FRP H Flume are very accurate for discharge management in open channel. Advantage of flume is wide opening at high flow to reduce backwater effect. Ni-Plast make H-Flumes are made in FRP with gauge marking at both wings of H-Flumes and show discharge in liter/second and water level in flume for free flow condition.

Application:

  • Laboratory, Institute, engineering and agriculture collages for demonstration and limited purpose for field irrigation

Range:

  • 15, 30, 60 & 150 liter/second. Big capacity H-Flume available on demand

Note: Electronic Recorder is available on demand for automatic discharge recording

FRP Replogle Flume OR Trapezodial Weirs are most accurate flumes and easy for installation. Due to vertical crest in downstream of flume above CBL, heavy scouvering and energy dissipation problems may come. Hence in India it is using only for laboratory and research institutes level. Ni-Plast Replogle Flumes are moulded, single piece FRP flume without joint. Gauge plate is molded and engraved for discharge and level measurements. Moulded arrow is given to understand flow direction and discharge table is attached with information of calibration formula, installation procedure and ready reckoner for discharge measurement.

Application:

  • Discharge measurement in small and big channels of irrigation and research Institutes.

 

Range:

 

  • 0.33, 0.5, 1, 2 and 3 cusecs capacity. Big capacity on demand

    FRP Standing Wave Flumes used for discharge measurement in channels and laboratories are experimentally investigated. Height and width of SWF are the two parameters characterizing the head-discharge relationship. Laboratory experiments are conducted by measuring the discharge and the head over the weir for variable weir heights and widths. Applicability of various formulations for the discharge coefficient are investigated.

    FRP V-Notches are useful for seepage measurement of irrigation dam and toe drains. Discharge in V-Notches can measure from 6 liter/second to 120 liter/second. In V-notch, advantage is of head over the crest is large and thus flow remains unaffected by surface tension and viscosity. Limitation of V-Notch is small discharge range and V-plate itself become obstruction to silt and hence not suitable for field channels in irrigation and for waste water management. Ni-Plast make V-Notches are manufacturing confirm to Indian Standard IS 9108:1979 and having molded and engraved gauge marking for measuring discharge in lit/second and level in centimeter. Provision can made on demand to remove V-Plate as and when require cleaning silt gathered in V-Notch.

    Application
    :

    • Seepage measurement of dam in foundation, inspection and top galleries and
    • Toe-drains. Limited use in waste water and laboratories

    Range:

    • 15, 30, 45, 60, 90 and 120 liter/second. (Above 120 lit/sec not recommended)

    Note: Electronic Recorder is available on demand for automatic discharge recording.

    We offer a wide range of premium quality V-Notch or Sharp Crested WeirsV-Notches or Sharp Crested Weirs are generally used for measuring small discharges like seepage from drains and gallery of masonry dam or toe drains. V-Notches can measure discharge from 1 lit/sec to 120 lit/sec maximum. For low discharges, V-Notches are superior to Flumes because head over the crest is large and thus flow remains unaffected by surface tension and viscosity. V-Notches have their own limitation and not suitable for discharge measurements in field channels due to obstruction of silt.

    The Indian Standards Institute (ISI) has drawn specifications for manufacture of V-Notches. Ni-Plast make V-Notches confirm to Indian Standards IS: 9108-1979.

    Mechanical and Electronic recorders are available with Ni-Plast V-Notches these enable automatic data recording of discharge measurements. Periodic discharge measurements at preset time intervals are logged in a data logger that is housed in the electronic recorder unit. The data logger can be connected to a desktop PC to download the data for further processing and generate reports like water seepage, water discharge during a given period of time, water accountability etc.

    Salient Features :
    • Ni-Plast V-Notches are made of prefabricated Fiberglass Reinforced Plastic.
    • They are most accurate in dimension & have an extremely smooth surface.
    • V-plate with upstream & down stream section is as per IS: 9108-1979.
    • 100 % anticorrosive, maintenance free and durable with a life of up to 50 years.
    • Engraved & moulded gauge marking shows discharge in cusecs & litres / sec.
    • Moulded and engraved discharge table with details of calibration & installation.
    • Readymade V-Notch structure very easy to install.
    • Automatic recorder for accurate discharge measurement & data recording.

    We are World largest manufacturer of fiberglass reinforced plastic (FRP) Cut Throat Flumes. Ni-Plast flumes are most accurate, molded flumes without any joint. Flume has engraved, molded and in - built gauge plate for discharge measurement in lit/second and cusecs. Any non-technical person or farmers can understand discharge easily. FRP is 100% anticorrosive material and having impact strength just like steel and completely maintenance free for years together. Moulded arrow is given to understand flow direction. Discharge table is attached with information of calibration formula, installation procedure and ready recknor for discharge.

    Application :- Discharge measurement in laboratory, research institutes, irrigation canal and waste water from factories

    Range of Cut Throat Flume - (One cusecs=28.32 lit/second=0.02832 cumecs)

    We supply a comprehensive range of Cut Throat Flume. Cut-Throat Flumes (CTF) are preferably recommended for field conditions for theirs simple design compared to other flumes. CTF is made up of two sections one converging & the other diverging. The throat section is avoided as suggested by the name ‘Cut-throat’ which indicates this special feature with a flat bottom surface and vertical walls. Discharge range measurable is from 0.33 cusecs (10 lit/sec) to 80 cusecs (2400 litter/sec.). Most suitable for field conditions because of the flat bottom, which avoids the silt obstruction problem and makes installation easy. Head loss is more and accuracy in results is 92%.
