You give to us we will use calibration to calibrate the
above meters

Answer / kiran kumar

Generally to calibrate any SMART flow transmitters, we need
to give direct ranges and fluid specifications through HART
Communicator. To check whether it is giving correct output,
we need to cross check the output of flow meter pipe should
be kept in a measured tank for a specified time and compare
the same with flow meter reading.
