Detailed Product Description: | First, an overview Series gas turbine XFTQ flowmeter is drawing on the flow meter at home and abroad advanced technology optimized design of integrated pneumatics, fluid mechanics, electromagnetism and the theory developed its own set of temperature, pressure, flow sensor and intelligent flow totalizer instrument in one of the new generation of precision, high reliability gas precision measuring instruments, with excellent low and high pressure metering performance, a variety of signal output mode and the low sensitivity of fluid disturbances, widely used in natural gas, coal gas, liquefied petroleum gas measurement of the light hydrocarbon gas and other gases. The product by the state explosion-proof product quality inspection departments GB3836.2000 explosive gas atmospheres using electrical equipment - Part 1: General requirements ", and GB3836.2-2000 explosive gas atmospheres - Electrical Equipment - Part 2: Flameproof" d "GB3836.4-2000" explosive gas atmospheres - electrical equipment - Part 4: Intrinsic safety "i" in "standard inspection proof mark Exd Ⅱ BT4 (flameproof), Exia II CT4 (Intrinsically safe type). Applicable to contain II A, II B, II Class C T1 ~ T4 temperature classification of explosive gas mixtures of 0 (only intrinsically safe) zone 1, 2 dangerous places. Second, product characteristics ? Quality alloy turbine, has a higher steady flow and resistance to the corrosive effect of ? Import high-quality bearings, long life ? Measurement chamber and the ventilation room isolation, to ensure the security of the instrument ? Can detect the measured gas temperature, pressure and flow, the flow of automatic tracking compensation, and display under standard conditions (Pb = 101.325KPa, Tb = 29*K) volume of the gas accumulation; real-time query the values ??of temperature and pressure ? Flow range W (Qmax / Qmin, ≥ 20:1), good repeatability, high accuracy (up to 1.0), pressure loss, low starting flow rate up to 0.6m3 / h ? Intelligent multi-point non-linear correction of the instrument coefficient ? Built-in pressure, temperature sensors, high safety performance, compact structure, beautiful appearance ? Meter with explosion protection, explosion-proof mark Exd Ⅱ BT4 Exia II CT4 with IP65 ? Low-power, a 3.2V10AH lithium batteries can be used continuously for more than 3 years ? Meter factor, cumulative power-down decade of the flow value is not lost Third, the principle When the fluid flow into the flowmeter, the role of the inlet for integrated rectifier, rectifier and acceleration, due to the turbine blades and the fluid flow into a certain angle, the turbines generate rotational torque to overcome the friction torque and fluid moment of resistance, the turbine start rotation. Within a certain range of flow, the turbine rotation angular velocity and volume of fluid flow is proportional to. According to the principle of electromagnetic induction, the use of rotating magnetic sensors from the coaxial signal wheel sensor pulse signal is proportional to the volume of fluid flow, the signal amplification, filtering, shaping temperature, pressure sensor signal into the intelligent flow totalizer count The instrument's micro-processing unit operation processing, and the volume of gas flow and the total is displayed directly on the LCD screen Fourth, the technical parameters: 4.1 Basic parameters: Table 1 Measurement of gas flow in a closed pipe of the implementation of standards - gas turbine flowmeter (GB/T8940-2003) |
