Industries measure their discharges either to meet their NPDES permit or because of municipal / county requirement. For industrial operators charged with monitoring their process discharges, a Packaged Metering Manhole can be a cost effective solution to their flow measurement needs.
Factory integration ensures that the primary device is installed correctly and that the flows are properly conditioned to allow for accurate flow measurement and sampling. It also allows for a wider range of device styles and sizes to be integrated than can otherwise be readily accommodated in pre-cast construction.
Usually shipping as a single, watertight piece, a Packaged Metering Manhole requires only a minimum of line down time. Also, their lightweight nature - about 1/10th the weight of a pre-cast monitoring manhole - means that fewer personnel and lighter duty equipment are needed to complete and installation. These features make Packaged Metering Manholes the perfect choice for installation during holidays, weekends, or scheduled plant shutdowns.
Openchannelflow Packaged Metering Manholes have no seals to maintain, are corrosion resistant, and have a smooth interior surface that requires only a minimum of maintenance over their typical 25+ year lifetime. In contrast, pre-cast construction requires increasing maintenance over its lifetime.
When total cost of ownership is considered, Openchanelflow Packaged Metering Manholes are more economical and provide more accurate flow measurement than pre-cast solutions; making them ideal for harried plant or environmental compliance managers.
