Benefits of certified flow controllers

Liquid Automation Systems supplies a versatile range of flow controllers to cater for process and custody transfer flow as well as batch controller applications.

Most country’s Weights and Measures Departments requires the use of certified custody transfer systems when such systems are used for trade. Some countries like South Africa requires additional local approval over and above international approval like OIML. If specified that a system needs to be used for trade LAS will supply a system approved internationally and if in South Africa also with local certification. Should a system be bespoke then LAS will undertake all actions required to have it certified locally. If outside South Africa, LAS will provide the international approval documents for acceptance or for local certification in such a country.

Custody transfer applications include batch controllers that include additive control and blending that is typically used for petroleum loading gantry operations and flow totalizers typically utilised for pipeline transfer applications.

The flow controller is a device used to measure and control the flow of liquids and gases through a specific design and calibrated control system, which depends on the project requirements and industrial constraints.

The benefits of certified flow controllers include advancement in flow-signal processing, highly stable flow control regime that processes the fluctuations in process control and flow. In addition to this, there is significantly reduced power consumption.

Dynamic changes are produced with the flow controller because it can be adjusted through speed settings. There are also signal options and communication outputs that can be modified by the engineer for optimised operation and accuracy. The functionality of adjusting the flow rate by the engineer also increases the safety of operation.

In addition to Custody Transfer certification a metering system may need to comply to specific electrical regulatory requirements – dependent on the conditions in which it is intended to be used. LAS supplies equipment with international as well as local South African certification to cater for all common Zones (0, 1 &2) and gas groups applicable for hazardous substances to be measured. As mandatory all equipment supplied in South Africa by LAS is Locally Certified at no cost to clients.
