•Avoid using sensors in an environment where the likelihood of splashing or spraying of water, chemicals, and oil to avoid failure and malfunction.
•Consider operating environment according to protection class.
•Do not mount the flow sensor where vibration (98m/s
2
or less) and
impact (490m/s2or less) do not exist to avoid failure and malfunction.
•Operation under low temperature (5 or less) leads to cause damage or operation failure due to frozen moist in the fluid or air.
•Do not short circuit the load.
•Supply power when there is no flow.
•The flow sensor is compulsory turned off for 3s after power supplied.
• Maintenance and inspection should be performed periodically.
• Analogue output may fluctuate by 2 to 3% for 10 minutes after supplying power to the flow sensor.
• Do not poke inside a piping port with a stick.
•A flow rate of the flow sensor, which has a restrictor, may change if the needle turns due to vibration.
• The accuracy may fluctuate by 2 to 3% if a customer removes or replaces piping by themselves.
• When the product is fixed with a screw using the through hole, please tighten it with a 0.3Nm ± 0.05 or less of tightening torque. (Excessive tightening may break the product.)

Mounting and Installation (continued)
Wiring
Connection
Make connection after turning the power off.
•Use a separate route when installing wire. Malfunction stemming from noise may occur if wire is installed in the same route as that of power or high-voltage cable.
Be sure to ground terminal FG when using a switching regulator obtained on the market. If analog output is performed connecting to a switching regulator obtained on the market, switching noise will be superimposed and product specification can no longer be met. This can be prevented by inserting a noise filter, such as a line noise filter and a ferrite element, between the switching regulator and the
sensor
, or by using a seriespower supply instead of a switching
regulator.
Connector
When connecting the connector, insert it straight onto the pin holding the lever and connector body between fingers and lock the connector by pushing the lever claw into the square groove in the body of
sensor
.
•When disconnecting the connector, push down the lever by thumb to disengage the lever claw from the square groove. Then pull the connector straight out.
