For example, new versions of Coriolis mass flowmeters now claim the ability to measure two-phase flows and to measure viscosity directly. Ultrasonic flowmeters, which now include multiple paths to provide a far more accurate measurement, are enjoying an application renaissance.
And even the lowly pressure transmitter, which remains perhaps the most widely used flow measurement device, has benefited from silicon advances. "The strongest case for the continued popularity of the pressure transmitter as a measurement device for flow and level is its reliability, says Paula Hollywood, senior analyst with Dedham, Mass-based ARC Advisory Group. "The minimal long-term drift of the current generation of transmitters may make annual calibration a thing of the past, affording users an even greater level of confidence in this age-old technology."
Coriolis Flowmeter Measures Viscosity, Too
Pro-Mass 83 I straight-tube Coriolis flowmeter provides direct viscosity measurement so that mass flow, density, temperature and viscosity can be measured with one meter. Provides tight quality control of cut points and an economical alternative to densitometers (for density measurement).
Magmeter Boasts Unique Sanitary Seal
Variflux 6000 sanitary magmeter features a unique L-shaped sealing ring with a uni-directional trapezoidal lip which, unlike regular O-rings, eliminates the problem of bacteria growth by preventing expansion of the rubber seal into the measuring tube. Ultra-smooth tube liner is made of Teflon-PFA.
Clamp-On Ultrasonic Meter in Weatherproof Enclosure
Model 101WP ultrasonic hybrid flowmeter uses either transit-time or phase-shift mode to measure flows in liquid-filled pipes sized -in. to 360-in. in diameter. Options include a pipewall thickness gauge and single or dual channel configurations.
Flowmeter Validation Package Eases FDA Audits
Micro Motion Meter Validation Package puts documentation needed for FDA audits at customer's fingertips, managing such parameters as the building number where the meter is located, meter model number, calibration documentation, configuration information and other critical data on the meters to help ease and accelerate the audit process.
Digital Vortex Meter Measures Low Flows
For stable measurements, Digital Yewflo has a digital signal processing amplifier to analyze vortex waveform spectral components and filter noise from signals. It also has an adaptive noise-suppression function and provides vibration immunity for stable, accurate measurements at low flows without any need for start-up tuning.
Digital Coriolis Meter Handles Two-Phase Flow
CFT50 Coriolis mass flow transmitter features patented signal processing technology that allows operation during two-phase flow. Capable of performing in batch applications starting with empty flow tube conditions, the CFT50 is designed to control all aspects of the Coriolis meter for precise measurement in traditionally difficult to measure batch pharmaceutical processing applications.
Non-Intrusive Fluid Detector Protects Pumps
Clear Line fluid detector mounts directly into existing pipelines between two standard 150-lb, flat-faced flanges. Without interfering with product flow, it uses RF admittance technology to detect when material is present or absent from a pipe. Relay contacts (5A DPDT) can be used to activate an alarm or switch off a pump.
Thermal Dispersion Switches Work for Flow or Level
Available in 3A-approved versions for sanity applications, Thermatel thermal dispersion switches are compact units used to detect either liquid level or flow. Optional self-test feature allows testing without removing the instrument from the pipe or vessel.
Weir-Style Diaphragm Valve Family
GSI series diaphragm valves feature Kwik-Clamp and TS series sanitary clamp and tube butt weld end connections. Series includes sterile access valves, close-coupled branch valves, tee-pattern valves, and point-of-use valves that feature a compact, patented design that eliminates deadleg areas and provides an end-to-end width that is identical to an ASME BPE 180 elbow.
