The ace for level measurement and interface measurement in all liquids : The VEGAFLEX 81 guided radar sensor is exceptional when it comes to measuring the level or interface of liquids. Guided radar is extremely versatile and can be found in almost every industrial sector. Whether bitumen or liquefied gas, in storage containers or standpipes, in a metering tank or in tank farms – VEGAFLEX 81 measures the level or interface (separation layers) of liquids with great reliability and accuracy. Guided radar delivers reliable measurements data for control or safety systems for

• Level measurement in ammonia storage tanks
• Level measurement in standpipes
• Interface measurement in storage tanks, bypass tubes, standpipes

Passive RFID Pressure Transponder (Series 21 D RFID) 

• Provides pressure, test point numbers, temperature and device information.
• Energy supply via RFID interface, usable for an unlimited period without maintenance.
• Comfortable read out and forwarding of measurement data.
• Extremely resistant to environmental influences and vandalism.
• Pressure Ranges from 3 to 1000 bar.

Data Logger RFID (Series 21 DC RFID) 

• Saves up to 8000 pressure-and temperature values.
• Integrated long-life battery for autonomous data logging. 
• Total Error Band ± 0,5 %FS @ 0...50 °C.

Application area : The VEGAPULS 64 is a sensor for continuous level measurement of liquids. With small tanks or in case of narrow space the small process fittings offer special advantages. The very good signal focusing enables the use in vessels with many installations such as e.g. stirrers and heating spirals.

Your benefit

• Exact measuring results independent of process conditions
• High plant availability, because wear and maintenance-free
• Maintenance-free operation through non-contact measuring principle

Function : The sensor emits a continuous radar signal through the antenna. The emitted signal is reflected by the medium and received as an echo by the antenna. The frequency difference between the emitted and received signal is proportional to the distance and depends on the filling height. The determined filling height is converted into a respective output signal and outputted as measured value.

Application area : Liquids [density: > 0.5 … 2.5 g/cm³ (0.018 … 0.09 lbs/in³)] : The VEGASWING 51 is a universal level switch with small dimensions for use in liquids. Independent of the mounting position, it detects reliably with millimetre accuracy the limit level. The instrument can be used as empty or full detector, as approved overfill protection, dry run protection or pump protection in vessels and pipelines. The VEGASWING 51 is an economical solution with maximum reliability and safety.

Function : The heart of the sensor is the vibration drive by which the tuning fork is energized to vibrate at its resonance frequency. When covered with medium, the frequency of the fork decreases. This frequency change is processed by the integrated electronics and converted into a switching command. With the tuning fork with only 38 mm length, the VEGASWING work reliably independent of the installation position in any liquid. Pressure, temperature, foam, viscosity and the composition of the liquid do not influence the switching accuracy.
