Current meter rating tank facility

The major components for calibration of water current meters are the straight open Rating Tank of uniform cross section and an electrically driven Rating Trolley. The Rating Tank & Rating Trolley was established in 1955 for testing of ship models as well as calibration of current meters. The tank is 228m long, 3.66m wide and 2.13m deep. The Rating Trolley run on two parallel rails accurately aligned. The overhead shrouded bus bar power supply, the servo drive controls the AC servomotor with Programmable Logic Controller (PLC) for precise speed control in the speed range of 0.01m/s to 7.5 m/s on-board and remotely operated real time data acquisition and processing system using specially developed software with Supervisory Control and Data Acquisition (SCADA) and Human Machine Interface (HMI).

Drag force measurement facility

Drag force measurement facility with load cell & real time data acquisition system is available on the Rating Trolley for various shape, size of floating & submerge water bodies at several different conditions viz. depth of submergence, angle, add on load etc.

Coastal Bathymetry Survey System

Coastal Bathymetry Survey Systems consisting of Single beam dual frequency Echo sounder, Global Navigation Satellite System, Heave Sensor, Data Acquisition & Processing System, Hydrographic Survey Software to measure sea depths & to plot depth contours.

Automatic Weather Stations

Automatic Weather Stations installed at Satpati near Palghar, Maharashtra & Nani Danti near Valsad, Gujarat for real time measurement of weather parameters viz., Barometric Pressure, Air Temperature, Relative Humidity, Wind Speed, Wind Direction, Rain Fall & reception at AWS Server in the CWPRS, for weather & climate condition monitoring.
