GMWFi / GMWHi
The GMWFi / GMWHi is an axial helix-driven Woltmann water meter for cold water (30 °C) or for hot water (110 °C) conforming to standards ISO 4064 and BS 5728.
It has a detachable mechanism meaning that the meter does not have to be disassembled from the pipe for maintenance. It is connected by PN 10 flanges.
It has a reed switch pulse unit for process control. There is a choice of nine pulse settings that can be programmed at production.
