Description of the definition of turbine flowmeter

Turbine flow meters, the main type of velocity flowmeters, use a multi-blade rotor (turbine) to sense the average flow rate of the fluid, and derive the flow or total amount of meters. Generally, it consists of two parts, a sensor and a display, and can also be made into a unitary type.

Turbine flowmeters and volumetric flowmeters, Coriolis mass flowmeters are called three types of repeatable and accurate products in flowmeters, while turbine flowmeters have their own characteristics, such as simple structure and fewer processed parts. Light weight, easy maintenance, large circulation capacity (the same diameter can pass through the caliber) and can adapt to high parameters (high temperature, high pressure and low temperature). Up to now, this type of flowmeter products can reach technical parameters: caliber 4-750mm, pressure up to 250MPa, temperature -240-700 °C, other technical flow parameters like this are difficult to achieve.

In addition to the large number of applications in the industrial sector mentioned above, turbine flowmeters are also widely used in some special departments, such as scientific research experiments, national defense technology, and metrology departments. The use of these fields just avoids their weaknesses (not suitable for long-term continuous use) and gives full play to them. Its characteristics (high precision, good repeatability, can be used for high pressure, high temperature, low temperature and micro flow conditions).

The turbine flow sensor is composed of a display instrument. The sensor has the characteristics of high precision, good repeatability, long life and simple operation. It can be widely used in petroleum, chemical, metallurgy, papermaking and other industries to measure the volumetric instantaneous flow rate and volume of liquid.
