I've thought about putting a sender there as well, but I'm guessing you'd
see some lag and it'll read somewhat low. Since the transducer won't
actually be in the water flowing through the block, the heat will have to
be conducted out along the stagnant water in the pipe, and there might be
some losses due to conduction from the pipe to the air. I can't say how
much the error will be though, so I'm not sure if it would be significant.
