The FLOWMATIC cooling water manifold is equipped with measuring
tubes each with a float inside. The flow volume can therefore be checked
very easily by reading off the position of the float.
The float indicates a flow of up to approx. 12 l/min. When the usable
pressure is sufficient and the channel is open, a considerably greater
maximum flow volume can be achieved. This is however not displayed by
the float.
When the flow is under the minimum of 0.7 l/min the float is not visible.
In the following diagram you can see which scale factors represent which
flow volumes with water as cooling medium.
