FLOW MEASUREMENT + INSTRUMENTATION

Highly accurate electromagnetic flow meter

• High accuracy: 0.3% of actual • Maintenance-free • No pressure drop • Numerous lining materials • Numerous electrode materials • Low-cost grounding electrode instead of earthing rings, also available in special materials e.g. Tantalum Applications The magnetic-inductive flow sensor EPS is used to measure the volume flow of liquids, slurries, pastes and other electrically con- ductive media without any pressure drop. Pressure, temperature, density and viscosity do not affect the volume measurements. Sol- id particles and small gas bubbles should be avoided.

Instrotech offers Kobold’s new electromagnetic flow meter model EPS with a standard accuracy of ± 0.3% of reading stability of zero. The new developed, micro- processor-controlled converter UMF2 guarantees high- est accuracy and is easy to operate via its alphanumeric backlit LCD terminal with six keys, plain text response, and plausibility check of entries. Empty-pipe detection, coil current monitoring, and plain text error messages guarantee full control over sensor and measuring point at any time. Pulse, status, and current outputs, as well as HART ® communication, are standard features, all of which are electrically isolated. Lining materials such as hard rubber, soft rubber, EPDM, ceramic, PTFE or PFA are available. A wide range of standard and special electrode materials is on offer, including stainless steel, Hastelloy, platinum, titanium and tantalum. The EPS is available for nominal diameter from DN10 ... DN1200 and flow velocities up to 10 m/s. An overview of EPS’s main features includes:

Introducing the ADMAGTotal Insight electromagnetic flowmeters

Photoelectric 3D level measurement and point level detection The O3D level measurement system from ifm detects solid, opaque solids and bulk materials in tanks, silos or hoppers with levels of up to 10 metres. The O3D reliably detects the load height in machinery for mechanical handling, e.g. belts, and the loading of pallets. The sensor determines level via a defined background and transmits the process value via analogue output or digitally and noise immune via the Ethernet process interface. Alternatively, the O3D may be used as a point level switch. The measuring segment of the sensor can be adapted to the shape of the respective tank. Ag- itators and other attachments can be suppressed via ‘exclusion regions’. Various container shapes such as hoppers, silos or even inclined belts, can be recognised by the sensor. This means that for bulk materials the average level is indicated, even if there are conical heaps or funnelling. Enquiries:Tel. +27 (0) 12 450 0400 or email info.za@ifm.com

Yokogawa Electric Corporation has developed the ADMAG Total Insight (TI) series, a new portfolio of electromagnetic flowmeters. The ADMAG TI series consists of the ADMAG AXG and the ADMAG AXW electromagnetic flowmeters. The AD- MAG AXG is a complete redesign of the ADMAG AXF and will accommodate bore diameters from 2.5 mm up to 500 mm, while the revamped ADMAG AXW will accommodate bore diameters ranging from 25 mm to 1800 mm. Total Insight is a Yokogawa concept for optimising operations and reducing maintenance costs through every phase of the product lifecycle. Based on this concept, Yokogawa aims to better meet its customer needs and expand its share of the electromag- netic flowmeter market. The ADMAG AXG is intended for applications that require high accuracy and high corrosion resistance, while the ADMAG AXW is for general purpose applications that mainly involve water and water-based fluids. As with the ADMAG AXF, ceramic and fluorocarbon PFA linings will be available for the wetted parts of the ADMAG AXG, for added reliability. With the revamped ADMAG AXW, fluorocarbon PTFE and natural hard rubber linings will be available. (The ability to use these linings with bore sizes between 25 and 400 mm is a Yokogawa first.) By choosing products with the optimum materials and required level of accuracy for their process, customers can reduce their CAPEX. New functions have been add- ed that will help reduce OPEX throughout the product and facility lifecycle. Enquiries: Christie Cronje.
