Thermal mass flowmeters-Wide Range, Inexpensive and Low Pressure Loss Model: Mass Flow Monitor
General Designed to accurately monitor and measure extreme low flows (10NL/min) of utility gases, such as air and nitrogen, a new flow monitor is available for energy saving conscious users. It is known that, over time, air leaks from air cylinders, pneumatic equipments, hose connections, etc. increase in the devices in service. This monitor accurately detects such air leaks, converts their quantity into equivalent currency in circulation, and displays it on the display to the operator to help cope efficiently with his energy saving programs. “Low price”, which is essential to a small size flowmeter for monitoring and control in energy saving applications, has come true in this small unit.
