DESCRIPTION

The Flow Dynamics automotive Body Leakage Tester (BLT) is designed to perform static body air leakage tests on vehicles

in assembly plants. This portable, self-contained unit enables automobile manufacturers to test their vehicle designs in

accordance with recognized industry standatds.

The Body Leakage Tester can determine the rate of air leakage into and out of a vehicle cabin under both pressure and vacuum

conditions. Additionally, it can be used to test body components such as doors and windows with the use of custom adapters.

All BLT units are calibrated against a primary standard air flow calibrator. This ensures a consistent, high accuracy reading during

all body leakage measurements. A calibration check ring is provided to periodically verify the accuracy of the tester.

APPLICATION

The Body Leakage Tester employs a variable-speed motor attached to a blower to produce airflow. The rate of flow is measured using

a mass air flow sensor and displayed in Standard Cubic Feet per Minute (SCFM).

With the BLT system, airflow is directed into the vehicle body via a flexible hose and window adapter. A differential pressure gage

measures the difference in pressure between the vehicle cabin and the ambient environment.

In addition to the Body Leakage Tester, Flow Dynamics

manufactures primary standard calibrators and maintains an elite calibration laboratory to calibrate all types of flowmeters.

The company’s calibration facility is NVLAP accredited (Lab Code 200668-0), meeting the highest standards for the metrology

industry as established by the U.S. National Institute of Standards and Technology (NIST).
