PRECAUTIONS FOR PROPER USE

Piping for pressure measurement inlet port

• When connecting a coupling to the pressure measurement

inlet port, hold the pressure port attachment with a

spanner and make sure that the tightening torque is

9.8 N m or less. Also, in order to prevent any leakage,

wind a sealing tape on the coupling when connecting.

Piping for atmospheric pressure inlet port

• If there is a possibility of water

entering into the sensor

enclosure through the atmo-

spheric pressure inlet port,

connect a tube to the atmo-

spheric pressure inlet port

through a M5 coupling and

extend the other end of the

tube to a safe place. In this

case, ensure that this end of

the tube does not get clogged.

Fitting of front cover

• Insert the bosses on the front cover into the guide holes at

the bottom of the pressure port attachment, and push in

the direction of the arrow to fit the hook.

When removing the front cover, release the hook first.
