Digital Flow Meter Kit for Analog Volume TSP Air Samplers

F&J has developed Digital Flow Meter (DFM) upgrade kits for existing analog high volume air samplers.

These F&J DFM upgrade kit eliminates the need for maintenance intensive and inaccurate chart recorders and the electro-mechanical timers.

The F&J DFM upgrade kits provide greater accuracy and better data. The flow rates and volumes are automatically normalized to a reference Temperature and Pressure such as 25°C and 760mmHg. Also, the elapsed sample time is accurately measured.

A major feature is that the DFM upgrade provides automatic flow control of both brushed and brushless vacuum blowers.
