 DESCRIPTION
 SYSTEM COMPONENTS
AN HBMAG FLOW METER SYSTEM INCLUDES
• A transmitter and a sensor The transmitter is either compact
mounted integral or remote mounted at a distance of  max
• An internally or externally mounted battery supply or  
VAC or / V AC/DC power supply with battery backup
COMMUNICATION SOLUTIONS
The following communication modules are available
• Encoder interface for AMR and AMI solutions
 OPERATING PRINCIPLE
HbMAG is a microprocessorbased water meter with graphical
display and key for optimum customer operation and information
on site The transmitter drives the magnetic field in the sensor
evaluates the flow signal from the sensor and calculates the
volume passing through It delivers the required information via
the integrated pulse output or communication interfaces as part
of a system solution Its intelligent functionality information and
diagnostics ensure optimum meter performance and information
to optimize water supply and billing
The Mueller HbMAG is configured to achieve up to  years of
battery life in typical revenue applications with the integral
battery and up to  years with the remote battery pack
 DESIGN
HbMAG is a batterysupplied magnetic inductive flow meter
for revenue district and irrigation metering application
 BENEFITS
• Simple placement of the meter  install the meter in a meter
vault or bury it underground The IP  NEMA P design
is unaffected by meter position or inline piping stresses
and there is no requirement for filters or strainers
• Low pressure loss  an unrestricted flow tube ensures
minimal pressure loss even at the highest flow rates
Overall network system pressures can be reduced helping
to prevent leakage from burst pipes and excess stress
placed on pumping stations
• Zero maintenance  designed without moving parts and has
up to a year battery life
• Measurement in both directions  only one meter required
for measuring in both directions
• Intelligent meter  only one meter for leak detection data
logger function and selfdetection of errors
• Compatible with Mueller AMR and AMI solutions
 INSTALLING / MOUNTING
 INTRODUCTION
Mueller HbMAG flow meters are suitable for indoor and
outdoor installations
• Make sure that pressure and temperature specifications
indicated on the device type plate / label are not exceeded
GENERAL INFORMATION
This chapter describes how to install the flow meter in the
compact version as well as in the remote version

The installation consists of two steps
1. Sensor installation
2. Transmitter installation remote version only
 SENSOR INSTALLATION
The installation consists of two steps
1. Locating the sensor
2. Orienting the sensor
3. Mounting the sensor
 LOCATING THE SENSOR
Ensure that the sensor is located in the most optimum place
GENERAL INFORMATION
Ensure that sensor is mounted in correct flow direction as
indicated on label
If process flow direction is opposite of flow direction indicated
on sensor label forward flow rates can be restored via
software parameter FT if factor is adjusted to 
INLET AND OUTLET CONDITION
To achieve most accurate flow measurement it is essential to
have certain straight inlet and outlet pipe lengths as shown
Di sensor diameter
Sensor must be completely full of liquid.
Therefore avoid
• Air in pipe
• Installation at the highest point in pipe system
• Installation in vertical pipes with free outlet
PARTIALLY FILLED PIPES
For partially filled pipes or pipes with downwards flow and
free outlet sensor must be mounted in a Utube

 ORIENTING THE SENSOR
HORIZONTAL PIPES
Sensor must be mounted as shown in upper part of figure
Do not mount sensor as shown in lower part of figure as
electrodes then will be positioned at top where air bubbles
may occur and in bottom where mud sludge sand etc
may deposit
If Empty Pipe Detection is used sensor should be tilted 
as shown in upper right figure to maximize full pipe detection
and provide accurate volume calculations
Note: Physical installation of battery pack may influence
battery capacity Optimal battery capacity is achieved with
battery pack in an upright position Installation examples
marked with dotted cross will affect battery capacity
HORIZONTAL PIPES
Recommended installation is in a
vertical / inclined pipe to minimize
wear and deposits in sensor
INSTALLATION IN LARGE PIPES
The water meter can be installed between two reducers
eg DIN 
With an  reducer the following pressure drop curve applies
The curves are applicable to water

ADVICE FOR GASKET SELECTION
• Only use flat rubber gaskets
• Thickness    mm  ft dependent on
gap / tolerance
• Inner diameter must be larger than bore of flowmeter
• Material should be compatible with process fluid
Hardness should be maximum  Shore A
MAXIMUM ALLOWABLE TORQUES
Standard bolts must be well lubricated and tightened evenly
around gasket
Leakage / damage to flow meter or piping may arise if bolts
are over tightened
TORQUE CALCULATIONS
All values are theoretical and are calculated on the
assumption that
• All bolts are new and material selection is according to EN
 table 
• Gasket material not exceeding  shore A is used between
the flow meter and mating flanges
• All bolts are galvanized and adequately lubricated

 POTENTIAL EQUALIZATION
Liquid potential equalization or grounding is accomplished with builtin grounding electrodes and/or grounding rings The
electrodes ensure electrical connection between liquid and meter providing a stable and accurate measurement
 GROUNDING
The sensor body must be grounded using grounding / bonding straps and/or grounding rings to protect flow signal against stray
electrical noise and/or lightning This ensures that noise is carried through sensor body and that the measuring area within sensor
body is noisefree
METAL PIPES
Connect straps to both flanges with  mm ¹₄ screws
Bonding / grounding straps are part of delivery and

SUGGESTIONS FOR DIRECT BURIAL OF REMOTE SENSOR
Remote sensor is protected to IP / NEMA P and can
be buried
The use of pea gravel at least  inches all around sensor is
recommended to provide some drainage and to prevent dirt
from solidifying on sensor
It also helps to locate the sensor should excavation be
necessary Before covering pea gravel with earth use
electrical cable identification tape above gravel
Run remote sensor cable through a plastic conduit of
minimum  or  mm

 GENERAL SAFETY REQUIREMENTS
WARNING
The pertinent regulations must be observed for
electrical installation.
• Never install the device with the mains voltage switched on!
• Danger of electric shock!
• The electrodes and magnetic current line may only be connected
when the device is not connected to the power supply
• If the housing is under voltage power supply the cover may be
unscrewed by qualified personnel only
WARNING
Mains supply from building installation Class II
A switch or circuit breaker max  A must be installed in close
proximity to the equipment and within easy reach of the operator It
must be marked as the disconnecting device for the equipment
 REMOTE VERSION
