Environmental classes	M1/E2
Accuracy class	0.5
Operating pressure range for meters equipped with standard mounts	The spoolpiece and transducers may be used at a pressure between 7 and 425 bar(g). For this pressure range the flow characteristics as mentioned in table 2 are applicable. If the minimum pressure is between 3,5 and 7 bar(g), the values for $Q_{\mathrm{max}}$ have to be reduced to 50% of the values indicated in table 2. For T32 transducers only: if the minimum pressure is between 7 and 10 bar(g), the values for $Q_{\mathrm{max}}$ have to be reduced to 80% of the values indicated in table 2. If the minimum pressure is between 3,5 and 7 bar(g), the values for $Q_{\mathrm{max}}$ have to be reduced to 50% of the values indicated in table 2. The measuring range shall be 1:20 minimally.
Operating pressure range for meters equipped with Isolated Mounts on Chordal paths	The spoolpiece and transducers may be used at a pressure between: -0 and 105 bar(g) for meter size 4 to 12 inch; -8 and 105 bar(g) for meter size 14 to 42 inch. For these pressure ranges, the flow characteristics as mentioned in table 2 are applicable. The T200 transducers are always installed based on isolated mounts for meter size 4 to 12 inch with a pressure range of 0 up to and including 259 bar.

Table 2 General characteristics of the family of instruments

The meter has the following flow characteristics:

Meter type	Diameter size			Maximum $V_{\mathrm{max}}$ [m/s]	Minimum $V_{\mathrm{t}}$ [m/s]	Minimum $V_{\mathrm{min}}$ [m/s]
Meter type	Inch	DN	Typical ranges [mm]	Maximum $V_{\mathrm{max}}$ [m/s]	Minimum $V_{\mathrm{t}}$ [m/s]	Minimum $V_{\mathrm{min}}$ [m/s]

	12	300	257~315
	14	350	284~343
	16	400	325~394
	18	450	367~445

	36	900	876~899	23
	42	1050	1029~1048	21

Notes:

If higher values are chosen for $ \mathrm{v}{\mathrm{min}} $ and/or lower values for $ \mathrm{v}{\mathrm{max}} $ it has to be taken into account that $ \mathrm{v}{\mathrm{min}}\leq0,05\mathrm{v}{\mathrm{max}} $ and $ \mathrm{v_{t}}\leq0,2\mathrm{v}_{\mathrm{max}}. $

The flow rates can be calculated as follows:

$$ Q = v \cdot \frac {1}{4} \cdot \pi \cdot D ^ {2} \cdot 3 6 0 0 $$

Where:

Q = flow rate [m $ ^{3} / \mathrm{h} ]$

v = velocity [m/s]

D = diameter [m]

Meter type 3414,3415,3416 and 3417 can be manufactured from 4-42 inch.
Meter type 3418 can be manufactured from 8-42 inch.

Installation conditions:

Inlet piping and flow straightener

The meter is used, with the indicated minimum piping lengths, in one of the following configurations.

Type 3414/3415/3416/3417:

For mild disturbances;

5D piping followed by a CPA 50E straightener followed by 10D piping at the inlet of the meter. For mild and severe disturbances;

5D piping followed by a CPA 55E straightener followed by 10D piping at the inlet of the meter. Type 3418:

For mild and severe disturbances;

5D piping at the inlet of the meter.
