Transitional arrangements for existing metering equipment that is not pattern approved
9 Transitional arrangements for existing metering equipment that is not pattern approved
This section applies to metering equipment that was installed in connection with a work before 1 April 2019 and was not pattern approved.
Despite section 3, metering equipment does not need to be pattern approved if—
the metering equipment is metering equipment to which section 8(1) applies, and
the holder of the authority in relation to the metering equipment gives written certification to the Minister from the manufacturer that the maximum permissible error of the metering equipment was not more than plus or minus 2.5% after manufacture.
Despite sections 3 and 7, metering equipment does not need to be pattern approved or validated if—
for open channel metering equipment—within 12 months before the application day for the equipment, the metering equipment is—
checked for accuracy by a duly qualified person, and
checked again by a duly qualified person at intervals of not more than 12 months, and
for other metering equipment—within 5 years before the application day for the equipment, the metering equipment is—
checked for accuracy by a duly qualified person, and
checked again by a duly qualified person at intervals of not more than 5 years, and
after any subsequent maintenance work on the metering equipment is carried out that affects its metrological performance, the metering equipment is checked for accuracy by a duly qualified person, and
the checks referred to in this subsection determine that the maximum permissible error of the metering equipment is not more than plus or minus 5% in the field.
For the application of section 7 to metering equipment referred to in subsection (3)—
for open channel metering equipment—the first interval of 12 months for validation after the application day ends 12 months after the existing validation, and
for other metering equipment—the first interval of 5 years for validation after the application day ends 5 years after the existing validation.
A record must be kept of the way in which metering equipment is checked under subsection (3).
A report setting out the steps taken in relation to the metering equipment must be given to the Minister by a person who intends to rely on this section.
The report must be—
given to the Minister before the application day for the mandatory metering condition that applies to the metering equipment and as soon as practicable after each subsequent occasion on which a check is carried out under this section, and
given in the approved form and approved manner, and
accompanied by any documents given by the duly qualified person to the person reporting that relate to the checks carried out by the duly qualified person.
In this section—
existing validation has the same meaning as in section 8(1)(a).
metrological performance has the same meaning as in AS 4747.
