Product Data Sheet




I recently purchased an WM2-A-C-01, For my application the pipe is vertical with the water flowing downward. The instructions mention that it should be mounted horizontally. Is it ok to mount vertically?
Multi-jet meters use multiple ports surrounding an internal chamber to create multiple jets of water against an impeller. The impeller rotation speed depends on the velocity of the water flow. If your water is flowing downward it will not rotate the impeller as it does in a horizontal pipe or in a up flow condition. Therefore, you cannot install this instrument in a vertical down flow application and receive accurate readings.
