Crane Duo-Chek® Valves from Miller Energy, Inc.

Crane Duo-Chek® high performance non-slam check valves are available in the sizes, pressure classes and configurations required to meet the most demanding of applications. 

The Crane Duo-Chek® wafer valve design is generally stronger, lighter, smaller, more efficient, and less expensive than conventional swing check valves. Its design meets API 594, width is approximately one fourth the face to face dimension and is 15% to 20% the total weight, on most popular sizes, making them less expensive than a swing check valve. It is much easier to install between standard gaskets and line flanges. The savings compound during installation due to ease in handling and only one set of flange studs is required. Therefore, it is more cost-effective to install, and also to maintain.

Liquid Interface Level Measurement Using Guided Wave Radar, Magnetic Level Gauges, Float & Displacer, Thermal Dispersion, and RF Capacitance

Liquid Interface Level Measurement

The need for interface measurement arises whenever immiscible liquids - those incapable of mixing - reside within the same vessel. The lighter material rises to the top and the heavier material settles at the bottom. In oil production, for example, water or steam is used to extract oil from a well. Well fluids then route to production separators where they settle into their primary constituent parts as a water-hydrocarbon interface. Water may also be used as a transport medium or a cleaning agent and forms an interface with an allied material which is later extracted.

Knowing the position of a process interface is necessary for maintaining product quality and operations efficiency. The interface is measured and controlled by precision level switches and transmitters. Though at least 20 different types of liquid level measurement devices are in service today, only a very few are suitable for accurate and reliable interface measurement. Grouped by their operating technologies, these include Buoyancy (Floats and Displacers), RF Capacitance, Thermal Dispersion, Radar, and Redundant Technologies (those combining two measurement technologies in one instrument).

Interface Level Measurement
The five leading interface measurement technologies in use today are Guided Wave Radar, Magnetic Level Gauges, Float & Displacer, Thermal Dispersion, and RF Capacitance. These five leading interface measurement technologies in use today are discussed in the technical bulletin titled "Liquid Interface Level Measurement" and produced by Magnetrol International.

White Paper: Improving Health and Safety with Magnetic Level Indicators in Ammonia Refrigeration Applications

Magnetic Level Indicators in Ammonia Refrigeration
Anhydrous ammonia is a versatile commodity in many manufacturing applications, including cold storage and food processing facilities. In comparison, anhydrous ammonia raises a range of safety and environmental issues to be addressed when determining some form of process instrumentation. Traditionally, visual level indication of anhydrous ammonia was obtained using sight glasses. This white paper discusses key areas in the ammonia refrigeration process where magnetic level indicators (MLIs) can provide a safer , more reliable method of level measurement over conventional technologies.

The goal of this document is to highlight the benefits of MLIs that will lead to improved personnel safety , reduced risk of fugitive emissions, reduced environmental impact, and reduced maintenance costs in large commercial and industrial ammonia refrigeration systems.
