Flow meter manufacturer from China（Kaifeng AFT Instrument Co.,ltd)

Mass flow meters are now favored by users because they directly measure the mass flow of fluid in the pipeline, rather than measuring the volumetric flow and density of the fluid being measured, as calculated in the past, and then calculating it. In addition, its accuracy and stability are higher, the range ratio is larger, but its performance price ratio is too high. For manufacturers, this is a very profitable product, so the development, trial production and marketing of this product has been positive. Principle The principle of the Coriolis mass flowmeter is essentially to utilize the resonance characteristics of an elastomer: for the metal tube components of the fluid flow and the vibration without fluid flow (near the resonance region), the dynamic response characteristics are determined, and the resonance system is determined. The relationship between phase difference (time difference) and mass flow. The difference between the dynamic response characteristic of a metal tube elem...

   On December 24, 2018, two turbine flowmeters were sent to Thailand.They are DN25 and DN6,respectively.Also,the two turbine flow meters are flanged and threaded, respectively.       LWGY series turbine flow meter is a new generation of flow meter optimized by the advanced technology of flow meter at home and abroad.

     A turbine flow meter is a type of turbine that is supported by bearings at the center of the measuring pipe. When the fluid flows through the pipe, it impacts the turbine blades and drives the turbine to cause the turbine to rotate against the fluid resistance torque and the friction torque. Within a certain flow range, for a given fluid medium viscosity, the rotational angular velocity of the turbine is proportional to the fluid flow rate. Thus, the fluid flow rate can be obtained by the rotational angular velocity of the turbine, whereby the flow of fluid through the conduit is ultimately achieved by calculation.     Since the turbine flowmeter is sensitive to the conditions on site, the user should meet its ideal requirements with great satisfaction, so as to maintain the degree of factory instrumentation and obtain the desired measurement data. When the temperature pressure of the fluid medium differs greatly from the reference condition, the volume ch...

Characteristics of liquid ammonia flow measurement: ①The gas-liquid interface at the liquid ammonia stored in the storage tank is generally in a gas-liquid equilibrium state. Liquid ammonia flow measurement should try to avoid two-phase flow. However, liquid ammonia close to the gas-liquid equilibrium state, if the pressure loss is large when flowing through the flow, it is easy to cause partial vaporization, which affects the measurement accuracy. ②The temperature coefficient of liquid density is large. From the ρ=f(t) function table of liquid ammonia, it can be seen that under normal temperature conditions, the density of the liquid ammonia changes by 0.2 ° C or more for every 1 ° C change. Therefore, liquid ammonia metering must be temperature compensated. ③High precision requirements. Liquid ammonia metering should achieve level 1 accuracy. ④The fluid is flammable and explosive. Explosion-proof instruments should be used when selecting the instrument. ⑤The measured medium is cor...
