EXAIR’s Hot Tap Digital Flowmeter™ allows for installation under pressure, eliminating the need to isolate and remove pressure from the pipe it is being installed upon. 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. Hot Tap Digital Flowmeters are not a stock item and ship in three to five days. Consult the factory for NEMA 4 flowmeters.
