ii MagneW
FLEX+/PLUS+
Electromagnetic Flowmeter Detector
WARNING
Before removing the unit, make sure that there is no residual liquid or pressure
inside the piping and the detector to avoid personal injury or damage to the unit.
CAUTION
The detector must be grounded (grounding reference is <100
W
) to avoid output
fluctuation, zero point instability or output drift.
CAUTION
The installation location must satisfy the following conditions to avoid output
errors and fluctuations.
At the installation location:
• The electrical conductivity of the fluid to be measured must match the stated
specification (specs vary according to the converter used) and be more or less
constant.
• The fluid to be measured must be electrochemically homogenized. For example,
if two fluids are mixed at an upstream point, the device should be installed at
a point so that the two fluids can be evenly mixed by the time they reach the
measuring point.
• The distribution of additive matter, if any, must be nearly uniform.
CAUTION
To avoid measurement problems, do not use the MagneW
FLEX+/PLUS+
to measure
the following fluids, even if their electrical conductivity, temperature and pressure
fall within the specifications.
• Fluids that have sufficient electrical conductivity at high temperatures but do not
satisfy the conductance requirements at room temperature (about 20°C (68°F)).
For example, fatty acids or soap.
• Certain fluids that contain surfectants. For example, rinses, shampoos, CWM.
• Conductive adherents. For example, deposition of rosin or conductive material.
• Insulating adherents. For example, oil, kaolinite, kaolin, or calcium stearate.
CAUTION
This model MGG/MGS detector can only be connected to Azbil Corporation's
model MGG10C/14C converter.
No other types of converters can be used with the device.
