Advantages:
• Volume and mass measurements in any vessel shape with a freely programmable characteristic
curve
• Has a wide range of uses, e.g.
• For foam formation
• In vessels with agitators or screen fittings
• For liquid gases
• 4 to 20 mA with HART communication protocol
• Bluetooth (optional)
IT security
Endress+Hauser can only provide a warranty if the device is installed and used as described in the
Operating Instructions. The device is equipped with security mechanisms to protect it against any
inadvertent changes to the device settings. IT security measures in line with operators' security
standards and designed to provide additional protection for the device and device data transfer must
be implemented by the operators themselves.
