Frequently Asked Questions
Everything you need to know about the OraRV Tank Level Sensor.
The OraRV sensor uses ultrasonic technology to measure the distance from the sensor to the liquid surface inside your tank. It mounts on the outside bottom of your tank — no drilling or modification required. The sensor sends a sound pulse through the tank wall and measures the echo to determine the liquid level with ±2% accuracy.
The OraRV sensor works with polyethylene (PE), ABS, and fiberglass tanks commonly found in RVs. It's compatible with fresh water, grey water, and black water tanks up to 24 inches (60cm) deep.
Installation takes about 5 minutes per tank. Clean the bottom of your tank surface, peel the adhesive backing on the mounting pad, and press the sensor firmly in place. No tools, drilling, or plumbing modifications needed. The included mounting template helps you find the optimal position.
