The illustration on the right is an example of "hard to reach places" it shows the sensor mounted into a T-element on a pipe. The sonic wave generated by the HE660 is guided through flexible tubing to the water source underground. The level variations of the water source can be determined precisely.
The figure on the right illustrates use of a wave guide. The sonic wave generated by the HE660 is guided to the D1/D2 surface. Distance D1 is measured precisely. There are advantages to this setup; outside disturbance cannot effect the D1 distance measurement.
The illustration to the right, shows a sensor mounted into a T pipe element, which is mounted on an overhead pipe. It is also possible to mount the sensor and the processing unit on the mobile silo.
On the right, no extension is used, this setup is vulnerable to interfering objects; but the level is measured as precisely as by the setup above.
