Field Calibration of Instruments (sand injection)

Controlled sand injection is the most effective way to verify and calibrate sand monitoring systems under real operating conditions. By introducing a known quantity and distribution of sand into the flow, ClampOn specialists validate that the instrument response matches actual sand production behavior.
This approach ensures that calibration is not based on assumptions or simulations, but on measured response to real sand particles under representative flow regimes.

Field calibration is a complex operation that requires detailed knowledge of acoustic instruments, practical equipment setup, and signal processing in the dedicated Sand Monitor software. ClampOn specialists evaluate and understand how sand response, background noise, flow velocity, and particle characteristics influence the outcome data from sand injections.
Our specialists execute calibration safely and precisely, ensuring that injected sand is measured and accounted for in a controlled and repeatable manner.

During field calibration, ClampOn specialists verify both sand detection sensitivity and quantification accuracy. Measured responses are compared against injected sand volumes to create custom calibration tables for each individual sensor.
This process reduces measurement uncertainty and ensures that sand rate and cumulative calculations reflect real world sand production.

Unlike laboratory tests or theoretical calibration methods, field calibration through sand injection reflects real‑world conditions such as flow regime, pressure, temperature, background noise and flow velocity.
By calibrating instruments while the system is operating normally, ClampOn ensures that measurement performance remains valid during everyday production, not just under idealized conditions.

Following calibration, ClampOn specialists provides a field service report of the performed activities, injected sand quantities, observed responses, and resulting calibration settings. Any identified deviations, limitations, or improvement opportunities are communicated directly to the client.
This documentation provides traceability, supports internal assurance processes, and serves as a reference for future monitoring and optimization activities.

Accurate sand measurement is critical for protecting equipment, managing erosion risk, and optimizing production strategy. Field calibration through controlled sand injection ensures that sand monitoring systems deliver reliable, defensible data when it matters most.
By using ClampOn specialists for calibration, operators secure long‑term confidence in their measurements, reduced operational risk, and maximum value from their sand monitoring investment.
