used with a 8020, 8024, 8025 or
8026
If the measuring device does not automatically convert the K
factor, use the following conversion formulae before setting
the parameters of the device:
• K factor in pulse/US gallon = K factor in pulse/litre x 3.785
• K factor in pulse/UK gallon = K factor in pulse/litre x 4.546
Two versions of the S020 in DN15 and DN20 exist, having
different K factors.
Only version 2, identified by the "v2" marking, is available
from March 2012. The "v2" marking can be found:
• on the bottom of the DN15 fitting in plastic:
V2
• on the side of the DN15 or DN20 fitting in metal:
V2
Do not use a fitting S020 in sizes DN6, DN8, DN15, DN15
Version 2 (V2) or DN20 Version 2 (V2) with a paddle-wheel
flowmeter types 8020, 8024, 8025, 8026.
