Tool to calculate Span and Input/Output relation of an Instrument Transmitter Using LRV and URVURV

Instrument Transmitter Span and Input/Output relation Calculator
This tool is used to calculate the Input and output relation from LRV and URV. How to use this tool?

You need the following information to calculate the Span and Input/Output relation.
 LRV - Low Range Value.
URV - Upper Range Value.

What is LRV?

LRV stands for Low Range Value.    
Let us take a Level transmitter as an example. LRV is the value shown by the transmitter when the level of the tank is zero and at this state the transmitter will give a 4 ma output.

What is URV?

URV stands for low range value. URV is the value show by the transmitter when the level of the tank is 100 % and at this state the transmitter will give a 20 ma output.

What is Span ?

Span is the algebraic difference between URV and LRV.

Span = URV - LRV.
