14.1 Flowmeter sensor
14.1.1 Protection type according to EN 60529
IP 65, IP 67, NEMA 4X
IP 68 (for external flowmeter sensors only)
14.1.2 Pipeline vibration according to EN 60068-2-6
The following applies to compact devices:
(transmitter mounted directly on the flowmeter sensor)
•
In the 10 ... 58 Hz range with max. 0.15 mm (0.006 inch)
deflection
• In the 58 ... 150 Hz range with max. 2 g acceleration
The following applies to devices with a separate transmitter:
Transmitter
•
In the 10 ... 58 Hz range with max. 0.15 mm (0.006 inch)
deflection
• In the 58 ... 150 Hz range with max. 2 g acceleration
Flowmeter sensor

In the 10 ... 58 Hz range with max. 0.15 mm (0.006 inch)
deflection
• In the 58 ... 150 Hz range with max. 2 g acceleration
14.1.3 Installation length
The flange devices comply with the installation lengths specified in
VDI/VDE 2641, ISO 13359, or according to DVGW (process sheet
W420, design WP, ISO 4064 short).
14.1.4 Signal cable (for external transmitters only)
A 5 m (16.4 ft) cable is supplied.
If you require more than 5 m (16.4 ft), a cable can be purchased using
order number D173D027U01.
Alternatively, the cable with order number AD173D031U01 can be
used for transmitters without explosion protection (model FEP321,
FEH321) from DN15 and for transmitters for use in Zone 2 (model
FEP325, FEH325) from DN15.
Preamplifier
Maximum signal cable length between flowmeter sensor and
transmitter:
a) Without preamplifier:
•
Max. 50 m (164 ft) for conductivity ≥ 5 µS/cm
A preamplifier is required for cables > 50 m (164 ft).
b) With preamplifier
•
Max. 200 m (656 ft) for conductivity ≥ 5 µS/cm
