The bolts are on the two sides of the pipe horizontally. 1-1/2' and 2' Flange End Water MetersДЇlange end 1-1/2' and 2' meters have 2-bolt elliptical (oval) flanges. In that case, special meter couplings with bushing are available by special order, and the meters are threaded with the NPT tapered pipe thread end of the meter coupling. A couple manufactures make a FEMALE threaded version. These user standard round 1-1/2' or 2' meter couplings and gaskets by size. Most 1-1/2' and 2' Threaded water meters have male threads with standardized AWWA male threads. If replacing, we recommend reducing any 1-1/4' pipe down to 1' with a pipe bushing or reducer coupling, and using 1' meter couplings.

We generally stock 1-1/4' meter gaskets for when these are repaired and replaced, and can special order bushings to downsize to 1' meters as replacements. If you have one, it will likely be replaced by a 1' meter with a threaded bushing. These are mostly legacy meters and discontinued by most manufacturers. These use 1' meter couplings and gaskets.

The 1' water meter has a full 1' meter flow capacity with 10-3/4' lay length. These will use 1' meter couplings and gaskets.

However, the lay length is 9', the same as a standard 3/4' meter, therefore a 1-1/2' long adapter needs to be added for a standard 1' meter setter. It is commonly used to downsize where a 1' meter needs to be replaced with a 3/4' meter without changing meter couplings. 3/4' x 1' MeterДЄ 3/4' x 1' meter (aka 3/4' x 1' x 9' meter) is a 3/4' capacity water meter with 1' AWWA meter threads. These use 3/4' meter couplings and gaskets. It is most often used as a replacement for a 5/8' x 3/4' meter when a 5/8' x 3/4' was originally installed and a higher flow capacity is needed without changing the meter setter or coupling spread. The 3/4' Short meter has a full 3/4' flow capacity, but has the shorter 7.5' lay length of the 5/8' x 3/4'. The threads are 3/4' AWWA meter threads, the same size as for a 5/8' x 3/4' meter. It has a 3/4' measuring chamber capacity. The standard 3/4' water meter has a lay length of 9' from then ends of the threaded spuds. Therefore, either 5/8' x 1/2' or 5/8' x 3/4' may be marked with just 5/8' on the body and register which designated the internal capacity, not the thread size. IMPORTANT NOTE: Most manufacturers use the exact same meter internal and external register components for 5/8' x 1/2' and 5/8' x 3/4' meters, with the exception that 5/8' meter threads are milled down the smaller thread size. We do have an adapter meter coupling available that has a meter nut thread for 3/4', but a 1/2' pipe thread on the nipple end. A standard meter coupling for a 5/8' x 3/4' water meter has male NPT pipe threads on one end and a swivel meter coupling nut with 3/4' AWWA Meter Threads on the other. a 5/8' x 3/4' meter has 3/4'В AWWA Meter Threads and typically hooks up to a 3/4' water service line or larger. 5/8' meters are generally used on older homes where the service tubing size was 1/2' 5/8' x 3/4' Water MeterДЄ 5/8' x 3/4' water meter has a 5/8' water flow capacity just like a 5/8' meter. These use meter couplings and gaskets referred to interchangeably as 5/8' or 1/2'. A standard meter coupling for a 5/8' water meter has male NPT pipe threads on one end and a swivel meter coupling nut with 1/2' AWWA Meter Threads on the other. It has 1/2' AWWA Meter Threads and typically hooks up to a 1/2' or smaller water service line.

Round Flange - 2' and larger - Flange gaskets are the same as standards for flanged pipe.Д¬hart of Meter Size Characteristics: Meter SizeДҐ/8' Water Meter (also referred to as 5/8' x 1/2')ДЄ 5/8' water meter has a 5/8' water flow capacity.

Elliptical Flange (two bolt oval flange) - 1-1/2' and 2'.

Female NPT Threads - 1-1/2' and 2' meters.

Thread sealant should never be used on a water meter threads.

The sealing of a meter coupling nut and meter spud (threaded end of meter) is done by a compressed gasket as opposed to a pipe thread which is sealed by tapered threads and thread sealant. Meter threads are straight threads, unlike pipe thread which is tapered.

AWWA Meter threads are referred to by the size of the meter connection, not the actual measurement.

AWWA Meter Threads (male) - 1/2' - 2' meters.

If you purchased a meter from a supplier outside the USA, it may be metric and ISO standards, and AWWA standard fittings and gaskets may not work properly. Following is information to help you determine the correct size meter or couplings you have or may need. If you are new to the waterworks or metering industry, meter and meter connection sizing can be confusing. Water Meter specifications in the USA are controlled by the American Water Works Association (AWWA).
