TurboTorch (St. Louis, MO) has introduced a new Nitrogen Flow Meter that is ideal, according to the company, for purging HVAC or refrigerator lines prior to the brazing process. The meter monitors the flow of nitrogen gas through the lines so that oxygen can be displaced. The model NFM-TT can measure gas in two ways: standard cubic feet per hour (outflow 0 to 75 SCFH), or by liters per minute (0 to 35 LPM). The meter has a durable brass body construction, a 1/4” M.F. outlet, and a 1/4” F.F. inlet. It also has an over-pressure safety release valve.
