Hot Stuff for the Automation Market | products & resources INTECH MARCH/APRIL 2019 47 Coriolis mass flowmeter The Promass A flowmeter measures substances drop for drop. The flow- meter measures values with repeat- ability, even in cases where process and ambient conditions fluctuate. The measuring device is suited for installation, for example, in modu- lar process facilities and skids. The sensor system is mounted on a base plate that acts as a "shock absorber," effectively shielding the Coriolis measurement from out- side interference, such as from pipe vibrations. Other contributing factors are the oscillation frequency of the measuring tube and its completely balanced oscillation behavior. At a specified maximum measured error of ±0.1 percent, high-precision measurements down to 8 g/min are possible, or—if the maximum error is permitted to be ±1 percent—even a quantity of less than 1 g/min can be measured. Because of the variety of device options, such as nominal diam- eter, material, process connection, certification, transmitter type, or degree of protection, Promass A can be used in numerous ap - plications. It is a small measuring device with a nominal diameter DN 1 (1/24"), so the flowmeter can also be installed in extremely tight spaces, such as in skids. A multitude of process connections are available, such as flanges, lap joint flanges, couplings, internal threads or Tri-Clamps. The flowmeter can be used at process tem - peratures between –50 and +205°C (–58 and +401°F). Endress+Hauser, www.us.endress.com Process flowmeter The Rosemount 9295 helps end users streamline procurement, installation, operation, and maintenance. Design and purchasing consists of specifying and buying one assembly. Most field welding, cutting, fabrication, and other tasks are not required, because all com- ponents are fully assembled and leak checked. The Rosemount 9295 is a sin- gle assembly, but individual components can be replaced while it is in service. This integrated DP flowmeter assem- bly withstands the challenging environ- ments and piping requirements found in refineries, chemical processing, and other heavy industrial plants. The device also has a welded spool section for drop-in installation, an all-welded design that meets piping requirements for hydrocar- bon applications, roddable impulse lines for removal of impulse line blockages without shutting down the process, optional inte- gral RTD for critical temperature reading to assist mass flow calcu- lations, dual-tap configurations that support fully redundant DP transmitter assemblies for safety instrumented systems, and isola- tion valves that meet API 602 requirements and are designed to operate through years of continuous service. The flowmeter uses the Rosemount 3051S DP transmitter to deliver flow readings and device diagnostic information via HART. Emerson, www.emerson.com Laminar flow sensor The EE660, designed for laminar flow monitoring and clean room applications, measures low air velocity. The transmitter is now also available with an RS485 interface. The EE660 is suitable for mea- surement of low air velocity down to 0.15 m/s (30 ft/min). It features an E+E hot film sensing element. Furthermore, the sensing element is resistant to contamination and has a low angular dependency. In addition to current and voltage outputs, the device now has an RS485 interface with Modbus RTU or BACnet MS/TP protocol, which allows for integration into a bus system. The EE660 is avail- able for duct mount or with remote probe. The enclosure with ex- ternal mounting holes facilitates installation with a closed cover. The measured data is also available on the optional display. Backlight and 180° rotatability allow reading in any mounting conditions. The EE660 is user configurable with jumpers on the electronics board or via software. The adjustment and the display setup can be performed with an optional configuration adapter and the free EE-PCS product configuration software. E+E Elektronik, www.epluse.com/en Flow sensors The company's flow switches alert users to potential failures due to a reduction in neces- sary fluid flow. The recently released BFF series of flow sen- sors, which are available in both thread-in and inline versions, provide a switching output that is activated when the flow falls below a user-defined rate. This makes it possible to notify users of system problems, such as the failure of a pumping system, a clogged filter, or leaks, before they cause critical issues or system shutdowns. The completely solid-state calorimetric sensing technology measures temperature differential on each side of the sensing probe and has no moving parts. They are resistant to failures caused by dirt or foreign object buildup. The devices also have continual flow monitoring and visual display of flow with inte- grated light-emitting diodes. The BFF series of flow sensors complement the company's ex- isting line of temperature sensors and are an addition to the line of process-oriented sensor products. Balluff, www.balluff.com
