ABOUT THE ESERIES ULTRASONIC METER
The Badger Meter E-Series Ultrasonic meter is an electronic meter using ultrasonic technology and solid-state electronics
contained in a compact, totally encapsulated, weatherproof and UV-resistant housing for residential and commercial
applications. The ultrasonic measurement system has no moving parts, provides long-term accuracy and eliminates
measurement errors due to sand, suspended particles, air pockets and pressure fluctuations.
The Ultrasonic meter is permanently sealed to eliminate the intrusion of moisture, dirt or other contaminants and is suitable
for installation in all environments, including meter pits subject to continuous submergence.
The meter can be installed using horizontal or vertical piping, with water flow in the up direction. The meter will not measure
flow when an“empty pipe”condition is experienced. An empty pipe is defined as a condition when the flow sensors are not
fully submerged.
SAFETY INFORMATION
The installation of the E-Series Ultrasonic meter must comply with all applicable federal, state, and local rules, regulations,
and codes.
Failure to read and follow these instructions can lead to misapplication or misuse of the E-Series Ultrasonic meter, resulting in
personal injury and damage to equipment.

METER STORAGE MODE
All E-Series Ultrasonic meters are delivered in a storage mode so that a meter alarm is not triggered. During storage mode,
the empty pipe shows up on the LCD display as an error message, but it will not trigger a meter alarm. The meter needs to
sense a full pipe for 24 hours for the meter to go from storage mode to normal operation. If installed when the meter is still in
storage mode, the meter will function as expected with the addition of also displaying “err” on the flow rate screen. The meter
will display consumption and, if connected to AMR/AMI, will send a reading to the endpoint. When the meter is in normal
operation, the meter alarm displays immediately upon detecting the empty pipe condition. The alarm clears immediately
after the condition is corrected and the pipe is full. Systems that support the additional alarm conditions will be notified that
an empty pipe condition has occurred.
METER PREINSTALLATION
Take into account the following considerations before you begin an installation:
• Inspect the piping around the meter for suitable conditions. The service line, valves, connections and meter must be
watertight. Repair the piping system if pipes are corroded or damaged.
• Install the meter in the pipeline in a horizontal or vertical position so that the flow arrow on the meter housing points in
the same direction as water flow. Registration should be upright and protected from damage, freezing, and tampering.
• Position the meter so it is accessible for installation, removal and reading.
• Verify that a suitable, electrical grounding wire is properly attached to the upstream and downstream pipe connections of
the meter. The grounding wire provides an alternative path for any electrical current that may exist across the opening in
the line.
• Close the curb (shutoff) valve to relieve water pressure in the line before starting the cutting operation. Provide a high-
quality upstream shutoff valve with a low pressure drop.
• When cutting into a new section of service pipe, flush the pipe to clear chips, pipe dope or other plumbing residue.
• For the DN15… DN32 meters, the line opening for the meter should match the laying length of the meter, allowing slight
additional space for coupling gaskets. The inlet and outlet sides of the meter setting should be axially aligned to
the pipe.
• For the DN40 and DN50 meters, the line opening for the meter should match the laying length of the meter. For optimal
performance and accuracy, it is also recommended that a minimum of five diameters of straight pipe be installed
upstream of the meter.
• The installed meter must not be an obstacle or a hazard to the customer or interfere with public safety.
• DO NOT ATTEMPT TO USE ANY METER AS A LEVER OR CROWBAR TO STRAIGHTEN A MISALIGNED METER POSITION.
THIS COULD DAMAGE THE METER.
• DO NOT ATTEMPT TO INSTALL A METER INTO AN OPENING THAT IS TOO LONG BY FORCING THE PIPING INTO PLACE
WITH THE METER'S COUPLING NUTS. THIS WILL CAUSE SERIOUS DAMAGE TO THE THREADED ENDS OF THE METER
AND HOUSING.
• TO AVOID POTENTIAL PROBLEMS, CORRECT ANY IRREGULARITIES IN PIPE SPACING AND MISALIGNMENT BEFORE
PLACING THE METER INTO ITS POSITION.

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.
Special instructions for removing a meter
Page 7September 2017 ESM-UM-00255-EN-01

