A setter for a water meter comprises a pair of L-shaped pipes which are positioned in reversed relationship with their horizontal legs connected between a water supply line and a water distribution line. The horizontal legs are clamped in side by side relationship to vary the distance between the vertical legs. Adjustment of the clamp permits the setter to accept meters of different size. All joints are threaded thereby avoiding the use, of solder and the consequent danger of lead contamination.

Why it's free to use
- Filed June 24, 1992 and granted May 2, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 24, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 24, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
