The flow calibration factor format consists of 10 characters, including two decimal points. An example flow calibration factor for a Micro Motion ELITE sensor would be: 4.27454.75

The components of the flow calibration factor are:

• The first five digits (4.2745) are the proportionality constant.

• Each sensor has a unique calibration factor.

• This calibration factor, multiplied by a Delta-T measured in micro seconds, yields mass flow rate in grams/sec. 

• This mass flow rate is then converted into the desired units by the transmitter.

Example:
Given 5 microseconds Delta-T
5 X 4.2745 = 21.3725 grams/sec flow rate

• The last three digits (4.75) are a temperature coefficient for the sensor tube material.

• This coefficient compensates for the effect of temperature on tube stiffness.

• It is expressed in terms of a percent change in the proportionality constant per 100°C.
