Industrial Registers

Model ER-9 and ER-9/R (Remote) Digital Resettable Totalizer

DESCRIPTION

The Badger Meter® Model ER-9 register is a meter-mounted totalizer and rate indicator with scaled pulse output designed for use with all meters in the Badger Meter product line.

The ER-9/R is the remote version and can be used with any Badger Meter flow meter that is equipped with a compatible pulse endpoint. A rear adapter plate is provided with the remote version for attachment to a wall or other suitable surface.

The unit is battery powered with two lithium batteries. Optical sensors and other electronic sensors with open collector outputs must be externally powered.

The totalizing function uses an easy-to-read, 8-digit numeric LCD display. The rate mode uses a similar 4-digit display. Step-by-step independent programming of scale factors for the rate and totalization functions allows you to program any engineering unit such as gallons per minute and total gallons. The scaled pulse output has its own independent scaler.

When the indicator is used as a totalizer, the display can be reset to zero from the front panel button or from an external switch wired directly to a rear terminal. The front panel Reset function can be inhibited.

You can backlight the display by connecting a DC power source to the unit.

When the battery is low, an indicator appears on the screen several weeks before the end of the battery life to remind the operator that the battery is in need of replacement. The unit operates off the batteries for a minimum of 6 months when using pulse output. When connected to a DC power source, the back-up battery life is 5 years.

FEATURES

• All solid-state components for long life

• Battery powered

• Low battery indicator

• Corrosion-resistant plastic housing built to NEMA 4X specifications

• Programmable for rate of flow and totalization

• Backlit display available

• Front panel totalizer Reset function can be disabled

• Reprogramming can be inhibited

OPERATION

Fluid flowing through the meter causes pulses to be generated by the sensor. Each pulse represents a specific fluid volume. Example: the Model 25 Disc meter generates 198 pulses for every gallon of fluid passing through the meter. Using a scale factor, the pulse indication on the display will be changed to a meaningful unit of measure.
