Why Pressure Measurement Matters

Pressure data is critical for pump protection, filter condition monitoring, and pipeline integrity. Differential pressur

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.

Pressure Instrument Types

Transmitters, Switches, and Gauges

Pressure Transmitters

Continuous 4-20 mA or digital output for pipeline, tank, and pump pressure monitoring. Capacitive, piezoresistive, and strain-gauge technologies.

  • Accuracy: ±0.1 – 0.5%
  • Ranges from mbar to 1000 bar
  • HART, Modbus, Foundation Fieldbus
  • Diaphragm seal options

Differential Pressure

Measures pressure drop across filters, strainers, and orifice plates. Essential for condition-based maintenance and flow measurement.

  • Accuracy: ±0.05 – 0.1%
  • Filter clog detection
  • Level measurement in sealed tanks
  • Low differential ranges available

Pressure Switches

Electromechanical or solid-state switches for pump start/stop, alarm activation, and safety interlocks when a threshold is crossed.

  • Adjustable set-points
  • High overpressure tolerance
  • SPDT or DPDT contacts
  • ATEX options available

Vacuum Sensors

Monitor negative pressures in suction lines, vacuum filtration, and degassing systems to prevent pump cavitation and air ingress.

  • Absolute or gauge reference
  • Ranges to -1 bar
  • Corrosion-resistant wetted parts
  • 4-20 mA or switching output

Pressure Gauges

Bourdon tube, diaphragm, and capsule gauges for local indication. Essential for operator rounds and maintenance verification.

  • Accuracy: ±0.25 – 2.5%
  • Liquid-filled options for vibration
  • SS316 or brass wetted parts
  • Back or bottom entry
