1 Important information for installation: PLEASE NOTE ! • Use only solventless detergents to clean the signal converter housing (polycarbonate). • Temperatures Refer to Section 11 ”Limits” for operating pressure and vacuum load based on flange standards and type of tube liner.
• Strong electromagnetic fields, avoid in vicinity of flowmeter • Straight inlet run minimum of 5 × DN and outlet run minimum of 2 × DN, (DN = meter size), measured from the electrode axis. • Vortex and corkscrew flow: increase length of inlet and outlet runs or install flow conditioners. • Mixing different process liquids: install flowmeter upstream of mixing point or at an adequate distance downstream (minimum of 30 × DN), otherwise display may be unsteady.

5 Installation in the pipeline • Installation material not included, to be provided by customer (stud bolts, nuts, gaskets, etc.) • Pipe flanges and operating pressure: refer to tables on ”limits” in Section 11. • Distance between pipe flanges see fitting dimension ”a”, in Section 10 ”Dimensions and weights”. • Position of flanges Install flowmeter in line with the pipe axis. Pipe flange faces must be parallel to each other, max. permissible deviation: Lmax - Lmin ≤ 0.5 mm ≤ 0.
6 Torques • Tighten stud bolts uniformly in diagonally opposite sequence, see table for number and type. • Column A Torques for Teflon®-PTFE liner. • Column B Torques for liner made of hard rubber. • 10 Nm ~ 1.0 kpm ~ 7.23 ft × lbf Meter Pressure Bolts size rating DN mm PN 10 15 20 25 32 40 50 65 65 80 100 125 150 200 200 250 250 300 300 350 400 450 500 600 700 800 900 1000 40 40 40 40 40 40 40 16 40 25 16 16 16 10 16 10 16 10 16 10 10 10 10 10 10 10 10 10 A B 04 x M 12 007.6 (5.5) 00 (3.
7 • • Grounding All flowmeters must be properly grounded to avoid personnel shock hazard. The ground conductor should not transmit any interference voltages, therefore do not ground any other electrical devices together with this conductor. AQUAFLUX F separate primary head with terminal box • • An FE functional ground must always be connected.
8 Replacement of the separate primary head Switch off power source before commencing work ! 1) Note down terminal assignment before dismantling the ”old” primary head. 2) Install the new primary head as described in the supplied installation instructions. 3) Make electrical connection at the signal converter as described in the installation and operating instructions for the signal converter.
