Advanced Flow Sensor Calibrations

Advanced Processing provides the highest level of standard calibration for all equipment designed for the measurement of flow. Flow sensors measure the flow rate of a fluid, liquid, or gas when it passes through a confined transmission system. There are a variety of instruments that use the physical properties of liquids and gas to measure them most accurately and economically. The instruments operate using ultrasonic, electromagnetic, Karman vortex, paddlewheel, floating element, thermal, and differential pressure methods of measurement. They all most be calibrated to make sure the process is accurate and stable.

Mass Flow Meter Calibrations

APS performs mass flow meter calibrations to the finest of tolerances in gas measurement. Because the mass flow controller is a specific inline device it is critical that is regularly maintained and calibrated in laboratories or production settings. The mass flow sensor requires calibration for both it’s measurement and control functions all the while tight thermal/pressure control is maintained for consistent volumetric metering.

• Burkert
• Bronkhorst
• Porter

Volumetric Flow Meter Calibration

APS performs NIST traceable ISO 17025 sensor calibration in analytical laboratory and in industrial process applications. We can quickly accommodate on-site equipment or equipment overnighted into our laboratory for rapid calibration and instrument turnaround. A sampling of instruments we regularly calibrate are digital force gauge, load cell, balance, vernier caliper, height gauge, torque wrench, torque analyzer, torque tester, torque screwdriver, and manometer. Torque wrench calibration is a common request where we expedite service. Several applications of balance calibration, load cell calibration, torque calibration and sensor calibration involve our setting up an initial IOPQ process qualification and validation.

Leading brands calibrated and serviced:

• Copley
• TSI

In-Line Flow Meters

APS works with NIST traceable ISO 17025 in-line flow meter calibration in analytical laboratory and in industrial process applications. These meters work on a variety of physical properties that include acoustic, optical, volumetric, or gravimetric methods.

Acoustic Flow Sensor - Inline or non-invasive acoustic flow sensor calibration

APS performs acoustic flow meter calibration that incorporates the geometric calibration of the tube or pipe the liquid passes through. APS performs acoustic flow sensor calibration on flow meters, bubble sensors, and level sensors using this technology. Inline or non-invasive available.

Optical Flow Sensor - Inline or non-invasive optical flow sensor calibration

APS performs NIST traceable ISO 17025 optical flow sensor calibration in analytical laboratory and in industrial process applications. APS calibrates these sensors whether the optical flow meter measures through optical fiber interferometry, optical hot-wire anemometry, or scintillation. Inline or non-invasive available.
