I work for a UK based company who produces Flow Regulators for foul and storm flows. Our product range can limit flows between 2 and 438l/s. Should you require further information on flow regulators I would be more than happy to assist
Hope this helps
I am a new member to the Eng-Tips forum, and was very interested to read Waseem's comments. I work for a company who design and install Vacuum Flushing systems in the UK. The systems can be utilised in Rectangular/Circular tanks and also in pieline systems.
The system is very energy efficient...
