Use this flowmeter to monitor seal leakage in gas compressors

| By Mary Page Bailey and Gerald Ondrey

The ST75 mass flowmeter (photo) provides precision measurement in small lines for the detection of hazardous, non-compliant and costly gas leaks, including the monitoring of seal leakage from gas compressors. It measures air or gases from 0.01 to 559 std. ft3/min depending on line size and actual process conditions. The ST75 is factory-calibrated and can provide a flow turndown range up to 100:1. With built-in temperature compensation, the ST75 offers highly repeatable performance in harsh industrial process environments. It features accuracy to±2% of reading with±0.5% repeatability over varying process temperatures and pressures in line sizes from 0.25 to 2 in. — Fluid Components International LLC (FCI), San Marcos, Calif.
