Water Flow Measure Cup Con-Serv
Different taps give different flows. Taps are given a star rating depending on how efficient they are. Check the star rating for taps in your home using this simple, clever, device.
Also perfect for measuring flow rates for commercial auditing, plumbing troubleshooting and a host of other uses.
Simply place the Con-Serv flow rate measuring cup under the running water and slowly pull the handles apart until the water level stabilises. You can then read the flow rate off the side of the cup.
