The meters are specifically designed for displaying flow rate and total from flowmeters with analog or pulse outputs. 
These flow rate/totalizers are particularly well-suited for flow applications because they can display flow rate and flow total at the same time, provide power to drive the flowmeter, and display flow total, flow grand total, or non-resettable flow total on up to nine digits.
