An Intrinsically Pressure Insensitive Low Cost Particle Number Diluter Featuring Flow Monitoring
We present a low cost Particle Number (PN) diluter including mass flow monitoring.The device consists of a commercial hypodermic needle, a High Efficiency Particulate Air Compressor Motor Start Relay (HEPA) filter.and a custom-made flow sensor.The flow sensor is used to monitor the diluter’s performance and enable in-time replacement of the l
