ALPHEUS type ASLimiters have the task of restricting the pass forward flow to a predetermined value independent of the water level, allowing a constant flow. With the ALPHEUS-Flow Limiter, Type STANDARD, you are assured of a constant pass forward flow irrespective of head.

Short function description

In dry weather the outlet control plate is completely opened. During storm conditions the internal float rises and activates the control mechanism. The water rises from below into the housing (diving bell), so that the float moves vertically upwards. The float is linked to the inlet control plate, so that the desired flow rate is maintained.

The float rises and falls with the water level thereby opening and closing the orifice plate to maintain the desired flow rate. The housing fulfils the function of a diving bell. As the water level fills the air is compressed in the housing and restricts the rising level of the water. This ensures that the float doesn’t have to travel the same distance as the actual head and minimizes the dimensions of the unit. The orifice plate can be completely opened with the hand release in the event of a blockage.

Dimensions

The float rises and falls with the water level thereby opening and closing the orifice plate to maintain the desired flow rate. The ALPHEUS-Flow-Limiter Type STANDARD can be manufactured in the following sizes DN 100 up to DN 1000 for desired flow rates of 2 l/s up to 2400 l/s. Larger units and special requirements can be produced on request.
