Best use I have seen of organic matter (Polite eh?) is heat reclamation. Farmer had a big compost/manure pile and he ran cheap plastic pipe through the middle and circulated water. The rotting organics put out heat, circulating water picked up the heat and he used the hot water for heating a...

and your pumping what?? The weight of the fluid you are pumping is required.

What about a mechanical system? Perry's handbook has an illustration of tape float gauges. (section 22) Float in the tank, calibrated gauge board on the outsideside. Float is attached by a wire, chain, tape, over a sheave to an indicator on the outside. As the float rises, the indicator...

To the same standard as the flanges you are sandwiching it between.

Not sure if a company called Pyroban operate in the US try looking them up. They retrofit and produce conversion kits for trucks to the new European ATEX Directives(explosive atmospheres)

I see a lot of Flow straighteners on Fiscal metering/ custody transfer stations. You might want to try some of the metering companies such as Daniels or Rhomax.

Just on the Wet bulb with PLC output. Your looking for a dewpoint meter/analyser, yes they are available.

I can only comment on ball valves. Hole faces upstream. Theory being that if it is facing upstream the pressure acts on the inside of the ball and will increase sealing forces. Other way round tends to lead to more leaks (in our experience)

There is an ABEC classification for bearings. ABEC 1, ABEC 3, ABEC 5. I think this just governs the tolerances that the bearings are built to rather than the type. Ask a kid on rollerblades or on a skateboard! They know all about the bearings in their skates and their classifications!

I might be a cynic but is non taxed diesel died yellow in your country? Ours is red!

I don't think the flowrate is criticial. What you need is a positive pressure. A slight positive nitrogen pressure will prevent the ingress of O2. Your flowrate will be driven by the total leakage from your system. Usually controlled by a regulator or self regulating PCV.

I doubt you will find one that small. The size of the pump jack is related to the stroke of the downhole pump.

sounds like an off the shelf jetting/jet wash/pressure wash package. Sounds silly but if you are looking for portability, try your local hardware store, most will be electric so couple it with a portable generator

you do have the d/s side of the ball drilled don't ya?

Ahhh the one missing part! SHould have been able to work that one out!
