A－B（Flow rate difference) ＜Target（Normal）

A－B（Flow rate difference) ＞Target（Abnormal）
High accuracy complies with reliable
monitoring on cooling water leakage at tuyere!

Differential Flow Rate ～Strict Monitoring Standard～
Since cooling water leakage is very important
factor to monitor, very small leakage must strictly
be measured.
•
A company in Japan
Flow rate range: 0-800 L/min
Targeted differential flow rate: A－B＜３ L/min
Differential flow rate: Below than 0.375% of full scale
•
B company in Korea
Flow rate range: 0-500 L/min
Targeted differential flow rate: A－B＜５ L/min
Differential flow rate: below than 1.0% of full scale
*) Accuracy of Electro-magnet Flow meter: ±0.5% of reading

Differential Flow Rate Monitoring ～Field Trial～
A Company – Result of Field Trial
Targeted Differential Flow Rate:
0.375% of F.S.
Result: 0.275%FS: Fully complied
with severe monitoring standard!
