ENGLISH
Pipe diameter DN15 to DN400; determine the appropriate diameter using the flow-velocity-
DN diagrams (see Annex)
Max. fluid temperature depends on the fitting material; refer to the instruction manual of the fitting used
Fluid pressure depends on the fitting material; see temperature-pressure diagram (§ 2.1)
Fluid viscosity 300 cSt max.
Rate of solid particles max. 1%
Measuring range
- Pulse version 0,3 m/s to 10 m/s
- Sinus version 0,5 m/s to 10 m/s
Linearity
≤ ±0.5 % of the full scale
1)
Repeatability ≤ 0.4% of the measured value
1)
Accuracy ≤ ±0.5 % of the full scale
1)
, with calibration on site (for example by using
the Teach-in feature of a transmitter 8025 in a remote version)
≤± (0.5 % of the full scale
1)
+ 2.5% of the measured value), with standard K factor
1)
These values have been determined in the following reference conditions: fluid = water, water
and ambient temperatures = 20 °C, min. upwards and downwards distances respected,
appropriate pipe dimensions. Full scale = 10 m/s
Power supply none
Output data up to 300 Hz, approx. 2,8 mV peak-to-peak/Hz under a 50 kΩ-load
(frequency = K factor x flow rate; the K factor value must be taken from the instruc-
tion manual
of the fitting)
Cable length max. 10 m, shielded
Cable cross section, max. 1.5 mm
