The ER-9 is an external or battery powered indicator that displays rate
of flow and total flow. It also has a scalable pulse output. It has
independent programmable scale factors for rate and totalization,
allowing you to program these displayed values in different but
meaningful engineering units, such as gallons per minute and total
gallons.
The supertwist LCD display with 8 digits for total, and 4 digits plus
legend for rate, provides easy viewing at a glance. For conditions
where ambient light is poor, the display can be backlit by connecting
an external DC (10-28 VDC) power supply. A single unit can accept
NPN or dry contact inputs for low or high speed applications.

Powered by two replaceable 3V Lithium batteries, this unique design
allows for a new battery to be installed before removing the old one,
thereby retaining count total and program data. A low battery indicator
appears on the screen to provide a warning a couple of weeks before
the end of battery life.
The unit will operate in battery mode for at least six months. To extend
battery life to five years the unit must be connected to an external DC
power source.
Setup is quick and easy as the two front panel keys are used to scroll
through and preset values in all program mode choices.
This Product Contains Lithium Batteries.
