1.Project basic information:

  ID*WD: 1620 * 12mm

 medium: hot air

 Design temperature / Pressure: 120℃, / 350 kPa (A)

 Operating density: 3.989 kg/m3

 Scale/ max/ nor/ min flow: 460000 / 300000/ 100000/ 3000 Nm3/h

 Primary element: T26 with 100mm long

 K coefficient: 0.69191, come from automatic calculation

 coefficient of expansion: 0.9995

2.  Mounting and application process:

 (1) Project location: Guangdong Shaosteel plant, 7 # blast furnace, inner diameter 1600mm, there are about 5m straight   pipe section before mounting point, before using thermal mass flow meter measurement, the user reported inaccurate   measurement, error 80000-10000 Nm3/h; Since 2020.11, customer medicated and mounted MMF, start to use.

 (2) Mikoflow multi-variable transmitter is selected, with the primary element is T16, probe rod 100mm long, uni-hole, online   plug/pull, excluding PT 100, temperature menu setting (basically unchanged). For the four-in-one-A type.

 

 (3) When the air volume is 30,000 Nm3/h, the differential pressure value is 74 Pa, close to the theoretical value of the running process!
