Propeller Water Current Meter

The Propeller Type Water Current Meter is used to measure Velocity of water flow directly in m/s. The stainless-steel spindle carrying the cup wheel freely rotates in the bearing assembly. The magnet and reed switch assembly produces one pulse per rotation. The rotation of the Water Current Meter is sensed by sensor & gives pulsed output signal. As per IS: 3910-1966, the Water Current Meter employs a bucket wheel assembly that is mounted upon a shaft and rotates in response to fluid flow, generating a signal that is proportional to the fluid flow velocity. The current bucket wheel assembly is made of plated brass. It employs six hollow conical cups that are hand formed from sheet metal and individually soldered to a brass, star-shaped frame. The finished unit is then plated. The frame is shaped so that a strut connects the apex of each cup to the outer diameter of the following cup around the frame. The Propeller Type Water Current Meter can be suspended by means of a Fish weight while wading a stream, or by a cable and wading rod from an overhead structure. A tailpiece assembly assures proper alignment of the meter to water flow when suspended by a cable. Velocity is determined by counting the number of revolutions of the bucket wheel over a given period of time. Revolutions can be monitored by several means. The Digital Water Velocity Indicator / Logger (sold extra) by configuring the indicator with calibration equation (provided with each meter), it will result the direct current velocity of the stream in Meter per second. The meter is made from brass and stainless steel and all exposed surfaces are chrome plated for corrosion- free service. Each Current Meter is provided with a standard rating table to convert bucket revolutions to stream velocity in Metric units (meters per second), spare parts, instrument oil, cleaning cloth, screwdriver and a rugged carrying case.
