This page contains links and descriptions of various instrumentation tools.

**4-20mA Signal Calculator**

This tool allows you to enter either a signal percentage or 4-20mA signal and it will output the corresponding percentage or 4-20mA signal. This tool

*Formulas*

Signal Percentage = ((Signal Value – 4) / 16) * 100

4-20mA Signal = 16 * (Signal Value / 100) + 4

**Square Root Flow Calculator**

This tool will calculate the linear and square root range for a transmitter.

*Formulas*

Square Root Value = ((Max Range – Min Range) * SQRT(Signal Value / 100)) + Min Range

Linear Value = ((Max Range – Min Range) * (Signal Value / 100)) + Min Range

**Vacuum Scale Calculator**

This tool will convert a vacuum measurement to three common ranges.
