Water Meters are used to measure the volume of water used within residential and commercial buildings and there are a number of types of water meters that can be used.
Both single jet and multi jet waters meters are suitable for sub/secondary billing for domestic applications, batch control and water monitoring in industrial or commercial applications.
Single jet water meters are a low cost option where there is a direct impact to the impeller from the flow of water.
Multi jet water meter have several points at which the water rotates the impeller. This gives a much longer life and retains accuracy as the load is evenly placed across the impeller.
Multi-jet water meters are very accurate at low flow rates, but are not used in larger sizes, since they don't 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.
It is always recommended to use a multi jet meter rather than a single jet meter if possible.
