Signature® Flow Meter Section 5 Equipment Options In order for your network administrator to identify the Signature 5.8.2 Network Firewall in the network firewall setup, it must have a node ID (also known Settings as the MAC address). This is the NODE ID printed on the eth- ernet modem’s serial tag (refer to Figure 5-32).
Signature® Flow Meter Section 5 Equipment Options 5.9 Cellular Modems Setup and data retrieval through the Signature’s web browser, as well as alarm outputs, can be accomplished remotely with one of the available cellular modems. The whip-style antenna has a magnetic mounting base.
Signature® Flow Meter Section 5 Equipment Options The Long Term Evolution (LTE) modems can automatically push 5.9.2 LTE Modem data to a secure server running ISCO Flowlink Pro software, with LTE data transmission your service parameters or provider, can be changed by replacing the removable Subscriber Information Module (SIM) card in your modem.

® Signature Flow Meter Section 6 Maintenance and Servicing 6.4 Accessing the Interior Some maintenance or servicing tasks require opening the Sig- nature housing to access the interior. Always refer to this section prior to doing so. DANGER Before opening the case, first ensure that mains power is disconnected from the unit.
® Signature Flow Meter Section 6 Maintenance and Servicing 6.5 Desiccant The inside of the flow meter housing must be kept dry at all times to prevent moisture damage to the internal components. All Signature flow meters have an internal desiccant bag to absorb moisture.
Note Teledyne ISCO recommends checking the desiccant at least every 6 months, and changing/renewing the desiccant before the entire compartment has changed color.

® Signature Flow Meter Section 6 Maintenance and Servicing Figure 6-7 Removing the external desiccant cartridge Unscrew the two black caps and carefully pour the desiccant out. If removal is difficult, screw the caps back in and unscrew again. Gently knock the caps and the cartridge against a hard surface to free any small particles in the threads, as these can hinder proper sealing and cause wear.

® Signature Flowmeter C.3 Configurations A variety of configurations can be made with Modbus, either through direct connection or through a modem. In the example shown in Figure C-1, you are direct-connecting a server PC to two individual Signature sites through Modbus, using the COM ports on the OPC Server, which are directly con- nected to the remote sites.
The definition of what data is contained and where (the reg- istry number, or address) is set by the equipment manufacturer (in this case Teledyne ISCO). RTU – Short for Remote Terminal Unit (or Remote Telemetry Unit), RTU is a code that represents data using a compact binary format.
