#116869 - dirt cleaning or sound Responding to: ???'s previous message |
yes kai, you are right. may be regular cleaning would do the job.
and what about using sound instead. er.I meaning measuring the time of sound travels. I mean when through water, speed of sound becomes faster. this difference could be used to determine the water level. |
