WebCurrent meters measure the velocity of water at a point. The measurement of discharge in open channels requires the determination of mean velocity for each sampling vertical across the measuring section. A number of methods are in use to define the mean velocity in a vertical. Methods are usually defined by the number of measurements taken in ... Web• Other Methods There are other types of water level indicators and recorders – available on the market, such as weighted steel tape, chalked tape, sliding float method, air line pressure method and automatic recording methods. These methods are primarily used for closed systems or permanent monitoring wells.
