Sierra Shows AirTrak 628S At Testing Expo

Sierra Shows Its Intake Mass Flow Meter for Engine Testing

Lansing, MI – October 23, 2009 – Sierra Instruments’ Emissions Systems Division will show their Air-Trak™ Model 628S Engine Air Intake Mass Flow Meter at the Automotive Testing Expo in Novi, Michigan on October 27-29, 2009.  The Air-Trak™ Model 628S, originally designed to work specifically with Sierra’s Model BG®-3 Partial Flow Sampling System as an extremely fast, accurate, and repeatable engine air intake mass flow meter, is now offered as an excellent solution across the board in all engine testing applications.

Air-Trak™ is specifically designed to measure engine air intake mass flow rate. The meter uses Fast-Flo Sensor Technology® for an extremely fast, 200 millisecond response-time making it ideal for the toughest transient test cycles.  Integral Dual-Plate laminar flow conditioning elements and a wide 15:1 turndown make Air-Trak™ a flexible solution for the constrained piping environments commonly found in today’s engine test cells.

In addition, the versatile microprocessor-based instrument integrates the functions of flow-range adjustment, meter validation and diagnostics encased in a probe-mounted NEMA 4X (IP65) housing. Mass flow rate and totalized flow, as well as other configuration variables, are displayed on the meter’s 2 x 12 backlit LCD panel. Air-Trak™ also provides an optical/galvanic, isolated 4-20 mA output or 0-5 VDC output and two alarm outputs. The programmable transmitter is easily configured via RS 232 communications and Sierra’s Smart Interface TM WindowsTM based software or manually with three push buttons inside the instrument. Air-Trak™ is available in body sizes from 1 inch to 24 inches (316 stainless steel tubing).
