Important:

Make sure that the specied maximum permitted operating pressure of the ow meter

cannot be exceeded, whatever the operating mode of the system. Note the ow meter

range that is dependent on the viscosity of the uid to be measured.

Important:

Make sure that the ow meter is always completely lled both in inow and outow

and that the outow has a little back pressure. This prevents the meter being damaged by

a sudden and steep increase of ow and at the same time improves measurement accuracy.

Important:

Please ush out the pipe lines and the tank thoroughly, to prevent contamination

within the ow meter.

Important:

When mounting the ow meter, you must take great care that the seals are not damaged and

correctly placed in the hydraulic connections of the ow meter. Wrongly installed or dama-

ged seals lead to leakage and to a leaky system, which may have dire consequences.

Please make sure that ow meters with EPDM seals do not come into contact with oil and

greases on a mineral oil basis. These uids can decompose the seals.

The yellow plastic plugs in the hydraulic connections of the ow meter protect the meter

against dirt and contamination during storage and shipping. Before mounting the ow meter

you have to remove these plugs so that in- and outow is free and open.

• Plug assignment of preamplier

Important:

Only use well-shielded cables for the connection cable, with a wire cross section of

≥ 4 or 5 x 0.25 mm

. Please make sure that the housing of the round plug is metallic, that it

has a connection for the shielding and that the potential of the earth conductor PE is

connected with the cable shielding and the housing of the preamplier.

Important:

Please make sure that no extra inductive elements are connected in the power supply of the

ow meter, such as contactors, relays, valves etc.

These components are potential sources of interference (especially if the inductive elements

are not provided with an adequate protective circuit), generate high interference pulses,

when switched and can interfere with the functioning of the ow meter, although this

complies with the electromagnetic compatibility directives.

Working life is dependent on operating conditions and thus the specic properties of the

devices, limited through wear, corrosion, deposits or age. The operator is responsible for

regular control, maintenance and recalibration. Any indication of a malfunction or damage

prohibits any further use. On request, we can supply you with a borrowed device for the

duration of repair or overhauling. We advice to a yearly control and recalibration.
