Current through Register Vol. 43, No. 12, March 20, 2024
(a) A list of
all makes and models of water flowmeters that have been certified by the water
flowmeter manufacturer to meet the specifications of the chief engineer shall
be maintained by the chief engineer. This list shall be made available by the
chief engineer to the public upon request.
(b) A water flowmeter shall be placed on the
list only if the manufacturer has submitted to the chief engineer all of the
following information for each water flowmeter model:
(1) The water flowmeter manufacturer's name,
address, contact person's name, and telephone number;
(2) the water flowmeter model name or number;
(3) proof that a random sample of
water flowmeters of each model has been tested in accordance with the
requirements of K.A.R. 5-1-4(a);
(4) the last date that the water flowmeter
test equipment was tested and found to be accurate by standards traceable to
the national institute of standards and technology (NIST);
(5) verification that the water flowmeter is
designed and constructed so that accuracy will be maintained over the life of
the water flowmeter;
(6)
verification that the water flowmeter serial number and direction of flow are
clearly indicated on the water flowmeter;
(7) verification that the register is
weatherproof and sealed from all water sources;
(8) verification that the totalizer will read
only in acre-feet, acre-inches, or gallons;
(9) the number of active digits in the
totalizer;
(10) verification that
the memory is nonvolatile;
(11)
verification that the totalizer cannot be reset without breaking the
manufacturer's seal or obtaining the authorization of the manufacturer, an
authorized representative of the manufacturer, or the chief engineer;
(12) verification that the water
flowmeter and register are constructed in such a manner that they can be sealed
by the chief engineer;
(13) a
description of the measuring chamber provided for each water flowmeter model;
(14) specifications of the
flow-straightening vanes installed in the measuring chamber;
(15) the spacing recommendations for each
water flowmeter model in terms of pipe diameters of straight pipe required
upstream and downstream of the water flowmeter sensor; and
(16) the normal operating range of the water
flowmeter.
(c) A brand
or model of a water flowmeter shall be removed from the list of water
flowmeters specified in subsection (a) of this regulation if it has been
demonstrated to the chief engineer that the brand or model of water flowmeter
does not reliably and consistently meet the accuracy standards of K.A.R.
5-1-9(a).
