Water System Calibration Services

Accurate, compliant instrumentation calibration for reliable water system performance

Precise measurements are critical in water treatment. Whether you’re monitoring flow rates, pressure, pH, or conductivity, inaccurate readings can lead to poor system performance, non-compliance, and unnecessary downtime.

At AllWater Technologies, we provide expert-led water system calibration services for a wide range of industrial and commercial water treatment systems. From sensor calibration to full instrumentation calibration, our experienced engineers ensure your data is reliable, your processes are safe, and your system is always operating at peak efficiency.

Why Calibration Matters

Modern water treatment systems rely heavily on sensors and instruments to monitor and control process parameters. Over time, these instruments drift out of specification due to wear, fouling, or environmental factors. Without regular calibration, even small inaccuracies can result in:

  • System inefficiencies or failures
  • Incorrect chemical dosing
  • Poor product quality or compliance breaches
  • Increased energy or water consumption
  • Missed alarms or false alerts

Our water system calibration services are designed to eliminate these risks by verifying, adjusting, and certifying your instruments to perform within defined tolerances.

Our support includes

Telephone & remote diagnostics for rapid fault identification

System troubleshooting and root cause analysis

Planned service visits tailored to your production schedule

Guidance on optimisation, upgrades and retrofit options

Ongoing training and user support post-installation

On-site engineering support from qualified specialists

What’s Included in Our Calibration Services?

We offer a full suite of instrumentation calibration services, tailored to your system configuration and industry requirements. Our services are available on a one-off or scheduled basis, and can be integrated into your service agreement for added convenience.

Calibration services include:

  • Site audit and instrument register review
  • Sensor calibration for pH, conductivity, chlorine, turbidity, and ORP
  • Flow meter calibration (magnetic, ultrasonic, turbine, etc.)
  • Pressure and temperature sensor calibration
  • Level and dosing controller calibration
  • Calibration of analogue/digital transmitters and recorders
  • Adjustment, reconfiguration, and firmware updates (if required)
  • Certificate of calibration with traceable references
  • On-site logging, inspection, and system documentation updates

Expert Engineers, Trusted Results

Our calibration work is carried out by trained engineers with extensive experience in instrumentation calibration for water treatment systems. Each calibration is performed using certified reference equipment and documented in line with relevant standards.

You can rely on us for:

  • UKAS-traceable calibration references
  • Adherence to ISO 9001:2015 Quality Management Systems
  • Full compliance with HSE, EA and industry-specific regulations
  • Minimal disruption to production during site visits
  • Clear, concise calibration reporting and certificates

Whether you need annual verification, a reactive check following system issues, or calibration as part of a larger commissioning or maintenance schedule, we deliver consistently accurate and auditable results.

Systems and Instruments We Calibrate

AllWater Technologies provides calibration services for a wide range of instruments used in water and wastewater treatment systems. We support both standalone instruments and those integrated into larger control and automation platforms.

Typical calibration targets include:

  • pH sensors and probes
  • Conductivity and TDS sensors
  • Flow meters (ultrasonic, electromagnetic, turbine)
  • Pressure and temperature transmitters
  • Turbidity and chlorine sensors
  • Chemical dosing controllers and pumps
  • Tank level sensors
  • PLC/SCADA interface signals and alarm

We calibrate instruments supplied by leading manufacturers including Siemens, ABB, Endress+Hauser, Burkert, Suez, and more.

When Should Calibration Be Carried Out

We recommend scheduling calibration at least once per year for most water treatment instruments – more frequently if your system operates under extreme conditions, or where water quality compliance is critical.

Calibration is also essential in the following scenarios:

  • During new system commissioning
  • After instrument replacement or relocation
  • Following unexpected system behaviour or alarm trends
  • Prior to external audits or compliance inspections
  • As part of scheduled preventative maintenance

For clients with service agreements, calibration services can be bundled into routine site visits to ensure ongoing performance without additional disruption.

Flow Meter Calibration Services

Flow meters are a cornerstone of water system management – used to monitor throughput, control dosing, and manage system balance. If a flow meter drifts from specification, the knock-on effects can be significant.

We offer specialist flow meter calibration services for:

  • Magnetic flow meters (magmeters)
  • Ultrasonic flow meters
  • Turbine flow meters
  • Vortex and variable area (rotameter) devices

Each calibration includes on-site verification against reference equipment, error adjustment, and detailed reporting. We also assess sensor placement, wiring integrity, and signal output as part of a full instrument health check.

Sensor Calibration: Confidence in Every Reading

Sensors are exposed to fluctuating water quality, temperature, and chemical dosing conditions. Without regular sensor calibration, drift is inevitable – leading to inaccurate data and inconsistent system control.

We carry out precise calibration for:

  • pH
  • ORP/Redox
  • Conductivity
  • Dissolved oxygen
  • Free and total chlorine
  • Turbidity

Our engineers use certified calibration fluids and gas references to ensure sensors are correctly adjusted and functioning within spec. Where required, we also supply and replace fouled or expired sensors as part of our end-to-end service.

A Long-Term Partner in Calibration and Support

Calibration isn’t just about ticking a box – it’s about ensuring long-term system performance, process safety, and operational insight. That’s why our calibration services are part of a broader partnership approach, supporting your equipment across its lifecycle.

Benefits of working with AllWater Technologies include:

  • Single point of contact for installation, servicing, and calibration
  • Calibration services integrated into service contracts
  • Fast response for urgent or compliance-critical checks
  • Dedicated portal access for calibration records and reports
  • Optional remote monitoring and diagnostics
