Thanks from Brazil
sir i really thankful for such a good explanation so for
Thanks for sharing and please upload another video to calibrate it...
This product does not have a calibration option.
Sir thank you for the video. I want ask about how to using the average of velocity in this equipment?
hello a question, I would like to know how is elice's right?
How about for open channel sir, Is there any method or approach to measure flow? The open channel is trapezoidal with possible sedimentation.
Thank you and God Bless.
This is slightly more difficult. You must calculate the area of the channel that has water in it, there are formulas to do this published on many websites. Search for area of a trapezoid. The flow probe use is basically the same, however, remember that this technique is an estimate of flow, not an exact measurement. Sometimes you must make your best estimate with the tools and situation that you are dealt.
Is there any effect of depth to measure velocity of water by global water flow?
Yes, the depth has an effect on velocity.
www.inmtn.com - we have many options for monitoring flow in rivers, streams, canals and pipes.
Battery life is good(this one ran roughly a decade) but when it fails sending the thing in for service to replace the battery is over 1/3 of the cost of a new one. Currently they have a supply shortage and service is impossible. So we replaced the battery instead. The split location is the seam line around head. This one has a short interior flange that sticks down from display side inside the lower half with a bead of sealant around the bottom edge. Because I went looking for tabs to unlatch and there were none I cut part of the flange off while getting this one apart. There are no tabs and no alignment notches in this one so 2 potential strategies to try getting it apart. A really strong twisting motion might separate the cases by breaking the sealant. Alternately I would try gently flexing the plastic of the display side in with a pair of slip pliers to break the sealant in localized locations. Repeat till worked far enough around to get the sealant loose. The halves separate and 4 screws hold the display to the case house. Be sure the meter is face down while you do this as there are 4 tiny metal pins that extend exterior buttons to the interior buttons that are incredibly easy to lose. If face down they will stay in their plastic holders. The battery in this one was a solder in that any good electronics person should be able to change with a battery cost of a few bucks(vs over $450 to service it)(freight will cost you far more than the battery) The battery in this one was CR-2354/HFN. Since we needed it fast we subbed with a CR2450 because they are commonly available here and only 10 mA lower max draw. 560 mA max draw orginal vs 550 mA max draw for the 2450. We fudged a holder together with epoxy and edges of a windshield wiper blade that will work for now.
