!
Note!
In the remote version, the necessary minimum conductivity also depends on the length of the connecting cable

Medium pressure range
(nominal pressure)
• EN 1092-1 (DIN 2501) = PN 16
• ANSI B 16.5 = Class 150
• JIS B2220 = 10 K
Pressure tightness
Measuring tube: 0 mbar abs (0 psi abs) with a fluid temperature of
≤
60 °C
Limiting flow
The diameter of the pipe and the flow rate determine the nominal diameter of the sensor.
The optimum flow velocity is between 2 and 3 m/s. The velocity of flow (v), moreover, has to be matched to
the physical properties of the fluid: v >2 m/s (in the case of fluids that cause buildup, such as wastewater sludge
etc.).
Flow characteristic values
Pressure loss
• No pressure loss if the sensor is installed in a pipe with the same nominal diameter.
• Pressure losses for configurations incorporating adapters according to DIN EN 545
