Profile - Velocity Data Logger

Profile - Velocity Data Logger Overview

The Profile - Velocity Data Logger calculates the flue gas velocity by measuring the temperature and differential pressure in a flowing air or gas stream. It also measures the ambient pressure and temperature and logs all the data recorded on a point-by-point basis.

The Profile not only reads and data logs the temperature and differential pressure of each traverse point - along with ambient temperature and pressure - but can display them as a graph on the screen giving an instant picture of velocity and whether it is suitable for isokinetic sampling.

APPLICATIONS

• Determines stack velocity for U.S. EPA, ISO, BS and CEN standards
• Heating & ventilation (HVAC) set-up and service
• Isokinetic particulate sampling
• Industrial processes including environmental efficiency and cost saving through production control

Profile - Velocity Data Logger Design

The Profile will log up to 21 separate tests and store the point-by-point sample information for up to 4 traverses per test, along with the averages for each traverse. Once collected the information can be displayed on the Profile screen or downloaded to a PC for data processing and report generation.

Data can be retrived from the Profiles huge memory directly to your computer via a serial port and utility such as Hyper Terminal. Parameters are comma delimited and CR line terminated so they are suitable for spreadsheet applications.
