tunze wavebox in action

Good idea. Do you have any idea on how to do this? We just have some basic calculations from formulas that gave us the knowledge we have. The main problem is we don't have anyone with structural knowledge, Axel is trained as an environmental engineer specializing in sewage treatment and Claude is a retired electrical engineer for an aluminum manufacturer. Otherwise we have two machinists and an electrician. We don't really have anyone familiar with these sorts of structural tests.

Roger,
Interesting response but you seem to have taken my post's point wrongly or missed it completely. I was simply commenting on your reference made to surge buckets and how this designs wave action would cause similar, minimal stress loads. I would have to disagree with this assumption and feel you misrepresent your product in doing so. Of course, this is simply my opinion but I wanted to clarify this.
The comment I made about the tank life reduction was made in humor and I thought represented so with the
. Sorry if it came across otherwise.
Regards and keep the great products coming.

Well, yes, as a mechanical engineer I know how to do it...but that won't help you too much. Wanna send me a wavebox and tank?
Seriously, it's pretty easy to do and I think your engineers will love it. It's a very simple principle as the sensor just looks for a change in resistance as the sensor elongates (reducing its conductivity). The sensor is epoxied on the tank.
Here's a paper that should get them started:

And the same people (Omega) are a great source for equipment (at least in the US):

You'll spend some money and time to do it right, but in the end it should be well worth the effort.

Sorry Joseph, I didn't mean to seem defensive. I agree with what you said, but the truth is we don't exactly know. All I was trying to say was in my life I have seen crooked tanks, tanks on unlevel floors, poorly made stands, 30+ years old, left in a hot garage and they hold water. I also have seen new tanks unexplainedly blow a seal. That is the point, it is just so hard to say what caused it to fail and I still firmly believe a well made tank will not suffer from this device.
Thanks luvtolean. Tunze actually uses quite a few American made components and meters so it should be no problem to aquire these.

Roger, you said that the waves can be dialed down. I have a 360 gallon (96"x36"x24") and the overflows are 3 bulkheads on one end. The water level is about 2" from the top and it is an acrylic tank.
With what you know so far, will the Wave Box work if the waves are dialed down? I know from reading on the Wave Box I can get 2 wave cycles with an 8' tank. How small can the waves be and the Box still work?

RER- I don't know yet. It will "work" with a wave that is almost too small to be visible but whether or not that would be a useful flow is unlikely and I need to see just how low the waves can be and still provide a useful amount of flow. Both the 6212 and 7095 were sent to me last week, they are the only working final models of there type so when I get them I will be learning more, especially on the 7095 since I am writing the manual for it.

Ohhhh the 7095... I can't wait to get my hands on one of those.
Please keep us posted here over the next few months while you work/play with the 7095 & 6212.

The 7095 is really cool, the brightening and dimming LED for lunar cycle simulation is really perfect. I was really impressed with how that turned out. I also really like the new program for interval where the other pump just runs at minimum power and the LED power bar graph is really a nice touch too.

Roger,
will it be difficult to get a proper wave in a reef tank of 1000 litres if theres too much live rock? My tank is 2 meters in length and has a plexiglass shelf with rock above and below. Due to good growth of my SPS corals there's not much space left. I currently use both Turbelle 4002 and Streampumps and they make a good current.
Since the movie file from Interzoo '04 shows an open structure with no rock in front of the Wavebox, I am curious if it will work in my tank?
Sorry if my English is incorrect.

Gotta ask Roger.. what does the wavebox sound like? Is it loud?

Nah, as you probably know (better than I) given your "Occupation", there's better ways to do that such as measuring the change in curvature of the wafer.
Here's a couple of pics showing the type of application I'm most familiar with for them:
