Yokogawa Network Solutions presents a tutorial on basic curve fitting or function finding as a replacement for look-up tables and linear interpolation of intermediate values. This set of videos is intended as a supplement to the original paper: "Simplified Curve Fitting for Renewable Energy Data Collection and Control". Two examples are covered that include approximating a flow rate correction factor for methane with a thermal mass flow meter and correcting the inclinometer reading on a concentrated solar thermal tracking system for gravimetric sag on the heat transfer fluid receiver. The tutorial set shows the original look-up tables for correction factors, generates a matching function using ZunZun (free function finder and curve fitting site), and compares the resulting function output against the original values.
For industrial DAQ applications, the MW100 offers scalability and can operate either standalone or integrated as a node within a larger automated system including SCADA or DCS.
