Bridle, Bypass Chamber and MLI measurement systems
The comprehensive range of bypass chambers and Magnetic Level Indicator (MLI) options from VEGA provide an easy solution for measurements with our class leading Guided Wave Radar (TDR / GWR) transmitter, VEGAFLEX.
VEGAFLEX offers unrivalled performance and sensitivity for level measurement, interface monitoring and process control across a broad spectrum of industries. Simple to setup and easy to maintain using asset management tools, like NE107, as well as integrated diagnostics and event memory. Also featuring optional Bluetooth operation via smartphone, tablet or PC.
Chambers range from standard designs with fast lead times, to fully bespoke systems meeting specific process requirements and custom specifications / materials, to offer you the complete solution.
We engineer and supply packages for both AD2000 and ASME design codes, as well as carrying out all types of testing, inspection and specialist packaging and crates for shipping.
Bridles & Bypass Chambers
VEGAPASS 81, offer easy specification and fast delivery for straight forward chambers to both ASME and AD2000 design codes.
Bespoke chambers, designed to your exact requirement and to meet the harshest standards and conditions whether just a bypass chamber or dual bypass/MLI solutions.
VEGAPASS series bridle utilises a chamber mounted directly to the process vessel with two or more process connections. The connections are the inlet and outlet that allow the liquid level in the chamber to match the level in the process vessel. The VEGAPASS incorporates a VEGAFLEX Guided Wave Radar that measures the process level.
Magnetic Level Indicators (MLI) and combination sytems
As a sight glass replacement solution, MLI’s provide a clear indication of process level and compliment our GWR transmitter range.
VEGA provide stand alone designs or combined MLI/GWR chambers.
The VEGAMAG series MLI uses a chamber that houses a sealed float with a circular magnetic array. A visual indicator, containing a series of magnetised flags, mounts external to the chamber. As the process liquid fills the chamber the liquid lifts the float, which rotates the flags from white to red, giving a visual indication of the liquid level inside the vessel.
To solve the high maintenance cost of displacers, our VEGAFLEX Guided Wave Radar’s can be supplied complete with special mating flange options to suit existing displacer chambers (or cages). This means you can retain the chamber and just replace the top transmitter with a low maintenance radar-based measurement device. Easy, simple and quick!
We can also offer a complete chamber replacement design service and free site visits to help identify mating flange sizes and requirements.
As with process and sight gauges, a large number of displacer level gauges require a significant amount of maintenance to keep them operational. By utilising a Guided Wave Radar transmitter to retrofit to existing vessel connections, it replaces displacer technology that can be prone to mechanical failure, also greatly reducing regular maintenance and potential downtime.

Level measurement and point level detection in the steam drum
Process heat in a power plant is provided by steam at different pressures. The required process temperature is regulated via the steam pressure. Depending on the process temperatures there can be pressures up to 160 bar, at temperatures up to 400 °C in the steam drums. Reliable control of water levels and fail safe limit of high and low water in the steam vessels are crucial for the safe operation of the plant.
Reliable measurement through automatic measurement correction
Optimal operation of the facility
Simple mounting and setup
Level and pressure measurement in an oil separator
The separator vessel contains a mixture of crude oil, gas, water and sand extracted from the subsea well. Precise monitoring of these multiple separation interfaces and emulsions play a vital role in ensuring the quality of the oil separator for separation. Exact control of interfaces, level and pressure allows optimum utilization of the oil separator and increases the effectiveness of the entire asset.
Measurement results are unaffected by process conditions
Efficient operation and high oil quality
Gas separators (scrubbers)
Level and pressure measurement in the gas separator
Extracted natural gas and gas residues from oil production are contaminated with water and are therefore collected in gas separators (scrubbers) for separation. Pressures of up to +150 bar keep the gas in the liquid state. Exact pressure and level measurement enable optimal utilization of the gas separator and effective control of the gas drying process. The separation of gas from water is carried out by chemically binding the water to glycol and separating it mechanically. Accurate measurement of the gas/water interface determines the quality of the gas.
Reliable measurement, independent of process conditions
Ensures an effective gas drying process, and thus high quality gas
Level and pressure measurement in the distillation of primary products
The process temperatures in a distillation column place high demands on the measurement technologies deployed. The boiling point of the distillate frequently exceeds 400 °C. The aim is to achieve the highest possible product throughput for cost-effective operation of the plant. This means the raw material replenishments need to be optimally controlled by level and process pressure measurement in the column.
Reliable level measurement across all pressure and temperature ranges
Standardized operation in all the measuring principles
Robust and maintenance-free sensors reduce maintenance overhead
