Elliptical Flange - an oval shaped meter flange end or companion flange for 1-1/2" and 2" meters that has two bolt holes opposite each other.Dry Contact Switch - A technology where the meter opens and closes a switch allowing a pulse of energy to pass where the switch device itself does not provide the power source.Drop-in Gasket - a gasket for oval/elliptical flange meters that can be dropped into place after the meter is loosely installed with the bolts.A digital pulse will have a very consistent voltage and frequency. Digital Pulse - A pulse output that is in digital format vs an analog pulse.Compound meters are largely being replaced by newer Ultrasonic and Mag meters that are more accurate at all flow rates. Compound meters may have separate high and low use registers or combine reading into one with gearing. At high flow rates, the check valve opens and water is diverted to the turbine measuring element to measure high flow rates. At low flow rates, water is diverted by a closed check valve into a low flow measuring element, usually PD or multi-jet. Compound Meter - A compound meter is really a combination of two measuring technologies with a diverter check valve to switch between them.Do not use a meter for hot water unless specifically designated for that use. Manufacturer standards vary, but cold water can be considered to be 33F to 105F and sometimes up to 140F. Cold Water Meter - Unless otherwise designated as a HOT water meter, all meters should be consider as cold water meters for water at normal ambient temperatures.Similar to a non-return valve or backflow preventer. Check Valve - A valve that allows water to flow in only one direction.An industry organization that sets North American standards in the public water supply industry for meters, valves, pipes, etc. AWWA - American Water Works Association.A technology where a network of antennas, towers or other fixed infrastructure is installed to automatically collect meter reading at set increments via radio transmitted signals. AMI - Automated Metering Infrastructure.Generally a technology for reading water meters in drive-by mode via a short distance ratio signal. Absolute Encoder - An encoder register that outputs the exact position of the number wheels or digital count rather than an incremental pulse.Internal parts and registers are generally interchangeable with the standard 3/4" meter.
#Sensus water meter stuck upgrade#
It is often used to upgrade a formerly 5/8" x 3/4" meter to full 3/4" without having to re-plumb for the longer 3/4" standard lay length, or where space is not available for the longer meter. 3/4" (Short) Meter - This is a full 3/4" bore and measuring capacity meter, but with a 7-1/2" lay length.It is normally used on 3/4" service lines where the full 3/4" flow capacity is required and can't be provided by a 5/8" x 3/4" meter. However, the lay length is 9" inlet to outlet. 3/4" (Standard) Meter - A standard 3/4" meter has a full 3/4" water flow capacity, or bore, and uses the same 3/4" AWWA meter threads as the 5/8" x 3/4" meter.This is currently the most common residential meter size. It uses meter coupling designated as 3/4". The lay length is 7-1/2", the same as the 5/8" x 1/2" meter. is approximately 1.25" (1" NPS - Not 3/4" NPT). 5/8" x 3/4" Meter - This is a 5/8" internal capacity meter but with threads designed for use with 3/4" meter service piping on inlet and outlet.a 5/8" meter uses couplings designated as 1/2" or 5/8" meter couplings This is a common size for older homes and older cities. AWWA meter threads are straight meter threads used with a swivel coupling nut and meter gasket. 5/8" meter and 5/8" x 1/2" meter are used interchangeably. 5/8" x 1/2" Meter - This is the 5/8" standard meter with 1/2" meter threads.Internal components and registers of a 5/8" x 1/2 and 5/8" x 3/4" are normally the same and interchangeable, with the thread size being the only difference. It is referred to as a 5/8" x 3/4" meter. There is a newer meter that has the same 5/8" internal flow capacity and bore, but has 3/4" AWWA meter threads. (5/8" flow capacity with 1/2" inlet and outlet). A 5/8" meter is also now referred to as a 5/8" x 1/2" meter. The original standard of a 5/8" meter was to attach to 1/2" plumbing and had a standard 1/2" AWWA meter thread to use 1/2" meter couplings. the 5/8" designation does NOT refer to thread size. 5/8" Meter - A water meter with an internal measuring chamber flow capacity or "bore" of 5/8".Please contact us if you need assistance with industry terminology, meter sizing, meter typing, or installation questions.
