It is used to remotely monitor the level of the contents of a tank. The tank level and additional event and status information are reported to the WESROC RMS Host System (Host) at scheduled intervals. In addition, the CTM will report to the Host immediately to track tank events in real time. The CTM uses the GSM cellular network and the internet to transport this information. Communication with the Host is bi directional which allows for remote configuration of the CTM should the tank monitoring requirements change or in the event that the CTM is moved to another site. The CTM also provides a local tank level display capability. The CTM can be configured to send short range radio data packets to a nearby WESROC RMS Base Unit (Base Unit). Once initialized to the CTM, the Base Unit will provide the customer with a local display of tank level for up to eight tanks (depending on which Base Unit is used). The EUT contains a pre-approved transmitter (FCC ID: N7NWISM0228). It is a GSM Quad-band cellular module with modular approval. EUT Received Date: 8 June 2011 EUT Tested Date: 8 June 2011 NOTE: 1.
