Abstract
Non-Intrusive Oil and Gas Flow Measurement in Harsh, Corrosive Environments
The FLUXUS® F705 and G705 ultrasonic liquid and gas clamp-on flow meters allow for an inherently precise bi-directional, highly dynamic flow measurement of volume and mass flow rates of virtually any gaseous and liquid media – even at low-pressurised gas lines (down to 5 bar at steel pipes), wet gas applications (up to a liquid volume fraction of 5%) or liquid media carrying high contents of solids.
With the transmitter being ATEX, IECEx Zone 2 and FM Class I, Div. 2 certified – transducers for ATEX, IECEx Zone 1 and FM Class I, Div. 1 certified are available – it is also the ideal flow meter for hazardous areas. Moreover, with its stainless steel enclosure (316 L/1.4404), it is highly corrosion resistant and especially suited for applications offshore.
As the ultrasonic transducers are mounted on the outside of the pipe wall, enclosed in the rugged stainless steel VARIOFIX® mounting fixture, the system is independent from the internal pressurisation, does not suffer from wear, tear or clogging, can’t be a risk for leaks and does not cause any process interruptions for installation.
Even extreme temperatures from as low as −190 °C up to 600 °C aren’t a match for FLEXIM
Cropico’s Low Resistance Measurement Guide in New A5 Format
Cropico’s popular illustrative guide providing an overview of low-resistance measurement techniques, common causes of errors and advice on how to avoid them is now available in a handy A5 format.
The free, 34-page colour ‘Guide to Low Resistance Measurement’ (http://www.seaward.co.uk/resistance) features tables of wire and cable characteristics, temperature coefficients and formulae to enable the user to select the appropriate measuring instrument and measurement technique.
It includes a helpful section explaining the role and importance of resistance measurement in the manufacture of electronic components, switches, relays, connectors cabling, electric motor and generators and fuses. Information on resistance measurement requirements in the automotive and railway utilities industries has also been featured.
There’s a useful ‘Glossary of Terms’ at the end of the guide, providing an easy-to-follow explanation of items relating to both bonding and earth resistance, as well as common industry acronyms such as digital multi-meter (DMM), device under test (DUT) and American wire gauge (AWG).
A copy of the guide is available from Cropico (part of the Seaward Group).
