PD2-6200 Helios Analog Input Flow Rate/Totalizer

Brand: Precision Digital Corporation

Go with the Helios PD2-6200 when you want to display both flow rate and total at the same time from a pulse output flowmeter. 

The PD2-6200 can display both flow rate and total in six full digits and can also be configured to display non-resettable grand total. 

The PD2-6200's NEMA 4X, IP65 rated field mountable enclosure, super bright LEDs, and wide operating temperature range make it perfect for outdoor applications.
