Control Flow Over the Web
The Universal Module controls mass flow controllers from any manufacturer over the Internet. It allows users to monitor a system of four flowmeters or flow controllers from any PC. Each flowmeter channel has a totalizer, dedicated alarm, and two dedicated relay outputs.
The module includes multi-step batch and flow control programs. All functions can be programmed through the integrated keypad using menu-driven software, or set up via RS-232 or HTML/TelNet interfaces. Cole-Parmer Instrument
Holy Orifice (Plate), Batman!
The Model 405 Conditioning Orifice Plate has four equally spaced holes that condition the flow profile for a more stable measurement and provide 0.5% accuracy with two diameters of straight pipe-run. It works with a Model 3051S transmitter and software to form a 3051SFC flowmeter. This software allows user-configured flow units, low flow cut-off, and customized process alerts. The flowmeter is suitable for gas and steam applications where a compensated flow output is required. Rosemount/Emerson
Electronic Flow Switch
The FS 10 flow switch that combines a solid-state relay and flow sensor in one compact unit measuring 1.5 x 3.55 in. It measures gas flow rates from 0.5–50 m/s and liquid flow rates from 0.01–3 m/s at temperatures from -13–212° F. When a predetermined flow rate is reached, it sends a transistor output, which can be used to turn a valve or pump on or off. E-T-A
Clamp-On Flow Meter
The Series TFXL flow meter uses time of flight ultrasonic technology to measure flow of any liquid containing less than 40% total suspended solids or aeration. It clamps on the outside of existing pipe systems ranging in size from 1/2–2 in. Outputs include 4–20 mA and a choice of simulated turbine meter or TTL-pulse frequency, allowing direct interface to data collection systems. Dynasonics
Mass Flow Meters Get Gas
Model GFM thermal mass flow meter measures the flow rate of gases with accuracy of ï€¢1.5% FS and repeatability of ï€¢0.5% FS. Readings on a LCD built into the top of the meter are in direct engineering units in terms of specific gases. Options include remote readouts via an extension wire supplied with a modular phone plug, 0-5 VDC and 4-20 mA analog outputs, and aluminum and stainless steel enclosures. Aalborg
Paddlewheel Tells Temperature, Too
FP7002 Series flow sensor has 2% FS accuracy, 4–20 mA or 1–5 VDC field-selectable output, and a NEMA-4 housing. It comes factory calibrated to match the installation fitting, and has an independent temperature sensor/transmitter with a 4–20 mA loop output scaled over a 0–100Â° C temperature range. Prices start at $365. Omega Engineering
Ultrasonic Flow Meter
This flow meter monitors flow rate and detects the fluid temperature of water in pipes that are 1 in. dia. or less. A four-digit numeric display provides water flow rate in gal/min or liters/min, total quantity accumulated in gallons or liters, and temperature in °F or °C. Outputs can be set by pushbutton for switching, pulse, or 4–20mA or 0–10 V.
Meters are available for flow ranges of 0–25.4 gpm. Prices start at $575. Ifm efector
Coriolis Flow Meter
Sitrans F C Massflo Coriolis mass flowmeter monitors mass flow, volumetric flow, density and process temperatures for liquid or gas through a pipe. Measurement is virtually unaffected by variations in pressure, temperature, density, electrical conductivity and viscosity. It communicates via HART, Profibus, Devicenet, Modbus or Can-Open. Flow meters are user-configurable in software and hardware and a uniform sensor interface enables plug and play operation. Siemens Energy & Automation
Measure Entrained Flow
Sonartrac provides on-line real-time measurement of the volumetric flow and amount of entrained air/gas present in any liquid, continuous-phase process fluid. The system also provides a measurement of only the liquid portion of the flow by compensating for the amount of entrained air/gas in the process line. The
clamp-on instrument can be installed non-intrusively on existing process lines. Cidra
Gas Flow Calibration System
The CalTrak SL-500 portable, low-maintenance flow calibrator provides a standardized accuracy of 0.4%.
It can be used for inspection, validation and recalibration of mass flow controllers, flow meters and other flow equipment in the 5 sccm to 50 slpm range. The calibrator is NIST traceable, meets ISO 17025 certification, is CE approved, and requires minimal training for flow meter verification and calibration. Sierra Instruments
