2 Description
Repeatability
≤ 0.2 % of rate
Attenuation time
τ ) ≥ 5 s
As jump function 0-99 % (corresponding to 5
Excitation frequency : 6 1/4 Hz
Entry and exit lengths
We recommend a straight entry length of 3 x DN upstream of the equipment and an exit length of 2 x DN
downstream of the equipment
Ambient conditions
Ambient temperature
-10 °C to 50 °C
Type of protection
IP 65 (acc. to EN60529)
Resistance to vibration
2
Max. acceleration: 15 m/s (10−150 Hz)
Electromagnetic compatibility
The equipment corresponds to the NAMUR recommendations NE21. Electromagnetic compatibility of
tooling used in process and laboratory control equipment 5/93 and EMC Directive 89/336/EEC
(EN50081-1, EN 50082-2).
Attention!
!
The EMC protection is limited when the housing cover is open.
Process conditions
Process temperature
Permissible measuring agent temperature: -10 °C to +110 °C
Conductivity
At least 50 µS/cm
Air pockets
Ensure that the measuring equipment is always filled completely. Partial filling creates an additional
source of measuring error just like gas bubbles entrained in the medium.
Process pressure limit
Max. permissible pressure: 10 bar, depending on fluid temperature (refer to p-T rating page GB 7)
Max. perm. measuring agent temperature and pressure
(refer to p-T rating page GB 7)
Loss of pressure
The Miniflow does not have any parts which protrude into the measurement pipe. The level of pressure
loss is negligible.
