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.
- Measures
velocity, volumetric
and mass flow
- Delivers

composition
- Measures

- High velocity
