About the development of metal tube float meter scale control system of intelligent detection function and effect

Abstract: the scale on the development of metal tube float flowmeter intelligent detection control system the function and effect of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Flow meter is also called the rotor flowmeter, variable area flowmeter is a classic, is a float in the vertical conical tube with the change of flow rate and lifting, change their circulation loop gap formed between the area of flow measurement based on the volume of flow meter. Because of its structure. More flow meter manufacturers choose model price quote you are welcome to inquire, here is about the development of metal tube float meter scale control system of intelligent detection function and effect of the article details. Flow meter is also called the rotor flowmeter, variable area flowmeter is a classic, is a float in the vertical conical tube with the change of flow rate and lifting, change their circulation loop gap formed between the area of flow measurement based on the volume of flow meter. Because of its simple structure, reliable operation, small pressure loss and stable, measurable advantages of low velocity medium, has been widely used in gas, liquid flow measurement and automatic control system. At present, the flow meter was imported and joint products occupy most of the market, the domestic float flowmeter technology generally stay in low level, especially the key indicators and the abroad such as precision, range is still a gap. This study on the traditional flow meter test control system innovation, the development of metal tube float flowmeter is developed intelligent detection and control systems. 1, summary of metal tube float flowmeter flow meter according to the tapered tube made of different materials, can be divided into the glass pipe, plastic pipe and metal pipe. Relative to the glass tube and metal pipe float flowmeter plastic pipe, no risk of taper pipe burst, wider use of temperature and pressure range, but also has a glass tube and plastic pipe flow meter without signal remote transmission function, therefore more extensive application. According to the signal transmission in different ways and metal pipe float flowmeter is divided into on-site instruction and remote transmission. On-site instruction type that is through the pointer indicating flow directly. Far eastone type is divided into air remote transmission and electric remote transmission, gas remote transmission characteristics of the flow meter and electricity far eastone float flowmeter are similar, just far eastone signal is 0. 02 ~ 0. 1 mpa pressure signal. Current signal remote transmission way is mostly about electricity far eastone, zui commonly used electric remote transmission structure of metal tube float flowmeter is based on in situ indicating type, again through the specific mechanical structure to drive differential transformer or Angle sensor, etc. , will float position signal to a differential transformer core angular displacement and angular displacement sensors, then converted into a standard current, voltage signal output. In industrial production, metal pipe flow meter is mainly used for complex, under the condition of bad environment condition of high temperature, high pressure media and various media flow measurement. It except for industrial raw material proportioning measurement, also can carry on the process control, transmission standard signal flow test or directly with the recorder and display systems, and integrated flow measurement. 2, intelligent detection control system hardware structure of the metal flow meter for gas and liquid flow measurement. In a metal tube float gas flowmeter test control system, the data such as temperature, pressure, flow rate are higher accuracy requirement, and require working state stability, high reliability, friendly man-machine interface. , therefore, to research China industrial control is adopted in this system development IPC610 series of hardware system with KingView software platform used KingView intelligent test control system, the real-time data acquisition and control. The system hardware structure is shown in figure 1. Industrial computer IPC - r China 610 the 19 & quot; Rugged 4 u mounted on case, passive backplane or industrial motherboard configuration has 14 slots, impact resistant disk drive bays can support 3 5. 25' 1 and 3. 5. '' Disk drives, front end is equipped with two USB or PS / 2 keyboard I/O interface, the system status LED indicator on the chassis front panel display power supply, hard disk, and the operation of the system voltage, two filter cooling fan can maintain positive air circulation within the whole case. As a result of above characteristic, make the IPC - 610 has strong anti interference, dustproof, shockproof, anti interference flow capacity, widely used in harsh environments of industrial control system. The system host chooses IPC610P4 research China, both the main board, all kinds of input module and RS - 485 communication module. By various all kinds of sensors, Temperature, pressure, flow pulse) , display control function module, measurement control module, analog input interface, and RS - digital quantity input interface Different functions of intelligent unit, composed of 485 communication interface, information interaction with the host, by industrial computer CPU unified coordination, control and processing tasks. Structure of the system will not only satisfy all kinds of analog and digital quantity measurement and control requirements, and USES RS - 485 communication mode, have long transmission distance, large data capacity and strong anti-interference ability, high power devices may be solved well caused by the interference, so as to ensure the accuracy of the whole system. Metal tube flow meter can be used in high pressure and temperature above the boiling point of high pressure gas liquid measurement, but asked to be the current body of work pressure and temperature should be lower than instrument rating.

As a entrepreneur, being trapped in a company under multiple quality problems never appealed to Beijing Sincerity Automatic Equipment Co., Ltd.

Above all, we expect to be a credit to the communities we serve, a valuable resource to our customers, and a place where our dedicated mass flow meter can grow and prosper.

Basically, you cannot have a low flow turbine flow meter without having the right mass flow meter. Since you are going to use it regularly, be sure to invest in one that has a high quality.

The first machine to produce insertion ultrasonic flow meter, the fork density meter manufacturer mass flow meter was invented in v shape coriolis mass flow meter in vortex flow meter manufacturer by tuning fork liquid density meter and was subsequently improved.

Regularly improving mass flow meter in accordance with customer feedback is a great way to show your brand listens and cares.
