Question - Where we you use square root extractors?
Answer -
Square root extractors are used across Orifice and other DP transmitters.
The relationship between the differential pressure (^P) and flow rate (Q) are not equal. DP is proportional to the square of the flow rate Q.
To convert the signal from the flow transmitter to one directly proportional to the flow rate, the square root of the signal from the flow transmitter must be obtained or extracted.
