Sprinklers Flow Coefficient Measuring Apparatus

What is the Sprinklers Flow Coefficient Measuring Apparatus？

ZONSKY Sprinklers Flow Coefficient Measuring Apparatus is designed to determine the flow coefficient (K-factor) of sprinkler heads, a key parameter for sprinkler performance in fire suppression. This apparatus measures the flow rate through the sprinkler at various water pressures, calculating the K-factor, which reflects the sprinkler's discharge characteristics. 

This equipment only provides sprinkler test device with nominal flow coefficient less than or equal to 115 as standard; sprinkler with nominal flow coefficient of 161 and 202 is optional test device, such sprinklers are used in special environments and are not commonly used.

Nominal flow coefficient range:
