Head loss, a dirty filter and a throttled valve mean the number on the pump box is never the number in the pipe. This paddle-wheel meter reads live \u003cb\u003eGPM or LPM\u003c\/b\u003e and keeps a \u003cb\u003erunning total\u003c\/b\u003e, so you can see exactly what the pond is turning over and watch the flow drop as the filter loads up (a genuinely useful backwash cue).
