Type BA
Level- and interface metering
- Level- and interface metering
- Limit switches
- Electronic transmitter
- Special materials
- Surge pipe for harsh operating conditions (optional)
- High temperature design (max. 250°)
The BA-type liquid level meter is suitable for level measurement of liquid products in open or pressurized vessels. The device is based on Archimedes’ buoyancy principle.
Applications
- Level measurement, monitoring, regulation and control.
- Especially because of its design, the BA is suitable for processes under difficult and rough operating conditions.
- For process monitoring and regulation, the units are available with additional electrical equipment.
Special features
- Wide range of wetted materials
- High pressure design
- Clear 90°-scale
- Stainless steel display
- Can be used in the Category 2 potentially explosive area
