For those instances where low flows require highly accurate measurement, TRACOM offers fiberglass weir boxes. Taking your specific flow rates and flow stream composition into consideration, one of our technical experts sizes each weir box to provide you with a product with the smallest footprint possible while covering the full range of your flows. Each weirbox is sized in accordance with ISO 1438/1-1990.
Each weir box comes complete with a fixed weir plate, fixed inlet baffle (adjustable baffles also available), inlet and discharge areas, and end connections (where required).
