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.
