Look for answers before you post. Check a search engine or
two to see if you can find the answer to your question or a collection
of useful links. If it's not, or if the answer is unclear, then that's a
pretty good justification for asking the question. This is not to
stifle questions, but you're less likely to be insulted if you have done
a little research ahead of time. (thanks Silas Marner)
Provide as much information as possible. The most frustrating questions on this site are like this: "I need a sensor to test water flow - which is the best one."
What are you testing for, what are you trying to determine? Is it in a
stream, a pipe, an aquifer? Are you looking to measure velocity or mass?
Are you testing for particulates, mineral concentration or pollution?
Is it wastewater, potable water, slurry, etc.? The more you let us know,
the better the chance that someone on the site will be able to help you
find an answer (thanks Silas Marner).
