Tiivikvoolumõõtjaid

Tiivikvoolumõõtjaid, also known as vane flow meters, are devices used to measure the flow rate of fluids or gases. They operate based on the principle of a rotating vane or impeller. As the fluid flows through the meter, it impinges upon the vanes, causing the impeller to rotate. The speed of this rotation is directly proportional to the velocity of the fluid. A sensor, typically magnetic or optical, detects the rotations and converts them into an electrical signal. This signal is then processed by a display or controller to show the flow rate in the desired units, such as liters per minute or cubic meters per hour.

The construction of a tiivikvoolumõõtja typically involves a casing that houses the impeller and the sensing mechanism. The impeller itself is designed with multiple vanes, often made of durable materials to withstand the flow conditions. The accuracy of these meters can be influenced by factors such as fluid viscosity, temperature, and the presence of particulates in the flow stream. They are commonly used in various industrial applications, including water treatment, chemical processing, and HVAC systems, where monitoring and controlling fluid flow is essential. Different types of tiivikvoolumõõtjaid exist, varying in size, materials, and sensing technologies to suit specific application requirements. Regular calibration is often recommended to ensure continued accuracy and reliable performance.
