This article describes the current market flow meter type and its advantages, slightly potential, comprehensive introduction of the float flow meter, combined with the development of different countries in the metal tube float flow meter it is necessary to understand the air flow, in many cases, the use of these parameters of the fluid Water, natural gas and other process control equipment, flow measurement is a particularly important method of manufacturing industrial processes. In order to ensure continuous operation of safety, economy, automated production facilities, and automatic adjustment of instrument flow measurement is used to measure the accuracy of production of heat process information and reliable flow in order to control the parameters and equipment throughout the production process One of the main items. In order to meet the needs of the development and development of flowmeters, the development stage of production is promoted and more advanced. The development of science and technology advances in the development of physics, new materials, new technologies, electronic technologies, and computer technologies. The basis of intelligent control theory is the development of flow meters. Flowmeters, laboratory equipment, and more than 100 moments, it is not suitable for industrial applications in various markets. With the development of science and technology, a new type of flow meter has emerged. However, this is "one size fits all" is a flow meter. In order to measure the flow of each different fluid, measuring different flow conditions in different spaces, has the advantage that, at other rates, high-speed flow measurement apertures, existing turbine vortices, for example, potential can be The flow of tiny measurements to provide accurate measurements, measuring the flow rate at low speeds, especially for a variety of flowmeters, such as, in the low Reynolds number box, the rotameter is quite capable of playing an important role. There are no uniform standards for the classification of flowmeters, both domestically and abroad. Seven categories: differential pressure flowmeters are used in industrial process (orifice, venturi) type variable zones (rotor flowmeters), vibration (vortex flowmeters), electromagnetic electromagnetic flowmeters ((), ultrasonics ( Types of Doppler flowmeters, rectangular turbine flowmeters, oval flowmeters for floatation flow rate on the surface of the flowmeter (also based on changes in volumetric flow rate in the rotor rotor flow in response to US dollars) (General Momentum, Originated in 18 In the middle of the century, by changing the typical representative of the vertical of the conical tube), known as the upper and lower flow measurement flow metering cycles, the area of ​​the circle formed between them, eventually in the 19th century, this principle instrument, At the beginning of this century, this was popular in Europe, so camel meters are a bright (ROTOMETER), it is called flowmeter or area flowmeter variable area, in Japan, the United States and the like tools, make account flowmeter variable area Most of the area flow meters used in the flow meter area simply say that, in fact, it has a simple structure, a reliable and reliable pressure loss is small, stable, and can be used in wide measurement Many advantages of the control system and other media are low flow and measured gas flow, liquid you. Divided into three rotameter glass tube float flow meter, metal pipe float flow meter plastic tube, float flow meter, its different manufacturing materials. Rotameter glass tube, plastic pipe rotor flowmeter structure simple float position, air, gas, such as ammonia and clearly visible, easy to read, at a lower cost, in general, with the use of ambient temperature and pressure measurements, transparent and Corrosive media. A multisite that facilitates the visual industrial raw materials, making ratios of measurements. Although there are many advantages, because the only other local display cannot be a sufficiently strong signal for a remote glass tube, the rotameter measures high-temperature and high-pressure fluids, and opaque glass tubes I will not be able to use. Industrial production uses a number of metal tube rotor flowmeters. Divided into, but you can not speak out the position and movement of the metal made by the metal cone of the tube, the use of floating deposits, you need to use the indirect method and the direct visual, float position of the transmission signal The self-adaptive two-meter rotor-type field effect tube enables the local (electricity, gas remote transmission). To measure the signal transmission standard, determine the ratio of corrosive medium to high temperature, high pressure and industrial raw materials, to measure the cumulative flow or directly to the process control, support the use of a recorder, instrumentation display of such metal tube float flow meters.
Pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures. Pigment Powder,Color Pigment,Powder Pigment,Pigment Powder Color Yucheng Jinhe Industrial Co.,Ltd , https://www.hnironoxide.com
Pigments are used for coloring paint, ink, plastic, construction, fabric, cosmetics, food, and other materials. Most pigments used in manufacturing are dry colorants, usually ground into a fine powder. For use in paint, this powder is added to a binder (or vehicle), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion. A colorant can act as either a pigment or a dye depending on the vehicle involved. In some cases, a pigment can be manufactured from a dye by precipitating a soluble dye with a metallic salt.
