Sample water and
fresh water pipes
ƕ Use fresh water equivalent of mineral water, which is indispensable for sensor correction.䎃
ƕ
In order to prevent dust contamination from fresh water line, please be sure to carry out cleaning of the line.
Ɣ Tubes to be connected to the sample water inlet, fresh water inlet, and outlet should be copper tubes of 8 mm in
outer diameter.
䚚䎔
Ɣ Normal operating pressure: 0.03 to 0.3 MPa for sample water and 0.03 to 0.6 MPa for fresh water
䚚䯽 When the oil concentration detector is shipped from the factory, its connection ports are for tubes of 8 mm in
diameter (as standard). Use an accessory reducing joint to connect a 10mm-dia. copper tube.
Apply seal tape to the threaded part of the copper tube before coupling the tube to the port.
Restrictions on piping
ƕ䎃 The length from the sample water outlet to the end of piping shall be 2 m or less and the fall shall be within 1.5m.
Be sure to provide hoppers.
ƕ䎃 Piping length between Bilge Separator and Bilge Alarm shall be 3m or less. Bilge Alarm shall be set above the
Outlet height of Bilge Separator. Do not install Bilge Alarm lower than 2m below the top of Bilge Separator.
Operation pressure of Bilge Alarm is 0.03Mpa – 0.3Mpa. In consideration of recommended pressure for Bilge
Separator, adjust the operation pressure.䎃
Caution
Be sure to follow the above instructions to run the oil concentration detector normally.
