PRODUCT DESCRIPTION
The ER-9 is an external or battery powered indicator that displays rate of flow and total flow . The ER-9 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…28V DC) power supply .
A single unit can accept NPN or dry contact inputs for low or high speed applications .
The ER-9 is powered by two replaceable 3V Lithium batteries . You can install a new battery 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 the battery life .
The unit operates in battery mode for at least six months . To extend battery life to five years, connect the unit 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 .
