1 INTRODUCTION
1.1 Scope
This manual provides information and guidance for personnel responsible for the installation,
operation, and maintenance of the MC608A/B Electromagnetic Flow Meter Transmitter
supplied by Flow Technology, Inc.
1.2 Purpose
The contents of this manual are for general information and to describe the operational
characteristics of the MC608A/B transmitter. This manual does not include instructions for
special application or factory repair.
1.3 Description
An Electromagnetic Flow Meter works off the principal of Faraday’s Law. In this
application of the principal the flow meter creates an electromagnetic field perpendicular
to the fluid flowing through the meter housing. An electromotive force (voltage) is
generated in a conductive medium when it passed through a magnetic field. The voltage
created is directly proportional to the density of the magnetic field and the velocity of the
conductive medium. Since the conductive medium is the liquid whose flow is to be
measured, and the length between the electrodes and the electromagnetic field strength
is known, therefore the signal generated is proportional to the velocity of the liquid in the
pipe.
In order for this technology to operate correctly the fluid to be measured does need to be
conductive. The minimum fluid conductivity required is 5 µS/cm for most fluids and 20
µS/cm for DI water.
The electromagnetic flow meters are composed of:
The sensor that must be mounted between two portions of pipe by flanges, threaded
joints, or triclamp fittings.
The converter which drives the sensor and displays or transmits data.
The MC 608A/B converter is provided in a cylindrical aluminum instrument enclosure and
can be interfaced to all Flow Technology magnetic flow meters. It can be mounted directly
on top of the flow meter or remote from the flow meter connected through a pair of
cables, whose maximum length depends on the conductivity of the liquid.
The flow meter Ka and Kb coefficients are established during the factory flow meter
calibration. These factors are normally programmed into the MC 608A/B converter at the
factory prior to shipment, however the key pad of the converter allows the user to enter
or modify these coefficients. This key pad also allows the user to set the full scale flow
rate, define the scaled pulse output, adjust alarm set points, and adjust dosage volume.

The MC608 is available in two main versions:
MC608A – Mains powered 90…264Vac or 12/24 Vac/dc
MC608B – Battery powered or 12/24Vac/dc
2 INSTALLATION
2.1 Inspection
Verify that all parts listed on the packing list are included with your shipment. Note that
there may be more than one package for your shipment. Please check the factory set up
sheet and verify the meter size, full scale flow rate, and analog/pulse output are set up as
required.
2.2 Mechanical Installation of the transmitter to the flow meter
2.2.1 Compact (mounted on flow meter)
The MC 608A/B converter is supplied mounted directly to the flow meter junction box.
In this configuration all interconnection wiring between the flow meter sensor and the
converter have been completed at the factory. Upon flow meter installation, external
wiring for power input and signal outputs will need to be completed. For optimum
installation flexibility the converter display is capable of rotating up to 180˚.

2.2.2 Separate (remote mounted from flow meter)
The MC 608A and MC 608B converters can be mounted up to a maximum of 328 feet
(100 meters) and 98 feet (30 meters) respectively from the flow meter, dependent on
fluid conductivity. When supplied for remote mounting, the flow meter can optionally
be purchased with various cable lengths for interconnection to the converter. This
interconnection cable can be supplied attached to and resin sealed in the flow meter
junction box or the cables can be supplied separately and attached and sealed in the
field. For optimum installation flexibility the converter display is capable of rotating up
to 180˚.

2.2.3 Maximum cable length
When the converter is to be mounted remote from the flow meter, the maximum cable
distance is limited by the conductivity of the fluid to be measured. The maximum
distance is 328 feet (100 meters). Below is a chart to determine maximum cable length
based on the installation operating conditions.
Figure 4 – Cable length vs. conductivity
2.2.4 Grounding
The sensor and converter must be properly grounded to earth potential for the system
to operate correctly. Earth potential is the reference parameter for the flow meter and
without proper grounding issues with zero offset, or flow indication at zero flow will
occur. The sensors and converters all have earth grounding points that can be used to
insure a direct contact with earth ground.
The Flow Technology electromagnetic flow meters are equipment with a third ground
electrode that eliminates the need for grounding rings when installing the flow meter in
insulating piping.
2.3 Electrical Installation
This section provides the professional installer with information for connecting the
MC608A/B to the user's system.

2.3.2 Remote mounted converter, without empty pipe detector
The remote mounted version of the MC 608A/B converter is supplied with an auxiliary
junction box where cables, C012 and C013 from the flow meter junction box will need to
be connected. The converter is normally supplied scaled for a specific flow meter. Please
check the program sheet supplied with the equipment to ensure the converter is
connected to the proper flow meter. Cables C012 and C013 are supplied with metal
ends and identifying letters. Refer to the diagram below for correct terminal location.
