The ADMAG AXW™ series of magnetic flow meters has been developed based on Yokogawa's decades of experience in the design and manufacture of magnetic flowmeters. The AXW series continues the tradition of high quality and reliability that has become synonymous with the Yokogawa name.

The AXW series is ideal for industrial process lines, and water supply and sewage applications. With outstanding reliability and ease of operation, developed on decades of field-proven experience, the AXW will increase user benefits while reducing total cost of ownership.

Magnetic flow meters, also called electromagnetic flow meters or "magmeters", operate on a very simple principal. An electrically conductive liquid moving through a magnetic field will generate a voltage that is related to the velocity of the liquid. Magnetic flow meters have no moving parts and present little to no pressure drop to the piping system into which they are installed.

Sizes are available from 500 to 1800 mm (20 to 72 inch.) with a wide liner selection such as PTFE, natural hard rubber, natural soft rubber, and polyurethane rubber. The line accommodates industry standard process connections such as ASME, AWWA, EN, JIS, and AS flange standards. A submersible version is also available.

Care and maintenance for magnetic flow measurement devices is simple and minimal. The manual included below provides basic guidelines for maintenance procedures of ADMAG TI (Total Insight) Series AXW magnetic flowmeters.

White Paper About Safety Compliance for Solenoid Valves

Solenoid valves for industrial process control applications

Regulatory modifications have raised important issues in design and use of industrial safety systems. Certain changes in IEC 61508, now being widely implemented, mean that designers and users who desire full compliance must give new consideration to topics such as SIL levels and the transition to new methodologies.

In particular, these issues can impact the selection of solenoid valves and prepackaged redundant control systems (RCS) for implementation in a safety instrumented system (SIS). Such selections may also be affected by how experienced valve suppliers are at dealing with complex new compliance methodologies.

These issues are especially applicable to the oil, gas, chemical, and power industries - in applications such as safety shutdown systems, boilers, furnaces, high-integrity protection systems (HIPS), and more. These issues are of concern to safety engineers and reliability engineers, as well as to process engineers, engineering executives, and plant managers.

This report, a white paper made available by ASCO Valve, will address these issues in developing a compliant safety instrumented system using valves and redundant control systems. Making the right choices in safety system planning and in valve supplier selection can affect design time, costs, and effort — as well as the safety of the plant itself.

The Eclipse Model 706 is Magnetrol's loop powered high performance guided wave radar level transmitter. It incorporates many of the company's latest innovations into a single instrument capable of meeting the demanding requirements of an array of industrial applications.

Product improvements include increased signal to noise ratio, suitability for use with low dielectric media, and the ability to deliver accurate indication under foaming, flashing, or other challenging conditions. An extended probe offering enables use in measuring interface, liquified gas, even bulk solids.

The instrument is suitable for overfill applications, and does not use algorithms to infer measurements in a dead zone that may occur near the top of the probe in some other designs. The Eclipse 706 delivers true measurement right up to the process flange. Upgraded electronics allow the unit to be pre-configured prior to shipment, if requested. Additionally, the widest range of communications options is available.

Tips For Best Control of Low Flow Rates

Coriolis mass flow measurement is the method of choice for applications requiring best accuracy under very low flow conditions. The Quantim Series of mass flow controllers from Brooks Instrument provide indication of fluid flow, density and temperature for applications down to 0.001 Kg/hr. The instrument, in addition to a Coriolis flow sensor, provides digital signal processing, an integral or close coupled control valve, and PID control to deliver a total flow control solution in an integrated package.

Obtaining best available performance on a consistent basis is supported by a well done installation.

  • Mount the instrument to a stable surface free from excessive mechanical shock and vibration that might impact performance.
  • Locate the device where it can be easily accessed or removed.
  • Install an appropriate filter on the fluid inlet side.
  • Provide a positive shutoff valve on the downstream side to enable zeroing after installation.
  • Make sure the process flow direction matches the required flow direction of the instrument.
The sensor and control valve are designed to function properly when filled with process fluid. This means your installation cannot deliver entrapped gas in a liquid or liquid droplets in a gas. If compressed gas is used to force dosing fluids through a system, it may be necessary to provide a degassing arrangement upstream of the flow controller. Dissolved gas that flashes due to a pressure drop through the instrument can form bubbles that distort sensor and valve performance. 

Little to no maintenance is required after the instrument is installed and zeroed. The inlet filter should be changed at intervals sufficient to assure delivery of clean process fluid to the instrument.

More technical detail on the Quantim Coriolis flow measurement and control instruments is provided in the document below. Whatever your flow measurement or control application, share your challenge with measurement and control specialists, combining your own knowledge and experience with their product application expertise to leverage an effective solution.
