Converting Liquid Level Units to Sensor Output Signal Units
Liquid level units are converted to sensor output signal units by first converting the liquid level units to
pressure units and then converting the pressure units to sensor output signal units. The calculation is
useful in troubleshooting and allows us to determine if the pressure sensor is providing the correct output.
Using two previously investigated relationships we arrive with the following formula:
Measured Output Signal (Sensitivity x Level x SG x k)+Minimum Output Signal Value
Manipulating the formula and you can determine Level:
Level = (Measured Output Signal-Minimum Output Signal) divided by (Sensitivity x SG x k)
1. Calculate the current output signal from a pressure-type sensor that has a 0-2psi input signal
range if it measures a water level of 0-53m, the sensor is supporting a 4-20mA output range
