Mechanical

Housing and Keypad

The Register housing and bases are aluminum castings that are powder-coated with high durability, urethane powder. The cover internal hinge design provides easy access to the internal connections and keeps all moving hinge parts out of the elements to further prevent corrosion. Weights and Measures features are accessible by using a seal-able fastener on the side of the cover.

Alphanumeric Keypad

The Register alphanumeric keypad is made of petroleum resistant silicone and consists of 12 large alpha-numeric keys, 5 navigation keys, and 5 function keys that relate to the adjacent display indicators for operator-guided functionality. The keys, when pressed, give the operator a tactile, positive confirmation of keystrokes. The keypad multi-tap functionality also allows users to input up to four alpha-numeric characters on a single key.

Electrical

Inputs

Inputs are configurable in the Register to handle a variety of external accessories that provide data signals in the metering system including pulse input and a variety of external sensors.

•Voltage – 9 to 28 VDC

•Current maximum: 5 A maximum

Pulse Input

In order to calculate flow measurements when mounted to a positive displacement meter, the Register receives a pulse input from a quadrature pulser that is mechanically connected to the flow meter output shaft (meter mount option only). A pulse input can also come from an external device such as a Liquid Controls Pulse Output Device (POD) or another externally mounted pulse generator. If an external LC POD is purchased, these materials are necessary, but are not supplied with the POD:

•16-22 AWG 4 conductor Shielded Cable (Consult the POD manual for complete specifications)

•Weather Proof flexible conduit or loom

•½” Conduit connectors or cable glands

RTD Temperature Probe

The Register is equipped with an input for a temperature probe, so the register can read realtime temperature as well as compensate volume measurements according to the temperature of the product.

•4 wire platinum sensor

•100 Ω resistance at 0 ºC

•138.5 Ω resistance at 100 ºC

Optical Air Eliminator

The Register is equipped to handle an optical air eliminator input:

•Voltage – 10 to 28 VDC

•Current – 0.5 Amp maximum

Digital Inputs 1, 2, 3, 4, 5, and 6

•Active Low, normally pulled high

•Voltage: 5 to 28 VDC

•Current: 3 mA maximum sink current
