HR-LCD 4-20 Scaled/Unscaled Register

DESCRIPTION

The High Resolution 4-20 scaled/unscaled register (HR-LCD 4-20 scaled/unscaled) is a fully electronic, solid-state register with no moving parts. It is designed for use with all current Badger Meter® Recordall® Disc Series, Turbo Series, Compound Series, Combo Series and Fire Service meters and assemblies. These solid-state units produce a scaled/unscaled output as well as a 4-20 mA DC output signal through a dual output wire design.

High Resolution LCD Encoders, available at www.badgermeter.com.

Field Programmable: The HR-LCD 4-20 scaled/unscaled register comes standard as factory programmed, with the option for field programming the unit of measure, meter type, meter model, rate-of-flow time and units, and the analog output. Programming is performed through the IR port via a computer using the Programmer software, version 2.0.0 or greater.

Output Resolution: The output resolution table in this document lists the minimum output resolution for all Recordall meters.

Scaled Output:

• The scaled output is a switch closure output defined as: red wire = positive, black wire = negative.

• The scaled digital output from the register has a default resolution of 1/10th of the register test circle (resolution may vary in some cases).

• The movement of the meter magnet is converted to a square wave signal that is available as a scaled output through a solid-state relay.

• The scaled output is a solid-state relay to provide isolation from the 4-20 mA output.

• The nominal pulse output width is programmable from 30…100 msec.

• Resolution of the output is defined in the registration section.

• This digital pulse output is compatible with most totalizers and batch controllers.

Unscaled Output:

• The unscaled output is a switch closure output defined as: green wire = positive, black wire = negative.

• The movement of the meter magnet is converted to a square wave signal that is available as an unscaled output through a solid-state relay.

• The unscaled output is a solid state relay to provide isolation from the 4-20 mA output.

• Resolution of the output is defined in the registration section.

• The unscaled output will only be active when the device is powered by the 4-20 mA output.

• This digital pulse output is compatible with most totalizers and batch controllers.

Analog Output:

• The input pulses generated within the transmitter assembly are converted to a standard 4-20 mA control signal.

• This signal is proportional to the flow of fluid passing through the flow meter.

• Power for the device can be obtained from a 9…50V DC control loop.

• The default 20mA setting of the signal is defined in the registration section.

Mounting: The fully potted register assembly has a bayonet mount compatible with all Recordall meters. The bayonet mount positions the register in any of four orientations for visual reading convenience. The register can be removed from the meter without disrupting water service.

Magnetic Drive Communication: The register detects movement of the wet side meter magnet with magnetic sensors to provide reliable and dependable meter monitoring.

Tamper-resistant Features: Unauthorized removal of the register is inhibited by a tamper-resistant Torx® seal screw. Torx seal screws are provided. Optional proprietary tamper-proof screws are also available.

In addition, the register is resistant to magnetic tampering. The register detects any attempted tamper or register removal and displays the status indicator/alarm condition icon.

Construction: The housing of the register is constructed of an engineered polymer enclosure and a polycarbonate lens. For long-term performance, the enclosure is fully encapsulated, weatherproof, and UV-resistant to withstand harsh environments and to protect the electronics in flooded or submerged pit applications. A patented epoxy potting comprises the register bottom. Due to this unique sealing, the register exceeds all applicable requirements of AWWA Standard C707.

Wire Connections: The register is available with dual output wire connections. Both the scaled/unscaled wire and the 4-20 wire are available with flying leads for easy connection in the field.

Operating Characteristics: The register is shipped in storage mode so a meter status alarm is not triggered. In storage mode, the meter model screen is displayed. Upon sensing two revolutions of the meter magnet, the register goes into normal operation mode. The display then automatically toggles between these modes:

• 9-digit consumption displays for 50 seconds

• Rate of flow displays for 5 seconds

• Meter model displays for 5 seconds