Installation Instructions
To prepare for meter installation, follow these steps:
1. Close the meter's inlet-side valve.
2. Open a faucet and wait until water ow stops, to depressurize the system. Do not remove the meter until the
ow stops.
3. Check valves and make necessary repairs to the curb (shuto) valve or inlet side valve if necessary.
4. Before installing or removing a meter, close the outlet-side valve to relieve pressure. Protect the area around the meter
against potential spills or leaks that could occur.
5. To replace an existing meter continue with Step 6. To install a new meter skip to Step 8.
6. Loosen the meter couplings or ange bolts and remove the meter and the old gaskets in the coupling nuts. You may
choose to replace the old gaskets with the provided 9/64 in. thick rubber gaskets.
7. Clean the coupling nuts or ange bolts, removing any pipe dope or dirt from the threads or ange bolts.
8. Check the existing position for proper alignment and spacing. Correct any misalignment or spacing issues.
9. Place the connection gaskets inside the connection coupling nuts.
10. Install the meter in the pipeline in a horizontal or vertical position so that the flow arrow on the meter housing
points in the same direction as water flow. Registration should be upright.
11. For DN15…DN32
a. Start the coupling nuts at the threaded meter ends. Verify that the nuts are properly aligned to avoid cross-threading
or damage to the meter ends. This is especially important for the engineered polymer meter.
b. An eective method for starting a coupling nut is:
i. Position the nut squarely against the meter's spud end.
ii. Turn the nut counterclockwise (in reverse) while holding the nut against the meter spud end. When the first
threads on both the nut and the spud end coincide, you will hear a slight click and feel the nut move into the
starting position.
iii. Tighten the nut by hand until it is "hand-tight".
iv. With an open-end wrench, apply a partial turn. Do not over tighten. For plastic swivel connections, a one-quarter
turn beyond hand-tight is usually sufficient.
11.For DN40 and DN50
a. With meter and gaskets in place, tighten the ange connection bolts. Verify the nuts are properly aligned to avoid
damage to the anged ends.
12. After the meter is installed, open the inlet shuto valve until the meter is full of water and ensure that there are no leaks.
(The more ow you allow through the meter, appropriate for the meter size, the better.)
13. Open the outlet valve until air is out of the meter and service line.
14. Open a valve downstream of the meter and verify that no foreign debris in the water obstructs the operations of
the system.
15. Make sure the meter is installed with the ow arrow on the meter pointing in the direction of ow. Check the read on the
meter to make sure it is registering a positive number. If it is not, make sure the meter is installed in the correct direction.
a. The meter is sent in Storage mode so that customers do not experience alarms during shipment or installation. In
general, a meter may take up to 2 minutes to begin measurement once the meter senses a full pipe.
b. The meter itself does not require a quantity of ow to begin measurement, the meter just requires that the pipe is
cleared of air and lled with water. If the customer is attempting to purge the meter at low ow rates, it would likely be
more dicult and take longer.
16. When the meter starts recording positive ow, note the meter read for your records.

Protect Against Leakage
Before turning on the service water, use care to protect against potential leakage.
1. Shut o the valves on both the inlet and outlet sides of the meter.
2. Open the curb (shuto) valve slowly to pressurize the service line to the meter.
3. Slowly open the meter's inlet-side valve to ll the meter.
4. Check for leaks around the meter and its connections.
5. Slowly open the meter's outlet-side valve to pressurize the consumer side of the system.
6. Open a faucet to allow entrapped air to escape.
7. Once water is owing normally, turn o the faucet.

Unit of Measure
The unit of measure and resolution are factory programmed and options include gallons, cubic feet and cubic meters.
For DN15…DN32 meters, totalized flow displays up to 10 million gallons with a resolution of 0.01 gallons, one million cubic
feet with a resolution of 0.001 cubic feet, or 100 thousand cubic meters with a resolution of 0.0001 cubic meters.
For DN40 and DN50 meters, totalized flow displays up to 100 million gallons with a resolution of 0.1 gallons, 10 million cubic
feet with a resolution of 0.01 cubic feet, or one million cubic meters with a resolution of 0.001.
Rate of Flow
The rate of flow is factory programmed for either gallons per minute or meters cubed per hour, depending on the unit of
measure selected. The LCD displays both the unit of measure and rate of flow. The rate of flow display also serves as the flow
finder indicator. The rate of flow display is shown without leading zeros. When rate of flow is displayed it is updated every
two seconds.
Flow Direction
The direction of water flow is noted on the face of the electronics housing and cast into the meter housing.

AMR/AMI Output
The Ultrasonic meter is an integrated design where the electronics are housed, fully potted and permanently sealed to the
meter housing.
Programmed to the high resolution industry standard ASCII encoder protocol, the Ultrasonic meters have the ability to
transmit meter status indicators to ORION Cellular, Fixed Network (SE) and Migratable (ME) endpoints as part of the extended
encoder/meter reading message. The details can also be read through an IR interface. The output protocol is indicated on the
AMR output wire and is determined at the time of order.
The Ultrasonic meter is available with a wired lead, in-line connector or fully prewired to AMR/AMI devices.
Endpoint Reading Resolution
The reading resolution sent to the reading software is dependent on the endpoint to which the Ultrasonic meter is connected.
Readings reported from the endpoints are the left-most significant digits of the LCD reading.

** 100W will transmit 9 digits through Itron's xed network, but will truncate to the 8 left-most signicant digits for standard mobile and handheld readings.
Status Indicators
Indicators and alarms appear in the display as symbols that illuminate when the condition is active and dim when the alarm
condition is eliminated.
All E-Series Ultrasonic meters are delivered in a storage mode so that a meter alarm is not triggered. During storage mode,
the empty pipe shows up on the LCD display as an error message, but it will not trigger a meter alarm. The meter needs to
sense a full pipe for 24 hours for the meter to go from storage mode to normal operation. If installed when the meter is still in
storage mode, the meter will function as expected with the addition of also displaying “err” on the flow rate screen. The meter

operation, the meter alarm displays immediately upon detecting the empty pipe condition. The alarm clears immediately
after the condition is corrected and the pipe is full. Systems that support the additional alarm conditions will be notified that
an empty pipe condition has occurred.
