If the manufacturer tells you to use 10 to 30 V to power the sensor, it is not a good idea to use 9 V.
Also, 9 V block batteries are for smoke detectors and won't power an Arduino for more than a few minutes.
Using sensors and Arduinos "off the grid" requires an entirely different approach than disposable batteries, unless you are willing to travel out to change them every few days.
You will probably need a solar panel, a charge controller and a rechargeable battery (lead acid is great) for your system.
