GMWI
The GMWI is a tangential helix-driven Woltmann cold water meter conforming to standards DIN 2532 / 2501 and BS 4504.
It has a dry dial register that can be rotated through 360°C and a padlocked cover.
It has a detachable mechanism meaning that the meter does not have to be disassembled from the pipe for maintenance. All sizes have the same mechanism which makes repair easier.
It may be fitted with a reed switch pulse unit. There is a choice of three pulse settings that can be programmed at production (10, 1 and 0.1 m³).
Available in sizes 50mm to 200mm, with nominal flow rates of between 35 m3/h to 450 m3/h.
