New in-line viscometers
This new FVM model viscometer is pressure-resistant, explosionproof, and operates in temperatures to 280° C.
The in-line viscometers provide accuracy and reliability for measuring process liquid viscosity. These oscillation viscometers utilize a piezoelectric ceramic sensor and report viscosity at ± l% accuracy.

New diffuser helps reactor performance
A new product is designed to improve fixed bed catalytic reactor performance by the application of flow conditioning technology to optimize feed distribution at the inlet of elliptical head reactors.
Increases in capacity, efficiency, and extended equipment life are achieved, the company says, when the working fluid is uniformly supplied to the active or operational part of the reactor. The elliptical head diffuser (EHD) is specifically designed for reactors that are prone to poor flow distribution because of high ratios of vessel diameter to length of expansion. It provides a flat velocity profile to the top of the catalyst bed.
The EHD can be installed and removed through a reactor inlet nozzle or fixed in place within the head. Each of its component sections distributes flow toward an equivalent area of catalyst while balancing momentum of each fluid substream.
Benefits of the EHD include increased reactor residence time, full use of the catalyst, elimination of surface fluidization of catalyst and attrition, and reduced system pressure drop by elimination of perforated plate distributors.
It is suited for use in flow conditioning of gaseous feeds to reactors for production of organic and inorganic chemicals. Other applications being developed are for liquid feeds in refining and petrochemical processes.

Free catalog on repair products, coatings
A new catalog, yours free upon request, describes a complete line of repair products and coatings for plant and equipment maintenance and overhaul. Products help reduce maintenance, repair, and replacement costs and can be applied by in-house personnel with minimal training. The catalog also includes a full family of adhesives for bonding and assembly.
The new catalog describes epoxy, urethane, and methacrylate-based products for repairing metal, rubber, concrete, and other surfaces; coatings for protecting equipment exposed to abrasion, corrosion, and chemicals; and emergency-repair adhesives that allow damaged equipment to be returned to service in minutes. Specific lines include Wear Guard abrasion-resistant products designed to extend the life of critical process equipment and Floor Savers epoxy flooring products for maintenance, repair, and resurfacing. The company's line of adhesives for bonding and assembly includes flexible, high-strength epoxy adhesives; methacrylate adhesives for bonding engineered plastics, advanced composites, and exotic metals; SUPERLOCK threadlocking adhesives; Zip Grip instant cyanoacrylate adhesives; and a selection of silicone sealants. The catalog also includes Flexane castable urethanes for making flexible molds and nonscratching holding fixtures.

New ultrasonic flowmeters
A new line of ultrasonic flowmeters is designed for compressed air, nitrogen, and other industrial gases.
Designed for use in 2, 3, 4, and 6-in. ANSI lines, these ultrasonic meters help users quantify compressed-air use to immediately recognize losses or leakage, eliminate unnecessary compressor maintenance, and adjust volume to consumption requirements.
Meters are easy to install, maintenance free, and have virtually zero-pressure drop. Units respond immediately to changing loads, displaying flow rate and totalized volume.
