Our Flow Calibration Services

Precise flow measurement is critical across industries such as chemical processing, water and wastewater treatment, pharmaceuticals, food and beverage production, and energy generation.

When flow instruments drift out of specification, the effects can be far-reaching, from process inefficiencies and product quality problems to environmental compliance risks and unnecessary financial loss. The Accredited Labs network offers complete flow calibration services to keep your instruments performing within their required accuracy ranges.

Our Process

Flow calibration involves verifying and adjusting instruments that measure the rate of fluid movement through pipes, channels, or other controlled pathways. Each instrument is compared to certified reference standards with known, traceable flow rates to identify any deviations from its intended performance.

Experienced technicians assess each device across its full operating range under precisely controlled flow conditions, document all variations, and may make the adjustments needed to restore accuracy. If an instrument cannot be restored to the required accuracy range, you receive detailed reporting with the data necessary for maintenance planning, corrective action, or replacement decisions.

All flow calibrations follow internationally recognized protocols that promote consistency, reliability, and full measurement traceability. Every instrument is returned with documentation linking its accuracy to national flow measurement standards—supporting quality management systems, regulatory requirements, and continuous process control.

Types of Flow Measuring Instruments We Calibrate

Our comprehensive flow calibration services cover the complete spectrum of flow measuring technologies used across industries:

Magnetic Flow Meters: These versatile instruments measure conductive fluid flow using electromagnetic principles. They require calibration of both the flow sensor and signal processing electronics to ensure accurate measurement across varying fluid conditions and flow rates.
Turbine and Positive Displacement Meters: Mechanical flow meters measure flow through rotating elements that require calibration to account for wear, viscosity effects, and mechanical tolerances that affect measurement accuracy over time.
Ultrasonic Flow Meters: These non-invasive instruments use acoustic signals to measure flow and require calibration of timing circuits, signal processing algorithms, and transducer characteristics to maintain measurement accuracy across different fluid types and pipe conditions.
Vortex Flow Meters: These instruments measure flow by detecting vortices created by flow obstructions. Calibration ensures accurate vortex detection and frequency measurement across the instrument's flow range and various process conditions.
Differential Pressure Flow Meters: Including orifice plates, venturi tubes, and flow nozzles, these instruments calculate flow from pressure differences. Calibration verifies both the pressure measurement accuracy and flow calculation algorithms.
Thermal Mass Flow Meters: These instruments measure flow by detecting heat transfer effects in flowing fluids. Calibration ensures accurate temperature measurement, heating element control, and flow calculation across different gas compositions and process conditions.
Coriolis Mass Flow Meters: These precision instruments measure mass flow directly through Coriolis force effects. Calibration involves verification of frequency measurement, phase detection, and mass flow calculations across varying fluid densities and viscosities.
Variable Area Flow Meters: Including rotameters and other variable area devices, these instruments require calibration to ensure accurate flow indication across their measurement range and various fluid conditions.
Open Channel Flow Measurement: Weirs, flumes, and other open channel flow measurement devices require calibration of level measurement systems and flow calculation algorithms to ensure accurate flow determination.
