AALBORG®'s VORTEX METERS for steam, liquid, and gas applications have no moving parts to wear or fail. Vortex In-line (WAFER, FLANGE. and INSERTION (fixed or retractable)mounted models need less maintenance. In addition, These units offer high accuracy throughout the flow range.
Unique dual signal processing technology independently measures each vortex, filters out non-flow noise, and increases accuracy and turndown. All
Meters are NIST traceably calibrated and individually programmed.
PRINCIPLES OF OPERATION:
Vortices are created when a fluid passes around a bluff
body as shown below. Vortices are alternately shed on each
side of the body, 180 degrees out of phase to each other,
resulting in an oscillating pressure gradient. As flow increases
the frequency of vortices increases in proportion to the
increased flow thereby creating a linear relationship.
BENEFITS:
RELIABLE: Electronics can be remote- mounted.
No fluid-to-sensor contact.
No holes to clog.
WIDE RANGEABILITY: High flow turndown ratio up to 80:1.
HIGH ACCURACY: ±0.5% of rate.
INCREASED NOISE CANCELLATION: Non-flow noise filtered out.

Racine Vortex offers high-accuracy vortex-shedding flow meters for a number of liquids and gases. The product line is quite unique: by incorporating ultrasonic technology, the meter's bluff body ("strut") has a considerably smaller footprint compared with other vortex-shedding flow meters. This results in very low pressure drop in the system. Meters are available in wafer (in-line, 1/2" to 4" size) or insertion styles (4" line size and higher). This vortex-shedding technology involves no moving parts, and the meters are virtually maintenance-free. Loop-powered gas flow meters offer HART communications, temperature compensation for mass flow measurement and gas flow standardization, CE-mark and optional ATEX hazardous area certification. Liquid flow meters also carry the CE mark.

ComfortSense
Thermal comfort measurement according to EN 13182, ISO 7736 and ASHRAE standard 113
Dantec Dynamics’ ComfortSense system is designed for research and development of heating and air conditioning systems requiring multi-point measurements of air velocity and temperature. Draught measurements require omnidirectional sensors with a frequency response of at least 2 Hz, which is fulfilled by the present system.
ComfortSense elements
The ComfortSense system consists of a main frame with anemometer circuits for up to 16 probes. The omnidirectional probes measure both air velocity and temperature. Six frames can be connected so that up to 96 probes can be monitored simultaneously. The ComfortSense main frame has a built-in A/D converter with USB 2.0 interface.
Easy-to-use
It is easy for the user to setup a measurement sequence and make a measurement grid with selection of probes from a user library. The software delivers statistical results based on user-defined measurement cycles. The ruggedly designed probes and cables are perfectly suited for large test rooms.

Specially developed for the supervision of clean-rooms, the CPE 300 is dedicated to measures of low pressure andor depression of air or neutral gases from 0/+10 Pa to -1000 /+1000 Pa.
The CPE 300 presents the advantage to become integrated perfectly into walls and to answer to the standard of cleanliness thanks to its stainless case (brushed or with lacquered).
It is equipped with 2 visual and audible alarms, with 2 reversers relays, of a big electroluminescent display and a process of autocalibration which guarantees in the time an excellent stability and a reliability of the measure in low as in high scale.
Thanks to its digital communication (RS 232 and Protocol Modbus RS 485), it offers the possibility of showing alternately (in addition of the measure of pressure) two other parameters resulting from temperature, humidity, velocity or airflow external sensors (KIMO).
Two innovative systems to facilitate the maintenance on-site :
· Its measuring element benefits from the SMART PRO system. It is individually adjusted and is automatically recognized by the device. Thanks to this process, it is possible to replace the measuring element in a simple and fast way without return of the sensor to the factory.
· The calibration in front face : this system allows to proceed to the calibration of the device without un-mounting it.
The sensor CPE 300 is so always operational !
