Maximum Permissible Error

Maximum permissible error: low zone (Q1≤Q< Q2) maximum permissible error is ±5%

When the water temperature is less than or equal to 30C, the maximum permissible error in the high zone (Q2≤Q≤Q4) is ±2%; when the water temperature is> 30C, the maximum permissible error in the highzone (Q2≤Q≤Q4) is ±3%
