To aid installation in strongly fluctuating water levels, e.g. in rivers or lakes, there is a
floating body COA 110-50 available (Fig. 3.10).
Flow operation
The COA 250-A flow assembly (Fig. 3.11) with automatic self-venting is suitable for use
in pipelines or hose connections. The inlet is at the bottom of the assembly, the outlet at
the top (connection thread G ¾). It can be installed in a pipe by using two 90° pipe
brackets to allow inflow to the assembly (Fig. 3.12, Pos. 6).
