SPECIAL INSTRUCTIONS FOR REMOVING A METER
THE LINE MUST BE DEPRESSURIZED BEFORE STARTING ANY DISASSEMBLY OPERATION. REMOVING A METER THAT IS
UNDER LINE PRESSURE CAN RESULT IN COMPONENTS BECOMING PROJECTILES, CAPABLE OF CAUSING
PERSONAL INJURY.
SPECIAL FITTINGS AND ACCESSORIES
To accommodate DN15…DN32 meter installations, special fittings and accessories are available Metal meter setters, re-
setters, horns and meter yokes are available for holding the service pipe in proper alignment to the meter and laying length
spacing The metal setters and meter yokes can provide an electrical continuity to protect meters and consumers from
electrical shocks Using a meter setter for the DN40 and DN50 is possible—however, be aware that the setter may affect the
accuracy of the meter Strainer and check valves, (installed on the downstream side of the meter) may also be purchased
as accessories
INSTALLING E-SERIES ULTRASONIC METERS
Outdoor Installations
When installed outdoors in a meter box, the E-Series Ultrasonic meter should have a two- to
three-inch clearance to avoid damage or strain to the service piping or meter, and to
accommodate any "settling" that may occur after installation
The service pipe in the meter box should be properly bedded to ensure that it is not axially
misaligned and that it lays evenly on the bottom of the pipe trench The backfill material covering
the pipe should be placed appropriately to maintain pipe alignment in the event of eventual
ground shifts This will prevent damage to the pipe
The service lines and the water meter must be protected from freezing The earth covering the service line must be adequate
to prevent frost penetration Due to the smaller volume of water, service line pipes will freeze sooner than the main
distribution line
The meter box pit should be excavated below the frost line Even though the meter itself may be positioned above the frost
line, the warmer air rising from the earth below the frost line will reduce the possibility of freezing
Indoor Installations
As a precautionary measure when working with metallic pipes, indoor settings must be checked
for electrical continuity through the service pipe before you remove or service a meter American
Water Works Association (AWWA) policy specifies that service pipes must not be used as an
electrical ground Check your local codes and practices A permanent ground strap or metal setter
must be used if electrical grounding to water services is required in your community
To prevent floor damage, close the valve downstream from the meter before installing or removing a meter
