Current Schneider Electric Test Fixture: - High rate of out-of-calibration flow meters. - Difficult to remove. - Ideal fixture would use standardize equipment that can be interchanged when one piece is out for calibration. Selected Digital Flow Meter

Fixture Concept 1 Fixture Concept 2 Fixture Concept 3

After selecting the digital flow meter, we designed several different test fixture concepts. Concept 1: simply replace the analog meter with the new digital meter. Concept 2: similar to concept 1, with a quick disconnect feature. Concept 3: flow meter is attached to a portable, stand alone fixture.

Flow Meter Data

New digital flow meter with Schneider Electric test stand. - Analog meter was disconnected. - Digital flow meter achieves similar results as the current meters.

Portable stand allows flow meter to be used on any test fixture.

Work instructions created for quick and easy set-up. - Demonstrates how to program multiply flow ranges. - Set Min./Max. alarms for flow verification.

Digital Flow Meter Project

Spreadsheet 1: shows the flow range in similar units for several product lines. Spreadsheet 2: shows cost estimates for flow meter and updated test fixture. Spreadsheet 3: shows the calculated flow ranges for every pneumatic product using the new flow meter.
