The areas of measurement calibration are :

(i)  Differential Pressure

(ii)  Static Pressure

(iii) Temperature

(iv) Flow Totalizer

These measurements directly affect the calculations on the amount of gas that pass through pipelines.  These parameters are generally measured with individual transmitters for each one or with one multi variable transmitters. If any of these are out of calibration it can cost the company or the customer buying from that company.
