Multi-jet meter
Heat Meter Accuracy Testing, published by the Department for Business, Energy & Industrial Strategy in November 2016 suggests that Multi-jet meters are:
| …very accurate in small sizes (up to about 50mm pipe diameter) and are commonly used as water meters for residential and small commercial users. Multi-jet meters use multiple ports surrounding an internal chamber to create multiple jets of water against an impeller, whose rotation speed depends on the velocity of water flow. Multi-jets are very accurate at low flow rates, but there are no large size meters since they do not have the straight-through flow path needed for the high flow rates used in large pipe diameters. Multi-jet meters generally have an internal strainer element that can protect the jet ports from getting clogged. |
