●Product Handling
Mounting
•If a commercially available switching power supply is used, be sure to ground the frame ground (FG)
terminal.
•Do not drop, hit or apply excessive shock to the product.
Otherwise damage to the internal components may result, causing malfunction.
•Do not pull the lead wire forcefully, or lift the product by the lead wire.
The product will be damaged, leading to failure and malfunction.
•The product should be flushed out by air blow to remove any dust left in the piping before connecting the
piping to the product.
Otherwise it can cause damage or malfunction.
•Refer to the flow direction of the fluid indicated on the product label during installation and piping.
•Do not mount the product with the display facing downward.
•Do not insert metal wires or other foreign matter into the piping ports.
This can damage the sensor causing failure or malfunction.
•Never mount the product in a place that will be used as a foothold during piping.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
•If there is a risk of foreign matter entering the fluid, install a filter or mist separator on the IN side (entry
side) to avoid failure and malfunction.
Otherwise it can cause damage or malfunction. The product will be unable to measure accurately or control the flow
rate.
Refer to the figure below for the recommended pneumatic circuit.
•If the fluid flow on the IN side (entry side) of the product is unstable, correct measurement and flow rate
control will not be possible.
If a valve is used on the IN side (entry side) of the product, the flow may be disturbed due to the change of the
effective area.
•Do not install a restrictor immediately on the product OUT side (outlet).
Otherwise, the flow control action may be unstable.
