What is the difference between a single jet and multi jet meter?
Single jet meters are a low cost option where there is a direct impact to the impeller at the same position from the flow of water. On a multi jet meter there are 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.
It is always recommended to use a robust multi jet meter where possible for much longer life expectancy of the water meter.
What is WRAS approval?
Any water fitting when installed that carries or receives water from the public mains water supply in the UK, must comply with the Water Supply (Water Fittings) Regulations or Scottish Byelaws. These require that a water fitting should not cause waste, misuse, undue consumption or contamination of the water supply and must be of an appropriate quality and standard.
WRAS Approval is the easiest way to demonstrate compliance as it is granted directly by representatives of the water suppliers and is therefore accepted by every water supplier in the UK. WRAS Product Approval: Whole products such as valves, boilers & showers undergo mechanical and water quality testing. This type of approval demonstrates full compliance with requirements of the regulations and byelaws, provided the fitting is installed according to any conditions given with the approval.
WRAS Material Approval: Non-metallic materials & components, such as rubber sheet material & ‘O’ rings, undergo testing only for their effects on water quality. This type of approval demonstrates that the non-metallic material/component does not itself contaminate the water and therefore satisfies this particular requirement of regulations and byelaws.
What is a Woltmann meter?
Sometimes known as a Helix drive meter, these are axial turbine bulk water meters used on larger sizes of 2" and upwards.
