The VFD's parameters (if they're not locked out entirely) will be set through pushbutton interfaces on the VFD itself. None of the signals coming in to the VFD can modify its parameters.
The main ingredient in ketchup may be tomatoes, but they're pretty much overpowered by HFCS. There are plenty of kinds of barbecue sauce; you just have to find one that's good.
At least in catsup, the main ingredient is tomatoes. In pretty much every barbecue sauce I've seen, they are vinegar and maize syrup (or if lucky, treacle or sugar).
What planet have you been living on? That's precisely what ketchup is: tomatoes, vinegar, sugar, and salt. At least barbecue sauce is usually a little spicy.
Not true; they can mess with the disinfecting chemicals.
Most of the disinfection chemicals do exactly that: disinfect. They have very little effect on taste or odor problems. Chemicals such as powdered activated carbon or potassium permanganate can be added to try to combat undesirable tastes, odors, and colors in the water, but they're costly and not terribly effective. Since controlling taste, odor, and color are all secondary standards according to the EPA, water treatment processes don't typically spend too much money trying to perfect the taste of their water. As I said, this isn't new; GGP is just used to the flavor of bottled water now.
Philadelphia, for instance, adds enough chlorine that the tap water burns your throat going down.
I very much doubt it. The EPA regulates chlorine residuals in drinking water. Adding too much chlorine would be expensive and serve little useful purpose in addition to making the water unpalatable; additionally, if free chlorine is used, it can create harmful disinfection by-products. 2-4 PPM chlorine is typical for a disinfection residual. A quick internet search didn't provide any information about high levels of chlorine in Philadelphia's drinking water.
Other municipalities use chloramines rather than straight chlorine, which produces a different taste.
Free chlorine tastes like chlorine; water treated with chloramines doesn't taste like chlorine. I am well familiar with this fact. However, the quality of water produced by one municipality wouldn't vary based on chlorination/chloramination unless it switched from one to the other, and municipalities don't change their treatment process that often. The taste of water between different municipalities will vary, but that's to be expected.
The requirement is that all foods and drinks have a nutrition label. Why is this hard to understand? Is water not a food or drink? Is bottled water not intended for human consumption? Oh, it is? Well then, it NEEDS A NUTRITION LABEL.
I've yet to visit a municipality where the taste hasn't declined *significantly* since the advent of bottled water
Not true. You've just gotten used to the flavor of bottled water.
There is, in fact, very little a municipality can do about the flavor of their water. Essentially the only way to control that is by membrane filtration (reverse osmosis), which is prohibitively expensive on a large scale.
Take a vfd and crank up the carrier frequency and most motors begin to have problems.
You can't do that remotely. You'd have to have physical access to the pump's VFD.
Your SCADA system will send a command to a PLC which will typically send a 4-20 mA analog output to set the speed of the pump, and probably also have relay outputs to send start/stop signals. Everything else is handled by the VFD. You basically get "start", "stop", and "how fast". Like Lumpy said, you can't tell it to do anything weird.
Furthermore, the VFD should have interlocks that will shut off the pump on over-temperature / over-vibration / over-current, and there will usually be more software interlocks in the PLC's programming that will command the VFD to shut off the pump if, for instance, it's running and the flowmeter isn't showing any flow, or if a valve goes shut on the effluent side of the pump.
Water pumps don't normally affect water pressure. They pump water to the top of a water tower for storage until gravity pushes it out.
That is not how they "normally" work. It is only one way that a water system can be designed to work. It can also be designed with pumps that pump directly into the system.
Most water systems of any decent size have a combination of both elevated storage and pumps. Some parts of the water system's distribution are may be pressurized by elevated storage tanks, while other parts of the distribution area are pressurized by pumps.
Can someone please explain the trick to me? Is he picking the right card, or a card that looks like the right card? I mean, if you showed me six cards and I pick one and then you show me a different six cards, I'm going to remember what my card looked like, unless all twelve cards are very similar.
The trick is that the magician, without ever knowing which card you picked, seems to have "magically" taken it out and replaced it with a different card. It relies on the fact that you won't remember the 5 cards you didn't pick, or else you'd notice that all of them were replaced.
However, the point of this study was determining whether you unconsciously did remember which cards were in the first set, even though you could only consciously remember the one you had chosen.
Wow, that was weird. As soon as I came to "lvier nda" I completely restarted under the assumption that you'd intentionally scrambled the letters of the words around. I didn't notice that "lvier" and "nda" were the only misspelled words in the whole thing until I'd read the entire comment. And strangely enough, it made the entire thing somewhat difficult to read.
You don't have to actually taste it to have a pretty good idea whether it's good. Generally speaking, vegetarian animals (like cows) are tasty, carnivorous animals (like cats) are not tasty, and omnivorous animals (like people) are really tasty.

I think you got your osmosis effect backward.
FWIW, that works for water disinfected with free chlorine (the kind you can taste, which GP complained about). It doesn't work for chloramines.
You've probably gotten used to the flavor of filtered water, then.
If you ever get a chance to try Gates barbecue sauce, I recommend it. I believe they ship worldwide from their website.

Sugar, HFCS... regardless, it's still sugared tomato paste with vinegar in it.

Ketchup is disgusting. It's a poor substitute for barbecue sauce... a very poor substitute.
If you add enough sugar to it, yeah, anything is sweet. Including rhubarb.

If that made any sense, caffeinated beverages would be classified as drugs too.

Beer must not be intended for human consumption.

I haven't seen any rouge or unauthorized dehumidifiers running
What does their color have to do with it?

Yeah, well, of course. How many fish do you know of named Bob?
No Bobs, but I know of A Fish Called Wanda.

He has probably never gone fishing and used bait like corn, hot dogs, bread, gummy worms, or french fries.
One of those things is not like the others...
By his second sentence I knew what it said already and that undoubtedly influenced my ability to read it.
Fishes are pretty carnivorous.
Pretty sure most are omnivorous. They're like goats or chickens... if it looks anything remotely like food, they eat it.
Pigs are omnivores too
I already said that.
You don't have to actually taste it to have a pretty good idea whether it's good. Generally speaking, vegetarian animals (like cows) are tasty, carnivorous animals (like cats) are not tasty, and omnivorous animals (like people) are really tasty.
Did I say people? I meant dogs. Or pigs.
