Table 2—Summary of Major MagneW 3000 PLUS Features
Feature Function
Operating principle based on Faraday’s Law Provides accurate and reliable measurement of process fluid flow rate.
The unit of flow indication can be in percentage, volume flow, mass flow, or
time.
Flange-mounted detector Provides a variety of process connections to match installation
requirements.
4 to 20 milliampere signal or digital-enhanced
output
Provides signal proportional to flow measurement in analog or digital form
depending upon configuration.
SFC and TPS communications Provide means to configure, operate, and troubleshoot MagneW through
SFC and Universal Station or GUS in TPS system.
Optional built-in counter for pulse output
models
• Totalizer: Depending on pulse direction setting, it totals one count at a
time, for forward and reverse flows.
• Totalizer with preset function: A preset value (target total) can be set
between 000000 and 999999. Each forward and reverse flow signal is
counted.
• Forward/reverse flow difference totalizer: The difference in flow volumes
in the forward and reverse directions is calculated and counted.
Optional 1- or 2-contact input • External 0% lock input: Locks the flow rate signal (display, analog
output, and pulse output) at 0%.
• External zero adjustment input: Allows a zero point adjustment from a
remote location.
• External range switching input: Factory setting is
– Range No. 1 or forward direction when opened
– Range No. 2 or reverse direction when closed.
• Built-in counter reset input (optional for pulse output model): Reset
occurs when contact is ON for 0.2 seconds or more. Counting starts
from counter reset value when contact turns OFF.
Optional 1- or 2-contact output • Alarm contact output: An alarm is output when one of the following
abnormal states occurs.
– flow value alarm
– self-diagnosis—coil disconnection, ROM error, RAM error, NVM error,
ADC error, or
– empty pipe detection.
• Range switching output: Factory setting is
– Range No. 1 or forward direction—when open
– Range No. 2 or reverse direction—when closed
• Counter preset status output (for pulse output model): Activates when
the built-in counter reaches the preset value.
• Self-diagnosis alarm output: Activates when the self-diagnosis function
detects an abnormality.
• Empty pipe detection alarm output (with empty-status detection):
Activates when the fluid level in the detector goes below the electrode
level. Alarm is available only when the electrical conductivity of the
liquid is greater than 150µS/cm.
• High/Low limit alarm: Activates when the flow volume exceeds the set
upper and lower limit values.
• Two-stage flow value alarm output (with two contact outputs): An alarm-
actuating contact is output when the simultaneous flow value exceeds
the set two upper limits (H and HH) or the two lower limits (L and LL).
