4-20mA level sensor uses the robust industry standard current loop signal to represent the level . 

4-20mA is a Widley used industry standard for process measurement . 

Current Loop Level Sensor Overview

  • Supply 9 to 32vdc
  • Output : 2 wire current loop 4-20mA 
  • Accuracy 0.25% of full scale
  • Material Stainless Steel or Marine Bronze

4-20mA conversion

The current loop output is commonly converted into voltage.  These Guides and calculators demonstrate on how converting to voltage can be done with shunt resistors

4-20mA 1-5V Conversion Guide

4-20mA to Level Calculations Example 

for example a 4 to 20mA Level sensor with a range of 0-10mwg.
