• Digested outlet slurry is an excellent organic fertilizer.
• Bio-gas plants can install in small space even on terrace or balcony.
• Bio-gas plant help for better environment, keep house & city clean.
• Return on Investment (ROI) of bio-gas plant is hardly one or two years.

Orifice Meter is using at laboratory and research level for discharge measurement. Orifice meter are practically abounded due to considerable fall, excessive loss of head and silt deposition in upstream side. Ni-Plast make orifice meters are made of FRP and having 50 mm to 120mm orifice. Discharge range is from 15 liter/second to 100 liter/ second. Gauge marking in centimeter and liter/ second is given on orifice plate. Discharge table is given with calibration formula for free flow condition.

FRP V-Notches are useful for seapage measurement of irrigation dam and toe drains. Discharge in V-Notches can measure from 6 lit/second to 120 liter/second. In V-notch, advantage is of head over the crest is large and thus flow remains un-affected 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.

Replogle flumes 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.

Standing wave Flumes are commonly using for discharge measurements in extremely large capacity canals. Advantages of SWF are comparatively lesser head loss than all other flumes. But difficult to construct for maintaining dimensions and slopes in downstream side. Most of SWF are failed due to limitation of construction. Standard design sections like other flumes are not available for SWF. Ni-Plast make Standing Wave Flumes are available only for laboratory purpose. Gauge marking, discharge table, arrow for flow direction are available.

H-Flume are very accurate for discharge measurement in open channel. Advantage of H-Flume is wide opening at high flows to reduce backwater effect. Due to complicated geometry, it is not much popular in India. Ni-Plast make H-Flumes are made in FRP with gauge marking at both wings of H-Flumes and shows discharges in liter/second and water level in flume for free flow condition. Moulded arrow is given to understand flow direction. Discharge table is attached with information of calibration formula, installation procedure and ready recknor.

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.

1. Laboratory level: 0.33, 0.5, 1 and 2 cusecs.
2. Irrigation & waste water: 5, 10, 20, 30, 50, 80, 100, 150, 200, 300, 400, 500, 750, 1000, 1500, 2000, 2500 & 3300 cusecs.

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.

1. 20x90 & 30x90 section - 0.33, 0.5, 1, 2, 3 and 4 cusecs.
2. 40x180 & 60x180 section - 5, 6, 8, 10, 12, 15, 18 and 20 cusecs.
3. 60x270 & 100x270 section 25, 30, 35, 40, 50, 60, 70 and 80 cusecs

Object of DL meter is to measure and record any relative change in water level of reservoir. DL- meter is installing at the top of the reservoir and float is keeping in closed pipe chamber on reservoir wall. Rising or falling down water level in closed chamber is relatively transforming to float mechanism and same get electronically sense to store in hardware unit. Same data then transmits to flood cell for processing to software for analysis by GSM modem technology. We have installed such recorders successfully to prestigious projects in India like Narmada, Ukai, Ujjani dams.

Sometime authority has to measure discharge in canal but construction of flume or HR gate provision may not be possible. In such circumstances, we have developed discharge recorder based on Mannigs formula. We are installing DL-Meter in the chamber of open channel to measure level in canal. Hydraulic data of canal geometry has to feed in software to measure discharge. Same data then transmits to central station to process in software and analysis. This system is very useful for main canals and waste water channels in factories.

Very big capacity canals are running 365 days and construction of flumes is not possible. We have developed unique recorder to measure and record discharge of canal based on bearnullis equation. In upstream and downstream of HR gate two DL Meters are installed to measure water level difference. Third recorder is installed to measure gate opening position. All these data from recorders sent to server for discharge measurement. Same data then sent to flood cell office to process in software and analysis. We have installed such recorders in Gujarat state.

Ni-Plast make FRP gauge plates are very popular in India and installed on most of the dams in Maharashtra & Gujarat states for reservoir level measurements.

Special features of our gauge plate.

• Very sturdy, both side finish and sandwich with M.S. strip
• Bands & figures are moulded and engraved, hence very accurate.
• Reduced level (RL), FRL, MWL can engraved on gauge plate.
• 100% anticorrosive when deeped in water and hence lifelong.
• Installation on fabrication frame or in power fastener on dam wall.
• Custom made for specific requirement can manufacture for large quantity.

Object of DQ-Meter is to measure and record relative change in water level in flumes and discharge. Chamber is constructed behind flumes. DQ Meter is installing at the top of Chamber. Rising or falling down water level of float kept in chamber sense electronically to store level & discharge of flume in hardware. Same data then transmits to authority to process in software for analysis by memory card or by GSM modem technology. We have installed such recorders to different irrigation projects and waste water management in factories.
