Field Calibration Methodology

In order to keep your flow instruments operating at like new factory specifications, Vortex Technologies technicians will install a non-invasive, NIST traceable reference meter on the same line that the meter in need of calibration is installed. Initial readings for each device are recorded and any difference in flow rate between the reference device and the meter under test is noted. A percentage correction factor (k factor) is calculated. The meter under test is then adjusted to match the reference meter. For critical processes, the process flows can be changed and a multi-point curve can be generated to show the operational characteristics of the meter under test at various flow rates and how it relates to the reference meter.
