Warning/cautions at the time of design & selection
1. Fluid medium
Danger
■
A flammable fluid must not be used.
Warnings
■
The product can not be used as a business meter.
Since it is not conformed to the Measurement Law, please do not use the product for the commercial purpose. Please use the product
as an industrial sensor.
■
Please do not use the product with other than applicable fluid medium, or the accuracy can not be guaranteed.
■
When flowing compressed air, please use a clean air conforming to JIS B8392-1:2003 Grade 1.1.1 ~ 1.6.2. Please install a filter, an air
dryer and an oil mist filter (micro alescer) onto the primary side (upstream) of the sensor since the compressed air from the compressor
contains drain (water, oil oxide and foreign material, etc.) Mesh (wire net) in a sensor is used to rectify the flow in the pipe. Please
always install a filter since this mesh is not a filter to remove foreign materials, etc.

2. Working Environment
Danger
■
Flammable environment
Please do not use the product in flammable gas environment. Since the product is not explosion-proof, explosion or fire may be
caused.
Warnings
■
Corrosive environment
Please do not use the product in an environment containing corrosive gas such as sulfurous acid gas, or etc.
■
Ambient / fluid temperature
Please use the product within the ambient / fluid temperature ranges 0 to 50 °C. Even in the specified temperature range, please do not
use the product where ambient / fluid temperatures change suddenly, and form dew condensations.
■
Working pressure range / Working flow range
lease use the product in accordance with specifications. If used out of the maximum working pressure and working flow range, the
product may result in failures.
■
Drip proof environment
The protective structure of this product is equivalent to IP40. Please do not install the product where moisture, salt, dust or swarf is
contained, or where pressurized, or depressurized, neither. The product can not be used where the temperature changes suddenly or
has high humidity since a failure by dew condensation may be produced in the body.
■
When a valve is used in the primary side of the sensor, an oil-free valve must be used. The sensor may malfunction or be destroyed
by splash of grease oil, and etc. Please install filter to prevent flowing abrasion powder, which may be generated from a valve, into a
sensor.
■
Please use dry clean gas, which do not contain dust , oil mist and corrosion ingredients such as chlorine, sulfur, acid or etc.
■
Depending on the property of fluid, bad influence on performance may be caused when such fluid remained in the sensor for a long
time. Please do not seal up a fluid in the plumbing for a long time.
