          Installation Notice

Installed at the lowest point and vertical upward direction              Install exhaust valve at the downstreat of flow meter

Don’t install at the highest point and vertical downward diection          when drop is more than 5m



           
Installed at the lowest point when used in open drain pipe        Need 10D of upstreat and 5D of downstreat



     


Dont’ install it at the entrance of pump, install it at the           Installed at the rising direction
exit of pump
