1Product description
Bypass 72 is a complete level measuring system in a bypass tube,
complete with VEGAFLEX sensor.
Bypass 72 with VEGAFLEX sensor is immediately ready for operation
and requires no adjustment.
Depending on the process pressure or process temperature,
VEGAFLEX 61 and VEGAFLEX 66 sensors can be used in
combination with the bypass tube.

2Mounting
Take note of the attached mounting instructions and the operating
instructions manual of the corresponding VEGAFLEX level sensor.
The seals for the connection flanges and ventilation fitting (optional)
must be provided by the customer.
The seal on the measuring instrument flange (A)and the rinsing
connection (D)are already mounted ex works.
Before use,check if the seal material is resistant against the medium,
the process pressure and the process temperature.
The max.permissible pressure of the sensor is specified in the
operating instructions manual of the sensor in chapter "Technical data"
or on the type label of the sensor.
