10D1475 MINI-MAG MAGNETIC FLOWMETER INSTRUCTION BULLETIN

1.0 INTRODUCTION

1.1 General

The Bailey-Fischer & Porter Series 10D1475 MINI-MAG
liquid flow rate detector. The meter uses the characteristics of a conductive liquid to generate an
induced voltage, directly proportional to flow rate, as the liquid passes internal electrodes. The
resultant voltage is applied to a solid state electronics package that conditions it to an output signal
compatible with conventional receiving equipment.
This instruction bulletin describes two magmeter models. The Models are differentiated by the type of
Converter used with the Primaries as follows:
• 10D1475H - M2 Converter (Integral & Remote Primary versions)
• 10D1475J - 50XM1000 Converter (Remote Primary version only)
The meter's design provides a compact, very low power, obstructionless primary metering element
that bolts between flanges in a process pipeline. Pressure losses in this type of meter are reduced to
levels occurring in equivalent lengths of equal diameter pipeline, thus reducing or conserving pres-
sure source requirements as compared to other metering methods. The compact size of the meter
results in a light-weight unit that requires no
additional support other than that used nor-
mally on pipe runs.
This Flowmeter can be used to meter either
clean or dirty liquids. The meter may be
used with many non-homogeneous liquids
and is as independent of the tendency to
plug or foul as the pipeline in which it is
mounted. By design, only the liner and elec-
trodes are wetted parts and will accommo-
date most acids, bases, water and aqueous
solutions.
Viscosity and density of the metered liquid
have no effect on the measurement accu-
racy of the meter and, therefore, signal com-
p e n s a t i o n i s n o t r e q u i r e d . M e t e r i n g
limitations are confined to a minimum
threshold of electrical conductivity inherent
to the liquid being metered. The degree of
liquid conductivity has no effect upon the
metering accuracy (as long as it is greater
than the minimum level). The liquid tempera-
ture and pressure are limited only to the meter
material specification limit.
With the exception of the primary board, the meter body is a sealed section that bolts between the
customer's pipe line flanges. The body has a TEFZEL
flange faces. The measuring electrodes that contact the process liquid have their ends flush with the
inside of the liner. For accurate results, the meter bore diameter must be centered in the pipeline. For
the larger size meters, spacer sleeves are slipped over the flange mounting bolts. The smaller size
meters use a unique centering device (called a flange adaptor) to center the meter.
The associated electronics package is called the Signal Converter and may be either integrally or
remotely mounted. A typical integral MINI-MAG Magnetic Flowmeter is shown in Figure 1-1. The
integral model 10D1475H Converter housing shown contains an M2 electronics module. Remote
model 10D1475J is furnished with 50XM1000N electronics. Refer to the separate M2 or 50XM1000N
Converter Instruction Bulletins for additional information.
