FRP Parshall Flumes

FRP Parshalll Flume We are World largest manufacturer of Parshall flumes, and manufacturing up to 3300 cusecs capacity. Ni-Plast Parshall flumes are molded flumes and available in assemble-dissemble system for easy and economical transportation and installation. Molded and engraved gauge plate is given to show water level in flume and discharge in liter/second and cusecs. Ni-Plast Parshall flumes are manufacturing confirm to Indian standard IS 14371:1996 and using high quality grade resins and glass fibers to sustain tremendous load of flowing water and their high velocity. Parshall flume discharge measurement system is supported with “Electronic Discharge Measuring Recorders” for 24x365 days for automatic data recording.
Application :- Research institutes, laboratories, irrigation small and big canals and waste water from factories
