A new product
development for a Single Phase Radio Reading Electricity Meter
for consumer use, considered 'the future of electricity metering'.
The design
requirements were to produce two versions of the single phase
electricity meter for Credit and Pre-payment applications.
The prepayment version included a credit accept button.
The meter
design is suitable for very high volumes and required to be
easy to assemble, water resistant and to comply with recognised
industry standards.
The design
uses a combination of moulded components for the housing and
silicone rubber for the button.
To reduce
assembly times and to enhance the protection of the unit, internal
clips were used as opposed to screws. These non-releasable
clips were designed to shear if opening of the case was attempted.
The assembly
uses snap fit features to retain all internal components.
The meter
readings are taken remotely and transmitted to the service
provider periodically.
This revolutionary
approach removes the requirement for a visit for meter reading
and automatically reports disruption to the electricity supply.
Remote programming allows instant tariff changes and pre-payment
of electricity easily made via the phone by the use of credit
or switch transactions.
