect level changes by measuring capacitance between the probe and the tank wall. Good for chemicals and sludge.

  • Handles coating & build-up
  • Suitable for small tanks
  • Requires dielectric constant knowledge
  • Point or continuous

Float Switches

Simple, reliable point-level detection for pump control and high/low alarms in sumps and tanks.

  • Low cost & simple
  • Reliable for pump control
  • Only point-level (on/off)
  • Mechanical wear possible
