Turbine flowmeter is a new type of intelligent instrument that integrates turbine flow sensor and display integration, which is developed by using advanced ultra-low power single-chip microcomputer technology. It has compact structure, intuitive and clear readings, high reliability, and is not interfered by external power sources. Advantages such as lightning strike and low cost.

Turbine flowmeter is the main type of velocity flowmeter. When the measured fluid flows through the turbine flowmeter sensor, under the action of the fluid, the impeller is rotated by force, and its speed is proportional to the average flow velocity of the pipe. At the same time, the blades are periodic Ground cutting the magnetic lines of force generated by the electromagnet to change the magnetic flux of the coil. According to the principle of electromagnetic induction, a pulsating electric potential signal, that is, an electric pulse signal, will be induced in the coil. The frequency of this electric pulse signal is proportional to the flow rate of the fluid to be measured.
Turbine flowmeters are widely used in the following measurement objects: petroleum, liquid, inorganic liquid, liquefied gas, natural gas, coal gas, and cryogenic fluids. It is widely used in the transfer and gathering stations of foreign liquefied petroleum gas, refined oil and light crude oil, and the first and last stations of large crude oil pipelines for trade settlement. In Europe and the United States, turbine flow meters are second only to orifice plate flow meters for natural gas measurement. In the Netherlands alone, more than 2,600 gas turbine flow meters of various sizes and pressures ranging from 0.8 MPa to 6.5 MPa are used in natural gas pipelines. They Has become an excellent natural gas flow meter. Although the excellent metering characteristics of turbine flowmeters are favored by people, the impression is that they are made of movable parts and have a short service life. They can't help but hesitate when choosing them. After people's unremitting efforts, the situation has changed a lot. Turbine flowmeter is a general-purpose flowmeter, and its products have developed into a multi-variety, full-series, and multi-specification mass production scale.

In addition to the large number of applications in the aforementioned industrial sectors, Farmet's turbine flowmeters are also widely used in some special sectors, such as scientific research experiments, national defense technology, and measurement departments. The use of these fields just avoids its weaknesses (not suitable for long-term continuous use) , Give full play to its characteristics (high precision, good repeatability, can be used in high pressure, high temperature, low temperature and micro flow conditions). In these fields, most of them carry out special structural design according to the special requirements of the tested object, they are special instruments and do not carry out mass production.
