Procurement of Direct reading Water Current Meter with Depth analyzer

Supplying of Portable type direct reading digital water current meter with depth analyzer for river gauging, with necessary accessories and test certificate as per the following specifications. Portable Hand-held Direct Reading Current Meter: Portable hand-held device to carry along with the sensor which includes the battery inside. Facility to display both velocity and operational depth in its respective engineering units. Display: Digital display panel for Velocity, Revolution and depth of operation. Measurement type: All parameters are measured as direct reading in digital display unit. Automatic stabilization: The underwater probe should be hydro dynamically designed so that it has the facility to remain horizontally stabilized automatically, for eliminating Cosine Angle Error, caused by tilt of suspension cable. Arrangement for adding fish weight up to 25Kg. Additional fish weight is not the scope of supply Unit of Display: velocity in m/sec rounded to two decimal places, Depth of operation in meters rounded three decimal places and revolution at pre-settable intervals in seconds minimum up to 2 minutes Water current sensing method: Using Suitably designed rotor with non-conductive reed switch/ inductive signal pick up. Range of velocity: 0 to 5m/sec, with an accuracy of 0+/- 1% Depth of operation: 0 to 12 m with an accuracy of +/- 5mm. Application: Suitable for both fresh and saline water applications. Power: Rechargeable battery with Battery charger. Cable length: minimum 30m with provision for extension on demand. Material: Non corrosive, Stainless steel Carry case: Suitable for easy transportation of the equipment. Sensor handling rope: Nylon rope 25m. Sensor : IP 68 category Memory: Non-volatile memory in the form of SD card or USB thumb drive of suitable capacity to store at least one year data at the rate of at least 10 sets a day (a set of data comprises depth of operation, velocity, revolution). Guarantee: 1 year Comprehensive Warranty. Test Certificate: Velocity Calibration/Test Certificate to be produced from a recognized institution (CWPRS, KRS etc.) according to their testing facility. Training: Vendor needs to provide minimum 1day training in operation, data collection, and maintenance of the equipment to the staff at the delivery point with User manual. Service requirements: Service and spare parts availability must be ensured for at least a period of 5 years.
