Pressure calibrator for gas custody transfer measurements

Smallest foundry robot in its class ABB Robotics has introduced its latest foundry robot for material handling and machine tending, the IRB 1200 Foundry Plus 2. The smallest foundry robot in its class, this compact robot can increase flexibility and reduce cycle times for precision die casting processes such as smart phone cases and other electrical components. Now protected with Foundry Plus 2, ABB’s optional protection system, the IRB 1200 can withstand harsh environments and meets the requirements of protection ratings IP66/67.The IRB 1200 Foundry Plus 2 is IP66/67 compliant frombase to wrist, meaning that the robot’s electrical compartments are sealed against liquid and solid contaminants. ABB Foundry Plus 2 robots are also unique due to their superior resistance to corrosion and capability to withstand high-pressure steam washing. “Foundry robots have long contributed to the productivity and speed of heavy-duty metal casting and automotive applications, and are now becoming

Fluke, represented by Comtest , has on offer a new ‘Ex’ Dual Range Pressure Calibrator for use in classified environments, offering ranges, accuracies and capa- bilities ideal for gas custody transfer measurements. The new Fluke 721Ex, with IECEx andAtex 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 connecting a pressure calibrator or pump to a device under test.The quick installation, without the use of tools, increases ef- ficiency, and saves time.These pressure accessories are a best-in-class set of premium hose and NoTools Required (NTR) pressure connection accessories. The rugged Fluke 721Ex Dual Range Pressure Calibrator, featuring two isolated, stainless steel, pressure sensors with accuracies 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 1.1bar or 2.48bar 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 reading simultaneously. Up to five frequently used setups can be stored. Fluke 700 Pressure CalibrationTest Kits introduce a new family of pressure connection accessories to make the difficult task of making pneumatic and hy- draulic pressure test connections easy and leak free.

increasingly important in consumer electronics applications to cast light weight metals,” says Dr. Hui Zhang, head of product management, ABB Robotics. “This robot will allow our customers to increase productivity, deliver better work piece quality and reduce cycle times.” First introduced in 2014, the IRB 1200 comes in two variants which can handle a wide range of ap- plications and are cost effective due to commonality of parts.The 700 mm reach variant can carry a pay- load of up to 7 kg, while the longer reach 900 mm variant can carry up to 5 kg of payload. The IRB 1200 is also available with Clean Room protection. Enquiries: RagnarTonnessen.Tel. +27 (0) 10 202 5787 or email ragnar.tonnessen@za.abb.com

Chemical injection on oil rigs, sub-sea drilling and fracking High-pressure processes for chemical injection systems, for example on oil drill- ing rigs or offshore platforms are a challenge for any flow measurement system. Chemicals added by injection through a bore pipe at high pressure directly at the wellhead increase water viscosity and enable efficient detachment of oil from the reservoir rock making its transport easier. In order to control the process, the in- jected chemicals must be measured accurately. Conventional volumetric systems such as gear flowmeters or turbine flowmeters cannot be used for all media due to different liquid properties and big differences in density and viscosity, and do not provide the same results in terms of accuracy and reliability. KOBOLD, represented locally by Instrotech , offered their reliable, fail-safe solu- tion, High Pressure Coriolis Flowmeters. The Coriolis Flowmeters, special forms of measuring loops, combined with special materials (different stainless steel versions, HP 160, Duplex) and heat treatment methods allow users to work with operating pressures up to 1 500 bar, extremely low flow rates from 1 kg/h and thus, offer a reliable solution for high-pressure processes.

 The Coriolis Flowmeters are highly accurate despite large differences in density and vis- cosity, reliable because they have no moving parts, and are able to measure the smallest ranges possible. Enquiries: Tel. +27 (0) 10 595 1831 or email sales@instrotech.co.za
