Introduction

 

This solution is an Ijinus product grouping water height measurement by aerial ultrasonic, 

with automatic measurement cycle changes depending on thresholds, flow rate 

transformation through conversion tables. Some sensors are equipped with connectors 

for coupling with an overflow detector or to control water sampler.  

In addition to measuring, these sensors can also be paired with others or serve as data 

concentrators (for version with communication 3g or Sigfox). 

 

 

 

 

2.

 

Three main ranges of measurements (depending on max distance to measure) 
 

LNU06V3 & LNU06V3-EX

 

Measure up to 6m 

 

 

        

 

LOG10V3

 

Measure up to 10m 

External ultrasonic 

probe
