Professional Calibration Services
Calibration of flow devices may be critical to the safe operation of machinery or proper operation of the end application. While in some situations the flow accuracy is not critical, it may be critical for others. Calibration services for flow meters typically take two forms; viscosity calibration and calibration of the output signal to match a specific flow range. Calibration services for flow switches typically mean adjustment of the low flow trip signal (often known as the interlock) to a precise flow at a specific viscosity.
Proteus Industries is one of the few suppliers with its own calibration lab, and includes a standard 3-point calibration service for each and every flow meter, ensuring the integrity of end application. The 3-point calibration provides test results in the low, mid and high end of the flow range (see example calibration sheet below). This standard calibration of flow devices occurs in water at a nominal temperature of 25 degrees Celsius. An example of a typical 3-point calibration certificate which is provided with Proteus devices is shown below;
