It has many characteristics such as big range of the pressure, broad span of rate, high accuracy, small volume，light weight, convenience of maintaining and use credibility. Meanwhile, it has a strong adaptability to current media and can be used in calculating natural gas, inert gases, air and so on. It is an ideal equipment for sections of city combustion gas, oil-field chemical engineering and scientific research in domestic and abroad. It plays an important role in modern management, the economy check, and energy economization. The standard pattern of flow meter includes measurement and accumulation, which can measure the accumulated flow rate. Moreover, it can equip warm press compensation integrating instrument and various kinds of interfaces according to demands in order to fulfill different needs. 工作原理 as dispute resolution mechanisms, implement fully the petitioners ' cases "third-party" hearings and supervising system of letters and calls, and to resolve the involved law lawsuit into the orbit of rule of law, vexatious, Twining visit visit, disturbing social order and other malicious extortion, resolutely crack down. Five, improving cadres Vitale, provide strong protection for forest development XI General Secretary stressed that the comprehensive revitalization in Northeast China, needs a high quality, solid style, cadres of the dare to play. Cadre cadres is a pledge, should want to do work and able to do good, enthusiasm is paramount. Treat party cadres, it is necessary to Strict management, and warm care, enable the broad masses of cadres work hard work, this is two parallel principles. In strict accordance with the standards of good cadres selection and appointment, the real officers, dare officers, those who want to play, good as excellent cadres at all levels of leadership in the past. At present, some leading cadres work initiative is not high, beyond political, idle, lazy governance governance, not as, slow, messy and a phenomenon still exist to varying degrees, affected and restricted economic and social development. We must mobilize the enthusiasm of cadres as an urgent task, adhere to combination of incentives and constraints, and adhere to the strict management and warm care, practical solution "for the officers not to" problem, motivate cadres and better lead the masses to an undertaking, the cadres and create the new achievement in a dare to play, good at shows as new.

When the conjugate rotors is under the pressure difference (Pressure of go into>pressure of go out) the rotors turn to circle and received the moment alternately. When the rotors circles one circuit, gas four times to the capacity of the metrology room is put out. The number of circle is delivered to the accumulated displayer through the magnetic hermetic rotary device and decelerating device, and then the accumulated output gas is shown. The process and the work principle is shown as Diagram 1.(the diagram is only 1/4 period). The error rectification of figure displaying has been finished before the roots gas meter is put into market, and it meets the standard, so no more adustment is needed. Lubricant device is intalled at the ball bearing of the rotors. The inner structure of the roots gas meter is shown as Diagram 2. 图1 工作原理图 Fig.1 operating principle romoting the construction of rule of law, but also the most basic development environment.

Flowmeters of appropriate models and specifications should be selected on the basis of the measurement of gas flow pressure, flow rate, temperature and direction by processes requirement. (see in the "conversion of flowrate"). The diameter of pipeline, the distance to measurement point and the quantity of the elbows in pipeline as well as whether measure range is proper, all of which will direct influence the sensitivity of flowmeter. 2. Flowmeter need to be settled in proper environment, with temperature -30- -50 ?, humidity 10-90%. Avoid the place of the direct location in open-air and long-term sunlight. Avoid the place of moist or easy flooding. Installation location needs enough maintenance space. 3. Before installation, the encapsulation materials must be removed, and filters or filter covers should be installed at the upstream of the meter to prevent rust dregs, welding slag and other impurities from coming into the measurement room and blocking rotors. 4. While installing, no matter the line between inlet and outlet is vertical or horizontal, the rotor axis and concentric degree of pipeline must be kept. It is suggested to fix ripple compensator in front of flowmeter, if the condition of construction can not satisfy requirement of concentric degree. 5. When the gas pressure fluctuations larger, to ensure measurement accuracy, flow regulator should be installed at the upstream. 6. When flowmeter is installed, the valves in front and back of the meter and bypass line should be set up in case that gas need not be stopped in maintenance. Fig.4, Fig.5 and Fig.6 are A, B and C flowmeter installation pipeline typical system chart (the direction of inlet and outlet is Top in Below out; Below in Top out; Left in Right out), for reference. (Note: Type A is usually used to make the installation of meters) 7. Pipeline with installation flowmeter must be proper, in order not to make flowmeter body to bear abnormal external forces.. 8. Before flowmeter runs, lubricants should be injected (GB486-65 rapid oil H3-5) from the oil mouth to center line mark, and according to operation condition, romoting the construction of rule of law, but also the most basic development environment.

Front and back valves must be closed and after empting the gas the lubricating oil can be added. 9. Before operation, all valves should be turned on or off slowly, to prevent the flowmeter from being damaged in sudden jumping. 10. After some time operation, if filter pressure reduces, filters should be cleaned or replaced; if pressure increases and sensitiveness goes up , clean petrol or kerosene can be used to clean the measure room. 11. If the flowmeter is out of use for long time, lubricating oil should be cleaned out, and measure room should be cleaned with petrol, and the inlet and outlet should be sealed then parked in dry place. 12. Connection size flowmeter installation seen in Table 2 and Fig.7, flange size accords with standard "GB/T9119-2000". 图4 流量计(上进下出)安装管路平面图 安装示意图 Fig.4 Installation of flowmeter (Top in Below out) ?推荐使用的安装方式? as dispute resolution mechanisms, implement fully the petitioners ' cases "third-party" hearings and supervising system of letters and calls, and to resolve the involved law lawsuit into the orbit of rule of law, vexatious, Twining visit visit, disturbing social order and other malicious extortion, resolutely crack down.
