Badger Meter EPT-1XP, PEPT-1 Specifications

Electronic Unscaled Transmitter

Models PEPT-1 and EPT-1XP

DESCRIPTION

The Models PEPT-1 and EPT-1XP transmitters are two-wire electronic, high resolution pulse transmitters designed for use with the Badger Meter Disc and OP meter lines.

The unscaled pulse output is equal to 21 pulses for every revolution of the flow meter’s measuring element. A 1/2 in. OP meter with this transmitter will produce 1170 pulses for every gallon of fluid passing through the meter.

This output can be connected to almost any controller or device that has scaling capabilities and can provide 12…15V DC for operation of the transmitter. Scaling allows you to convert the unscaled pulse to standard engineering units, such as one pulse per gallon or ounce.

OPERATION

The flow of fluid through the meter causes an internal magnet to rotate. This magnet is coupled to an optical disc which is located in the transmitter housing.

The rotation of this disc is electronically sensed, producing pulses which are directly proportional to the quantity of fluid passing through the meter.

The pulses are sent to a signal processing board where they are conditioned and passed on to a controller or other scaling device. When used with the provided interface module, the amplitude of the output pulse alternates between 1.4 and 10V DC. This pulse is compatible with 12V CMOS devices such as the Badger Meter PC-100 controller.

APPLICATIONS

This transmitter will interface with any controller or flow computer with scaling capabilities that will accept a 10V DC pulse.

The transmitter can be used to provide counts to a controller in a batch operation to a counter for inventory control or to an indicator for flow rate control.
