1. IIntroduction
Some Ijinus loggers are equipped with a 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 2G, 3G, LTE or NB-IoT).
2.
Three main ranges of measurements (depending on max distance to measure)
LNU06V4
Measure up to 6m
LNU10V4
Measure up to 10m
LOG10V4
Measure up to 10m
external ultrasonic
sensor
For example, the figure below shows the indication of the diameter of the area that will
be studied the ultrasonic sensor according to the distance:
Distance between the sensor and the water (m)
