1. Technical data and basic information
ID*WD: 350*5mm
Medium ：Blast Furnace gas
Design temperature / pressure: 28℃ / 86kPa（A）
WorkingProcess density: 1.0269kg/m3
Scale/max/nor/min Flow: 3000/1000/451/ 400 Nm3/h
Primary element: T26 probe bar, only 100mm insert for 350mm pipe
K-Number: 0.71239, auto compute by software
Coefficient of expansion: 1.0
2. Introduce about application
a. Original DP is mico-DP, produced from Oversea. NO any display about flow and Dp, always both are zero for dp and flow. Never normal works after mount.
b. One 3 in ONE type B mounted on 3rd Sept. 2021 in site. Due to the medium is gas and it is dangerous, and most engineers think it is impossible to measure the very small flow. Many departments, technics & instrument & safety, come site to see the process.
c. Only take about half hour, tanking the old transmitter out, and mount MMF on the 3-valves manifold. After open high/low valves, MMF displays only 2.4Pa and 450Nm3/h. At the time, flow velocity is only 1.65m/s. It is real super- small DP measurement. Let everyone deeply impressed. The process can be seen follow pictures and live video.
