										DigitalFlow GF868 - 火炬气体质量超声波流量计  
										GF868火炬气流量计可以提高石化厂、炼油厂和海上平台的工作效率。它使用专有的算法即时测定火炬气分子量和质量的流量。该仪表用于节约能源,通过识别进入火炬系统的泄漏源减少产品损失。它还有助于加强符合污染控制法规,通过精确控制供给给火炬梢的蒸汽量以减少能源消耗。 
										即使在非定常流,脉冲压力,不同组分和温度,苛刻环境和典型火炬系统的广泛流量范围下,GF868流量计也运行可靠。流速测量从0.1到394英尺/秒(0.03到120米/秒),管道或堆栈直径达120英寸(3米)。无移动部件、孔磨损或堵塞。GF868流量测量与气体性质无关,不需要定期保养

										DigitalFlow XGF868i - Flare 
										Gas Ultrasonic Flow Meter  The XGF868i flare gas flow meter is a 
										low-cost, compact, and 
										explosion/flame-proof transmitter 
										version of the GF868 flare gas flow 
										meter, with CSA, ATEX, and IECEx 
										certifications. Like the GF868 flow 
										meter, the XGF868i improves the 
										efficiency of petrochemical plants, 
										refineries and offshore platforms. It 
										uses a proprietary algorithm to 
										determine instantaneously the molecular 
										weight and mass flow rate of the flare 
										gas. The meter is used to conserve 
										energy and reduce product loss by 
										identifying sources of leaks into flare 
										systems. It also helps improve 
										compliance with pollution control 
										regulations and reduces energy usage by 
										accurately controlling the amount of 
										steam fed to the flare tip.The XGF868i flow meter operates reliably 
										even under unsteady flow, pulsating 
										pressure, varying composition and 
										temperature, harsh environments and the 
										wide flow ranges typical of flare 
										systems. Flow velocity is measurable 
										from 0.1 to 394 ft/s (0.03 to 120 m/s) 
										in pipes or stack sizes up to 120 in (3 
										m) in diameter. There are no moving 
										parts or orifices to wear or clog. The 
										XGF868i's flow measurement is 
										independent of the gas properties, and 
										it does not require regular maintenance.
