3. Precautions for handling
3-1. Working environment, fluid to be measured(1)Ensure that the wetted parts' materials have corrosion resistance against fluid to be measured.
(2)Keep the product away from a strong magnetic field or a source of electric noise.
(3)The product is not explosion-proof specification. Do not use the product in an explosive atmosphere such as flammablegas, etc.
(4)In case pulsation exists in reverse flow, the measurement accuracy is to be affected. Prevent reverse flow using acheck valve, etc.
(5)Avoid installation at a place exposed to direct sunlight and/or rain (Indoor specification).
3-2. Precautions for piping(1)No air shall be in the fluid to be measured. The measurement accuracy is to be affected.
(1)Do not install the product at a place where air accumulation can easily occur (e.g. upstream side of a falling pipe.
(1) Also, before start measurement, remove air sufficiently.
(2)The product can be installed in vertical and horizontal piping. However, the installation position shall be such that its
nameplate is vertical against the ground.
(3)Devices such as a flow-rate adjusting valve, etc., which disturb flow shall be installed in the downstream of the flowsensor.
(4)Avoid installing the product where it is exposed to excessive pressure, such as water hummer, etc.
(5)In case foreign substances, oil, etc., exist in the piping, install the flowsensor after cleaning inside of the pipe.
(6)Make sure to align the flow direction of the fluid with the flow direction indicated by the arrow on the main body.
(7)Around the place of installation, provide enough space for maintenance.
(8)Fluid containing foreign substances cannot be measured. In case they can be in the fluid, provide a strainer of 200 meshesor finer to remove them.
