Introduction
General
This manual contains information concerning the application, installation, and operation of the HMS501,
HMS500, HMS1000, HMS2410, MS2500, and HMS5000
full bore flow meters. Keep a copy of this manual with
the flow meter for future reference.
Applications
LCMag electromagnetic flow meters are designed for liquid flow measurement in most industries including water
& waste water, food & beverage, pharmaceutical, chemical, and more. These meters are not suitable for measurement of gases, petroleum products, or other liquid
media with low electrical conductivity. Minimum electrical conductivity of measured liquids is 5µS.
Basic Components
An LCMag electromagnetic flow meter system consists
of two basic components: the flow sensor, and the converter. The flow sensor is the lined tube through which
the liquid flows for measurement. The converter is the
electronic control that provides power to the electromagnetic coils surrounding the flow tube, and that provides
signal processing, flow calculation, and display outputs
for the user.
Unpacking
Always inspect the instrument for damage from shipping
upon receipt. File a damage claim with the carrier if damage is discovered.
Transportation and Handling
Do not lift the instrument from the carton by the converter head. Use lifting eyes where provided for larger
meters, or lift by the sensor body.
When transporting, never use forks of a forklift, chains,
wire slings, or any other object in the flow tube of the
meter. Serious damage to the instrument will result.
Start up and Maintenance
•Before starting up the instrument, always make sure
that there is a suitable connection to ground as described on page 6 of this manual.
•Periodically verify the following: the integrity of the
power supply cables, the proper tightening of the
sealing elements (cable glands, covers, etc.), the mechanical attachment of the instrument to the pipe or
to the wall stand.
The wetted parts of the flow meter (liner and electrodes)
must be selected for compatibility with the liquid being
measured.
The converter must be selected for compatibility with the
environment in which it will operate.
Safety Legend
Before using the instrument, always establish a reliable electrical connection to ground.
Avoid any attempt to repair the instrument. If the instrument is not functioning properly, please call
the nearest authorized representative.
Pay maximum attention during operation.
Caution.
Danger.

Installation
Flow Direction
Before installing the sensor, confirm the direction of the
liquid flow in the piping. The sign of the flow rate is posi-tive, when the flow direction is from - to + as printed on
the nameplate on the sensor body.
If flow direction is reversed after the installation, it is sufficient to reverse the sign of the KA coefficient in the converter (refer to converter installation manual).
Lifting Meters with Eyebolts
Recommended hoisting procedure for sensors with lifting eyebolts.
NOTE: For sensor models HMS1000 and larger, the use
of centering cylinders is recommended.
To facilitate installation, sensors with nominal diameter
greater than 6" are provided with eyebolts that must be
used for lifting as illustrated in the drawing to the right.

Sensor Installation Guidelines
NOYES
Installation
For vertical installations with
descending flow direction contact the manufacturer.
Avoid the installation of the sensor in a long unsupported pipe
line. Always provide adequate
support.
Avoid operation of the instrument with the pipe partially
empty.
Avoid installation of this instrument near bends in the piping
or accessories such as valves.
For vertical installations, use ascending flow conditions, only.
For installations on long runs of
pipe use anti-vibration joints, as
shown
During operation of the instrument, the pipe must be completely full of liquid, or completely empty.
Install the sensor away from
bends in the pipe and accessories such as valves.
Avoid using the closing force of
the nuts to draw the meter and
pipe together over a large distance.
Bring the flange of the piping as
close as possible to the flange
of the sensor before tightening
the nuts on the connection
bolts.
For correct operation of the meter, it is essential that the
sensor and the liquid are at the same electrical potential.
Always connect the sensor and the converter to ground.
Grounding for metallic pipes
Grounding with insulating pipe
Grounding with cathode protection pipe
If the sensor is to be mounted on a pipe made of an
insulating material, it is necessary to perform the following:
•Install two metallic grounding rings between the sensor flanges and the counter flanges of the pipe line
or:
•Use a sensor with the additional grounding electrode.
If the sensor is to be installed in piping with cathode protection, it is necessary to perform the following:
•Insulate bushings to isolate the bolts.
•Install metallic grounding rings to ground the liquid
and use insulating gaskets between the rings.
