Mechanical current meters are mostly based on counting the rotations of a propeller and are thus rotor current meters. A mid-20th-century realization is the Ekman current meter which drops balls into a container to count the number of rotations.
A velocity-type meter measures the velocity of flow through a meter of known internal capacity. The speed of the flow can then be converted into a volume of flow to determine the usage. There are several types of meters that measure water flow velocity, including jet meters (single-jet and multi-jet), turbine meters, propeller meters and mag ...
After having fabricated and testes several families of propellers, they found the best response in a dual propeller (two propellers fixed on an axle) sensor with two five-bladed, 30-degree pitch propellers with diameter of 22 cm. [1] The propellers are hard anodized, epoxy coated on the exterior, and protected by zinc anodes. They have been ...
Because they are used for domestic water measurement, piston meters, also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the UK and are used for almost all meter sizes up to and including 40 mm (1 + 1 ⁄ 2 in). The piston meter operates on the principle of a piston rotating within a ...
Using the Parshall flume flow equations and Tables 1-3, determine the flow type (free flow or submerged flow) and discharge for a 36-inch flume with an upstream depth, Ha of 1.5 ft and a downstream depth, H b of 1.4 ft. For reference of locations H a and H b, refer to Figure 1.
A marine thruster consists of a propeller or impeller which may be encased in some kind of tunnel or ducting that directs the flow of water to produce a resultant force intended to obtain movement in the desired direction or resist forces which would cause unwanted movement.
