PRESSURE + LEVEL MEASUREMENT

ROUND UP

Dual-range pressure calibrator for gas custody transfer measurements Comtest , local distributor of Fluke test and measurement tools, has introduced a new ‘Ex’ Dual Range Pressure Calibrator for use in classified environments, offering ranges,

a best-in-class set of premium hose and No Tools Required (NTR) pressure connection accessories. The rugged Fluke 721Ex Dual Range Pressure Calibrator, featuring two isolated, stainless steel, pressure sensors with ac- curacies to ±0,025% Full Scale, provides measurement of static pressure, difference in pressure and (optional) temperature of gas flow. The Fluke 721Ex is configured by choos- ing either a 1,1 bar or 2,48 bar low-pressure sensor, together with one from seven high- pressure ranges, including 6,9, 20, 24,5, 69, 103,4, 200, or 345 bar. The large backlit display will show two pressure readings and a temperature read- ing simultaneously. Up to five frequently used set-ups can be stored.

The order is fromToyo Engineering Corpora- tion, the engineering, procurement, and con- struction (EPC) contractor for this project. The new plant will have an annual output of 500 000 tons. Ethylene is a basic feedstock used in the production of many different kinds of chemicals. The construction of this ethylene plant in the U.S. is a first for a company with roots in the Japan market. To control the main production facilities at this plant,Yokogawa Solution Service will deliver the CENTUMVP integrated produc- tion control system, the ProSafe-RS safety instrumentation system, and other products. Yokogawa believes that it was able to win this order thanks to the high reliability of its products and its solid track record in delivering solutions for projects in Japan, through which it has demonstrated excellent engineering and project execution capabilities. Capitalising on its Japan expertise, large installed base, and global network, Yokogawa Solution Service is helping its customers expand their businesses outside Japan.

accuracies and capabilities ideal for gas custody transfer measurements. The new Fluke 721Ex, with IECEx and Atex Ex ia IIBT3 Gb (Zone 1) ratings, is available in 14 models and can be used with a Fluke 720RTD probe for temperature measurement. Fluke has also introduced 700 series pressure test hose and pump kits which minimise the difficulty and leaks when con- necting a pressure calibrator or pump to a device under test. The quick installation, with- out the use of tools, increases efficiency, and saves time. These pressure accessories are

Reliable gas operations with gas pressure regulator

The natural gas market, locally and abroad, shows an ever-increasing demand for operational excellence. EnergasTechnologies , leading supplier of high-end and spe- cialised equipment to the oil and gas industries in Southern Africa since 2001, has answered this need in the local context with the RMG 5020 Gas Pressure Regulator from Honeywell. In today’s natural gas industry, it is imperative for pilot-operated gas regulators to provide reliable performance in applications ranging from gas distribution systems to gas-fired power plants and processing facilities, as well as commercial and industrial gas services. As an innovative company geared to adapt its offering to clients, EnergasTechnologies carries Honeywell’s RMG 5020 gas pres- sure regulator as a solution for gas pressure reduction in municipal distribution, gas transmission as well as industrial plant applications. “The RMG 5020 also features state-of-the-art external pilot operation for accurate and safe control of outlet pres-

sure and represents the benchmark for dependable performance in this sector,” comments Laetitia Botha, Product Engineer for Energas Tech- nologies.The RMG 5020 Gas Pressure Regulator from Honeywell offers highly precise and reliable pressure reductions for a host of operations in the gas sector. With this technol- ogy designed simply for longevity, users can enjoy a range of benefits, including: a small number of moving parts; high sensitivity and accuracy; precise control of set outlet pressure; ability to handle flow variation; low maintenance requirements; and low differential pressure requirements.
