acre-feet, acre-inches or gallons. Acre-inches are preferred.
The registry shall be protected from the elements. Totalizers
shall have sufficient capacity to record for a period of one year
the quantity of water diverted from each water source, or combination
of sources for installations supplied by multiple water sources.
Totalizers shall be direct reading and the multiplier shall be
clearly indicated. The meter also shall have a rate-of-flow indicator
showing: (a) Instantaneous flow in gallons per minute, or (b)
A sweep hand indicator from which rate of flow can be determined
by timing. The registry shall be provided with a method for sealing
with a wire or a lead seal to prevent unauthorized tampering or
removal.
.
The meter shall have
a rated accuracy of plus or minus two (2) percent of actual flow
within the range of flow for which the meter is designed. The
meter shall be capable of accurately registering the expected
operating range of discharge.
.
The meter shall have
a pressure rating to fit the application and shall be used only
within its designed pressure range.
.
The meter size, serial
number and the direction of flow shall be clearly stamped on the
body of the meter. The inside pipe diameter for which the meter
has been calibrated shall be clearly shown on the meter to the
nearest 0.001 (one one-thousandth) of an inch.
.
All flow meters required
by Rule 4 of these rules and regulations shall be installed to
the following specifications:
.
The meter shall be installed
in accordance with the manufacturer’s specifications and
in such manner that there will be a full pipe flow of water at
all times while water is being measured. Full pipe flow may be
obtained by using butterfly valves or by raising the pipe beyond
the meter to a point above the level of the meter.
.
To increase accuracy,
the meter shall be placed in the pipe not less than five pipe
diameters downstream from any valve, elbow, or any other obstructions
which might create turbulent flow, or as recommended by the manufacturer.
There also shall be at least one pipe diameter of unobstructed
flow on the downstream side of the meter. Straightening vanes
shall be installed in the pipe if above conditions cannot be met.
.
The meter propeller
shaft shall be positioned parallel to the pipe and aligned with
the centerline of the pipe.
.
All flow meters required
by rule 4 of these rules and regulations must be maintained in
accordance with the following specifications:
.
Each flow meter must
be kept in working order and clear of debris, vegetative growth,
or other material that would impede operation.
.
Any malfunctioning flow
meter must be reported to the District office at Gering, Nebraska,
within twenty-four (24) hours after discovery. Malfunctioning
flow meters discovered on any day other than working days (weekends
and holidays) shall be reported before the office closes on the
first working day following the discovery. During the malfunctioning
period, the producer shall use a substitute meter from the District,
if available, to determine water consumption. If no such meter
is available, any reasonable method approved by the District shall
be used to determine water consumption.
When
any flow meter is removed for servicing or replacement, the owner/operator
must keep records of the flow meter reading.
A meter may be removed for off-season storage, but should be stored
in such a matter that will prevent freezing or damage by rodents.
