## User Guide

This flow transmitter 4 to 20 milliamp current output calculator provides a way to determine the output reading from the measured flow and flow transmitter range. A conversion scale graphic for each flow and 4-20mA current output range combination entered is also displayed below the calculated values.

### Formula

This flow transmitter output calculator uses the following formula to calculate the output over a 4-20mA range:

Linear mA out = 4 + (16 x ((Rdg – Low Limit) / (High Limit – Low Limit)))

### Parameters

#### Unit

Enter the unit used for measuring flow, e.g. m³/s, gpm, gallons per second, litres per minute, tons per hour, kilograms per day, etc…

#### Reading

This is the flow measured by the flow transmitter that you wish to convert to a 4 to 20 milliamp current output reading.

#### Low Limit

Enter the lowest flow that the flow transmitter will measure. For example zero would be a typical value for most flow transmitters, but you can also add negative (-) or positive (+) values as well. Please enter the value in the same flow units as specified for all other input values.

#### High Limit

Enter the maximum flow that the flow transmitter will measure.

#### Output Reading (mA)

This is the expected ideal flow transmitter current output signal in milliamps for the specified flow measurement.
