Type of flowmeter for large water pipe
Type of flowmeter for large water pipe
(OP)
Would anyone have a recomendation for the type or perhaps even a brand of flowmeter to install in a particular applicaiton? The pipe is 20" and 30" steel pipe pumping water at a rate of 2000-5000 GPM. The site happens to be fairly remote. Power is available, but no buildings. I am a little bit familiar with how magnetic flowmeters work, but have never installed one or sized one up for a particular application. Would this type of meter be a good choice? Would a nonconductive section of pipe have to be spliced in to make it work? Maybe there are cheaper options. I'm just looking for a starting point or any helpful pointers. Thanks!

Ultrasonic works well. The clamp-on type are really good if you need to service or replace. Dependin on accuracy required of course.

Check with Fischer Rosemount. I saw Annubars working even for custody transfer application.

You could try Peek (now under Thermo electron?) who even provide mag meter solutions for open channel (river) flow measurements or an insertion turbine or vortex... try your seach with "insertion" and you get a large range of manufacturers to sort through looking for one that does your size... typically in the $1500 to $3000 price range.

Is "wedge meter" the same as vortex shedding meter?
Good luck,

RE: Type of flowmeter for large water pipe
No. Vortex shedding meter is a vortex shedding meter.
A wedge meter is a DP meter. Instead of a orifice, for example, there is a literal "wedge" or simiilar engineered constriction in the pipe. This also creates a pressure drop, though not as much of one as an orifcie. Hence, usually used in larger flowrates. The wedge is usually only on one side of the pipe.
Here are links with good schematics:

In other words, there are lots of options and it now depends on finding the balance of features/costs/benefits.

Clamp on ultrasonic is immune to what is inside the pipe. If you cover the outside with a box, it is well protected.
A DP with diaphram seals is also good to protect against stuff getting clogged, from junk in the fluid.
