Technical Field

The invention belongs to the technical field of flowmeters, and particularly relates to an IC (integrated circuit) card industrial flowmeter controller and a control method thereof.

Background

The flowmeter is known by its english name flowmeter, which is defined by the national committee for the examination and determination of scientific and technical terms as: meters that indicate the measured flow rate and/or the total amount of fluid in a selected time interval. Simply a meter for measuring the flow of fluid in a pipe or open channel.

The flow meters are classified into differential pressure type flow meters, rotor flow meters, throttle type flow meters, slit flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, and the like. Classifying according to media: liquid flow meters and gas flow meters. Metering is on the eye of industrial production. The flow measurement is one of the components of the measurement science and technology, and has close relation with national economy, national defense construction and scientific research. The work is well done, the flowmeter has important effects on ensuring the product quality, improving the production efficiency and promoting the development of scientific technology, and particularly has more obvious status and effect in national economy in the current times that the energy crisis and the industrial production automation degree are higher and higher.

The unit m3/h is commonly used in engineering and can be divided into instantaneous Flow (Flow Rate), namely the amount passing through the effective section of a closed pipeline or an open channel in unit time, and Total Flow (Total Flow), wherein the flowing substances can be gas, liquid and solid; the cumulative flow rate is the cumulative amount of fluid flowing through the effective cross section of the closed conduit or channel over a certain time interval (one day, one week, one month, one year). The accumulated flow rate can also be obtained by integrating the instantaneous flow rate with time, so that the instantaneous flow rate meter and the accumulated flow rate meter can be mutually converted. In industrial sites, meters that measure fluid flow are collectively referred to as flow meters or flow meters. Is one of the most important instruments in industrial measurement. With the development of industry, the requirements on the accuracy and range of flow measurement are higher and higher, and in order to adapt to multiple purposes, various types of flow meters are developed in succession and widely applied to industries such as petroleum and natural gas, petrochemical industry, water treatment, food and beverage, pharmacy, energy, metallurgy, paper pulp and building materials, and the like.

The flow measurement is widely applied to various fields of industrial and agricultural production, national defense construction, scientific research and foreign trade and people's life. In the production of the petroleum industry, from the exploitation, transportation, smelting and processing of petroleum to trade sale, the flow measurement runs through the whole process, and the flow measurement cannot be carried out in any link, otherwise, the normal production and trade interaction of the petroleum industry cannot be ensured. In the chemical industry, inaccurate flow measurement can cause chemical component distribution ratio imbalance, product quality can not be guaranteed, and production safety accidents can also happen seriously. In the power industry, the measurement and regulation of medium flow of liquid, gas, steam and the like are important. Whether the flow measurement is accurate or not has great economic significance for ensuring that the power plant operates under the optimal parameters, and the flow measurement becomes an important link for ensuring the safe operation of the power plant along with the development of high-temperature high-pressure large-capacity units. Such as the interruption or reduction of the instantaneous feed water flow of a large-capacity boiler, can cause serious dry pot or pipe explosion accidents. This requires that the flow measuring device not only perform accurate measurement, but also send out an alarm signal in time. In the production of steel industry, the flow measurement of circulating water and oxygen (or air) in the steel making process is one of the important parameters for ensuring the product quality. In the industries of light industry, food, textile and the like, flow measurement cannot be avoided.

The transducers used in relatively many applications are of the clip-on type and of the plug-in type. The monophonic ultrasonic flowmeter has a simple structure and is convenient to use, but the flowmeter has poor adaptability to the change of the flow state distribution, the rapid development of the microelectronic technology and the computer technology greatly promotes the updating and upgrading of the meter, and the novel flowmeter emerges like a bamboo shoot in spring after rain. To date, hundreds of flow meters have been said to be on the market, and many troublesome problems in field use are expected to be solved. The recent flow measurement technique developed in China at a later stage is provided at the upstream end of the measurement flow path 6 with respect to the orifices 11 and 12 for reducing the inflow of the fluid to be measured into the orifices 11 and 12, a measurement control section 19 for measuring the propagation time of the ultrasonic wave between the ultrasonic transducers 8 and 9, and a calculation section 20 for calculating the flow rate based on the signal of the measurement control section 19.

The flowmeter avoids ferromagnetic objects and devices with strong electromagnetic fields (such as large motors, large transformers and the like) as much as possible so as to prevent the working magnetic field and flow signals of the sensor from being influenced by the magnetic fields. A flow signal line and an excitation line between the transducers of the sensor and the spoon. However, from the analysis of the damaged parts in a lightning fault, the induced high voltage and surge current that cause the fault are mostly enough to be drawn from the control room power lines, with fewer of the other two paths. Because the opportunity that the electromagnetic flowmeter measures the solid phase or dirty body that contains suspension is far more than other flow meters, the probability of failure that the inner wall adhesion layer produces also is higher relatively.

Compared with the prior art the problem that exists:

the existing controller has the defects of complex structure, incomplete function, and inaccurate and reliable performance.
