This mount is used to install your untrasonic sensor horizontal in your watertank to measure the verticaldistance to the watersurface. Mounting the sensor vertical (pointing downwards) makes it prone to misreadings due to condensation. This mount has the sensor horizontal, with a 45° surface that reflects the ultrasonic waves and prevents droplets from forming on the sensor.

1 cable-tie secures both the mount and the sensor to the hose/pipe entering the tank. If you need different mounting options let me know, i'll try and edit the model to suit your needs.

I'll add more links to the tutorials in a few days.
