## User Guide

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

### Formula

This liquid level 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 liquid level, e.g. bar, psi, kPa, inH2O etc…

#### Reading

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

#### Low Limit

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

#### High Limit

Enter the maximum level that the liquid level transmitter will measure.

#### Output Reading (mA)

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