Installing the measuring system
• Before installing a new measuring insert, the seal seatings and interior of the housing must be inspected for damage. Used seals are not
be reinstalled.
• Before installation, the O-ring seal and the molded seal on the instrument must be coated with a film of fat (suitable for use in foodstuffs)
before assembly.
• The O-ring seal must be correctly mounted in the seat in the instrument to prevent damage and thus possible leakage. Under no cir-
cumstances must it be mounted in the housing.
• The instrument must be carefully placed inside the housing and pressed firmly into the seal seating. The direction of the arrow on the
cover flange and on the housing must point in the same direction.
• The bolts of the measuring instrument are to be screwed on by hand and then tightened crosswise using a suitable wrench. The torque
for O-ring seals is 40 Nm (M12) or 160 Nm (M16).
• To prevent tampering with the instrument, a bolt should be secured to the housing through a leaded seal.
Notes on safety
• Instruments may only be used for the purpose for which they were intended. An accessory may only be used if it does not affect its cor-
rect function in any way. Aquametro instruments are manufactured according to current standards and directives. Aquametro guaran-
tees the quality of its products as stated in its general terms and conditions. Liability for correct installation and correct operation passes
to the owner or operator once the goods have been accepted. All installation instructions must be carefully observed.
• The facility must be designed to ensure that the flowmeter cannot be damaged. This applies especially to frost damage, torsion in the pi-
ping, excessive thermal expansion of the piping, installation in leaky piping, the entry of foreign bodies or silting up.
• When installing the flowmeter, the clearances of the piping must be taken into account. With a flanged connection, all connecting ele-
ments are to be tightened and with the torque as specified.
• Observe the permissible operating data as stated on the nameplate. Max. test pressure is 1.5 x nominal pressure PN.
• Check the flowmeters periodically for function and to ensure that the connections are properly tightened.
• Release the pressure in the facility before opening it up.
