SEPARATE TYPE ELECTROMAGNETIC
FLOWMETER
DATA SHEET
FMB1, 2/ FMC
The electromagnetic flowmeter is an instrument to measure
the volumetric flow rate of liquid simply by applying a mag-
netic field from the outside utilizing the fact that an electric
conductor which crosses a magnetic field at a certain velocity
causes voltage to be induced in proportion to the velocity,
which is known as Faraday’s law.
This flowmeter is designed with the latest electronics tech-
nology and magnetic/electric field analyzing technology, real-
izing a compact and light-weight structure and measurement
with high accuracy.
FEATURES
1. High accuracy
The adoption of the optimum magnetic field design using
the 3-dimentional finite element method has minimized
the effects of flow velocity profile and materials of adja-
cent piping. At flow velocity of more than 1m/sFS,the
measurement accuracy is as high as ± 0.5% of
indicatedvalue when the flow is above 20%FS.
2. Wide range
Measurement range: 0 to 0.3 ... 15m/sec in flow velocity
3. High-reliability structure
The sensor terminal box is a sealed 2 - chamber structure,
practically free from dew condensation and sudden sub-
mergence. The adoption of stainless housing assures ex-
cellent anti-environment efficiency.
4. Easy-to-see display
LCD with back-light allows easy check of display even in a
dark place. Instantaneous flow and integral volumetric
flow are displayed at the same time.
5. Free power supply
The flowmeter operates on power supply 100 to 240V AC,
50/60 Hz, eliminating the need for selection of power volt-
age.
6. Application of international standards
The overall length of flange type flowmeter conforms with
ISO draft standards. (Meter size : 6A-200A)
