Good alternatives to mechanical meters

Increase safety, reliability & reduce maintenance costs

When first installed, mechanical meters work fine. But when assets are aging and the technology has reached its limits, maintenance costs rise. Precious time is spent on installed instruments' maintenance. By depending on the imperfections of the mechanical meter, your process remains stable. However, a break can lead to a complete production shutdown resulting in money lost and reduced safety and reliability. Replacing your aging technology is therefore key to avoid such a scenario.

Distillation column

All major processes in refinery are based on the heating and partial evaporation of hydro-carbons. Maximizing the feed rate of the crude distillation column while ensuring the mixture of crude types meets environmental specifications is a must. Modernizing your level measurement technologies can avoid costly shut downs. Guided wave radar (Levelflex) is your reliable alternative to displacers (compliance with API2350 – functional safety) as it is not affected by density and temperature changes.

Vacuum distillation

Varying ambient temperatures in vacuum distillation often jeopardize measurement reliability. The mechanical and thermal impacts destroy the capillaries every 4-6 months. Avoid downtimes, due to faulty measurement, with a reliable technology like electronic DP. Process safety risks are then minimized due to architecture and design.

Storage tanks

Floats are very often used in level applications because of their costs. Nevertheless, their reliability is affected by density variations, and they are prone to build-up over time which causes inaccurate or no (jamming/ blocking) measurement. This leads to high maintenance costs due to needed regular cleaning and dismantling, and proof testing is therefore time consuming and made difficult. Replace your floats with vibronic limit switches and gain in availability and safety.

  • Less time spent in maintenance, checking and cleaning

  • Self-monitoring device with SIL3 capabilities (compliance with API 2350)

  • Proof testing intervals up to 12 years

Fuel transfer

Existing flow meter technologies such as positive displacement (PD), turbine, variable area (VA or Rotameter) and differential pressure (DP) - once the best-fit or only solution for some applications - are no longer the only choice. Today, modern flow technologies such as vortex, ultrasonic and Coriolis offer a much more reliable alternative, especially when a plant's process needs improvement.

  • Intrinsic safe

  • Cost savings in respect of cabling work

  • Superior performance and less maintenance

  • Direct mass flow measurement
