How to have a Flow Sensor with a Non-Linear Reversed Output Application Note

Problem:

Have a flow sensor with a non-linear reversed output. Create a 4-20mA output proportional to flow rate.

Solution:

The 811T offers a 25 break-point table for sensor linearization. Input percentage is based on sensor V DC output.
Output percentage is based on actual flow rate. “Reverse” action is also achieved via the table.
