Universal Water Current Meter is a world recognized instrument. This current meter is suspended in the water using a cable with sinking weight or wading rod and will accurately measure stream flow velocities 0.04 m/s up to 10 meters per second with multiple propellers. Magnetic the free ends of the proximity switch cable are connected to a Water Velocity Indicator. The calibration chart provided with the instruments. Universal Water Current Meter serves for determination of current velocities in water courses, canals, rivers and the sea. The Instrument case will be robust version made of Aluminum with locking arrangements. Velocity Measuring Range: 0.04 m/s ~ 10 m/s, Meter Body: Material high Quality non-corrosive Brass.
