3. Install the cable and cable gland.
4. Complete the field connection wiring.
5. Connect a flow computer to the communications line on the Daniel 3818 LNG
Liquid Ultrasonic Flow Meter.
6. Repeat Step 2 through Step 5 for the Transmitter Electronics Enclosure with the
serial number tag marked with _H2.
7. Apply electrical power to the system to ensure the field connections are working
correctly. Replace the end caps and allow the system to run for the time specified
by the customer (usually one week) and an electrician have fully tested the
connections. After the Acceptance Test is witnessed and approved, seal the
conduit.
8. If required, install the security latches and wire seals on the Transmitter Electronics
Enclosure end caps (see Sealing the Transmitter Electronics Enclosure and Figure
3-8 ).
9. Install the wire seals through the socket head bolts on the Base Enclosure (see
Sealing the Transmitter Electronics Enclosure and Figure 3-9 and the junction box).
10. Ensure the safety latches are installed on the Transmitter Electronics Enclosure.
11. Set or configure the software using Daniel MeterLink. For additional installation
information refer to the system wiring diagram (see Appendix A ), Daniel MeterLink
Software for Gas and Liquid Quick Start Manual (P/N 3-9000-763). Use the Daniel
MeterLink Field Setup Wizard to complete the meter configuration. Also see, Field
Setup Wizard using Daniel MeterLink in this manual.
3.5 Wiring and I/O
Daniel MeterLink uses the TCP/IP protocol to communicate with the 3818 LNG Liquid
Ultrasonic Flow Meter electronics instead of Modbus ASCII or RTU. The TCP/IP protocol
only works across either Ethernet, RS-485 full duplex (i.e., 4-wire), or RS-232. Daniel
MeterLink can communicate with multiple meters if they are multi-dropped using 4-wire
full duplex RS-485 mode. The meter electronics is HART capable and provides
communication flexibility with Daniel 3818 LNG Liquid Ultrasonic Flow Meters.
The HART
®
output provides communication with other field devices (e.g., 475/375 Field
Communicator and AMS
™
Device Manager software) and ultimately, communicates key
diagnostic information through PlantWeb
®
architecture.
NOTICE
If not using Ethernet, a full duplex serial connection is necessary for Daniel MeterLink to
communicate with a Daniel 3818 LNG Liquid Ultrasonic Meter.
The Daniel 3818 LNG Liquid Ultrasonic Flow Meter has two 3814 electronics enclosures
and auto-detects the protocol used and automatically switches between TCP/IP, Modbus
ASCII, and Modbus RTU so it is not necessary to make any meter configuration changes to
change the protocol.
Two sets of transmitter electronics (co-located) are provided with the Daniel 3818 LNG
Liquid Ultrasonic Flow Meter. The Primary (master) electronics are in the upstream
enclosure with the serial tag marked _H1. The Secondary (slave) electronics are in the
downstream enclosure with the serial tag marked _H2.
