Azbil Corporation Installation
MagneW
FLEX+/PLUS+
Electromagnetic Flowmeter Detector 2-3
2.3 : Site selection
In order to make full use of the functions of the device, select an optimal installation
site by following the selection criteria below.
CAUTION
Install the unit in a location with an ambient temperature of -30 to +80°C (-22 to +
176°F) and a relative humidity of 5% to 100%. Failing to meet these requirements
could cause damage to the device or cause output errors.
Install the unit away from high-current power lines, motors and transformers to
prevent damage from electromagnetic induction. Failing to meet this requirement
could cause output errors.
Do not install the unit in a location subject to severe vibration or a highly
corrosive atmosphere. Failing to meet this requirement could break the neck of the
detector or cause other damage.
Install the unit as far from direct sunlight as possible to avoid output errors.
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 converter can be used with the device.
