Turbiinivooluhulgamõõtjad

Turbiinivooluh, also known as turbine flowmeters, are devices used to measure the volumetric flow rate of liquids and gases. They operate based on the principle of a turbine wheel that spins when fluid passes through it. The speed of the turbine's rotation is directly proportional to the flow rate of the fluid.

The turbine wheel is typically constructed from materials like stainless steel or plastic, depending on the application and the type of fluid being measured. It is mounted on a low-friction bearing within a housing that directs the fluid through the turbine. As the fluid flows, it impinges on the turbine blades, causing it to rotate.

A sensing mechanism, usually an electromagnetic pickup or a photoelectric sensor, is positioned near the turbine. This sensor detects the passing of the turbine blades and generates electrical pulses. The frequency of these pulses is proportional to the rotational speed of the turbine and, consequently, to the flow rate.

The electrical pulses are then processed by electronic circuitry, which converts them into a readable flow rate display, such as liters per minute or cubic meters per hour. Turbiinivooluh are known for their accuracy, wide dynamic range, and relatively low cost. They are commonly used in various industries, including oil and gas, water treatment, and chemical processing, for applications such as custody transfer, process control, and monitoring. However, they can be sensitive to viscosity changes and may require calibration for optimal performance.
