It incorporates two valves that the probes pass through and a muffler that collects chips from the drilling process. It takes an equally short amount of installation time as the standard meters. Available on 2" through 8" flowmeters. The digital display shows the exact amount of compressed air being used, making it easy to identify costly leaks or inefficient air products. No cutting, welding, adjustments or calibration are ever required.
