A Volumetric Calibrated Weir is the most practical, economical instrument for testing new sewer lines - night flow studies of existing lines - free flow from open end pipe.
The volumetric weir is basically a compound weir that incorporates the advantage of a 90° V-notch for measuring small infiltration flow where accuracy is of prime importance. The V-notch section measures from 57 gallons to 3700 gallons per 24 hours, which is the range of normal Acceptance Test Requirements. The rectangular section of the weir is capable of measuring in gallons per day up to 35% of pipe capacity.
Rugged Construction and noncorroding materials make the volumetric weir extremely reliable. There are no loose parts that require assembly. Installation is quick and the weir requires a minimum of care.
EASY TO READ FLOW RATE - Simply check water level at the face plate. The figure above the line matching the water level gives you the rate of flow in GALLONS PER 24 HOURS (METRIC WEIRS-CUBIC METERS PER HOUR).
Especially designed for use with Bubbler Flow Meters, all Volumetric Weirs are now available with an attached "Bubbler Tube".
