O-shaped siphon
A siphon reduces the temperature to almost the ambient temperature. The defined water
column only causes minimal (negligible) measured errors and minimal (negligible)
thermal effects on the device.
Observe the maximum permitted ambient temperature of the transmitter!
• Ideally, mount the measuring device with the O-shaped siphon below the tapping point
The device may also be mounted above the tapping point
• Fill the siphon with liquid before commissioning
