Visit to other Live Installation sites by VJNL team in addition to the inspection of equipments: 2.1 In addition, several Live Installations sites were visited by the VJNL team to understand and verify the actual working of Telemetry systems in the rivers and canals in-situ which includes the sites: River ENZ in Baden Württemberg / Black Forest Area / Calmbach / Neuenburg / Pforzheim, River AARE Aareschlucht or Gorge (enroute to Interlaken from Luceren) River Aare connecting Brienzensee&Thunersee lakes near Interlaken City River Aare flowing in the heart of Bern city. Munich City Drinking Water Supply Schemeprovided with SCADA monitoring wherein raw water (ie., pure which does not require any treatment) is being supplied from Artisan wells which are recharged under glaciers of Alps (mountain series) Luceren City Drinking Water Supply Scheme (EWL) which integrates sourcing of water from lake, ground & spring at the ration of 50 : 32 : 18 2.2 A Bigger manufacturing facility of HydroVision Parent Company GWF in Lucerne, Switzerland was visited to know the systems and processes of manufacturing, testing and endurance of the flow meter instruments. 3. Date wise visits undertaken in Germany 3.1 On 27th April 2018 – Friday Evening we reached Munich(Germany) by Etihad Airlines. We met the Managing Director of Hydrovision GmbH, Kaufbeuren in Germany and had introductory dialogue and background familiarisation among each of us after arriving at Kaufbeuren. 3.2 Dr.JuergenSkripalle – A Civil Engineer and Masters in Water engineering, with Doctorate in Fluid Mechanics (Computation Fluid Dynamics). A very passionate person about the flow dynamics and Hydrology, he is surrounded by equally competent colleagues at Hydrovision GmbH. 2 Photo taken at Irsee in the Evening for Coffee, close to HydroVision GmbH Factory 28thSaturday(A Visit to HydroVision GmbH for Half Day) / 29th Sunday – Holiday. 4. Visit to Hydro Vision, GmbH, Kaufbeuren and presentation by MD, Hydro Vision Mr Dr. Juergen Skripalle On 30th April 2018 Monday – We visited HydroVision GmbH Factory and office. Visit to Hydro Vision, GmbH, Kaufbeuren 3 4.1 Introduction of the Company HydroVision GmbH and the various products that are manufactured at the factory was introduced by Dr. Juergen Skripalle, Managing Director of HydroVision. He started it in 2002. He was in to flow meters back from 1992 when he got his Masters in Hydrology. He also elaborated on the various type of project and installation carried out for Open Channels, Large Rivers, Penstock pipes, water supply pipes using technology involving Ultrasonic, Radar, Optical type, and installation methods involving both non contact type and contact types.Hydrovision showed us their installation pictures of various flow meter in Rivers as wide as 950 meters and pipes of 6-7 meters diameters using Ultrasonic transit Time technology. They also showed the use of gated Doppler ultrasonic flow meters for small channels and small pipes. 4.2 VJNL, Managing Director, Shri K Jaiprakash presented the Master plan of the scheme, current status of progress on lift component of Yettinahole along with the need for expediting the implementation of Telemetry for the same as the Nigam is committed to commission the lift component shortly. Further he explained that this Telemetry would facilitate assessment of yield besides ensuring measuring of minimum flows on to the downstream side to meet the ecological needs which is mandatory as per stipulations laid down by the MoEF, GOI while according Stage-2 forest clearance so also one of the compliance to the directions of NGT which the Nigam has to abide by. He also emphasized the need for undertaking studies to have a holistic approach on the project in its entirety with regard to the adoption of Telemetry in future. Briefing by Dr. JuergenSkripalle about the introduction of the Company and various products being manufactured at the factory 4 Secretary WRD during deliberation emphasized the need for integrated sustainable measuring device and in-house capacity building & MD VJNL emphasized the need for expediting the implementation of Telemetry for the lift component of Yettinahole (the present task assigned to M/s Canarys Automation Pvt. Ltd.) in the light of directions of NGT & stipulations by MoEF, GOI Briefing by MD VJNL as how the discharges in the canals are being assessed using current meters and Empirical formulas, shortcomings to that effect and the need for fool proof mechanism like Telemetry for assessing the flow 5 Presentation by MD VJNL on the profile of lift component of Yettinahole along with the status of progress and the need for expediting Telemetry installation for assessing the yield being the primary requirement and also in the light of stipulations issued by MoEF, GOI and directions issued by NGT 4.3 During deliberations, the Secretary WRD emphasized the need to have integrated sustainable measuring devices which will give inflow, discharge and delivery details in Real time data transmission, the necessity of maintaining the system and the provision to have in-house capacity building to sustain this system. 5. Visit to the equipments lab at Kaufberen and inspection of equipments being procured: Visited the factory, conducted Product Checks and Inspection of the materials to be shipped to the Yettinahole project site. 5.1 Hydrovision Engineers, Peter Kruger and Dr.Skripalle representing Hydrovision showed us the different units of the factory, the concept and working mechanism of the flow meters were explained. All the flow meters are based on Ultrasonic sensors, Radar Sensors and Optical Sensors, which measure the velocity of the water and then the same is processed in electronic micro controllers which give the velocity of the particle movement in the medium, then the mean velocity in the entire cross section of the gauging site. By measuring the water level continuously, the area of the cross- section of gauging site is known, then using Continuity Equation, the discharge is calculated. All this takes place in the Flow Meter Transmitter/Electronics, which is connected by signal cables to the sensors. This measurement is a continuous process, 24x7, which provides the measurements and the data is locally logged. The logged data is periodically transmitted through Telemetric GSM/GPRS modem which is built into the system. 5.2 VJNL has ordered for 3 Nos. Optical Type Flow meters, 6 nos. Non-contact Radar flow meters with Non-contact Radar water level transmitter, 1 No. Kanalis Transit Time flow meter and 1 Nos.ADCP which were kept ready for shipment. 5.3 All the flow meters are manufactured as per the order, arranged on a rack and were ready for dispatch. They were all accompanied by the Test certificates after tests in the factory test rig. The team of officers inspected the same. 6 5.4 Every component was checked for the serial numbers and the same were noted, the packaging was overseen. 5.5 Every flow meter is tested in the Factory test rig against a Standard Meter. The supplied Master meter(Aquaprofiler M-Pro 1 Nos) is also tested against the standard meter and shall be used in Yettinaholeproject site to cross verify every Installed flow meter across the streams. The test certificates will accompany the flow meters.
