Application Background Printer Friendly Version
Public gas distribution utilities have a need to monitor the performance of their pipe networks to ensure the correct delivery of gas, and to ensure pressures and flows are maintained for safety and other compliance reasons.
They also need to meter gas which is sold to customers.
Oil companies have very long pipelines which traverse often very remote regions and the pressures and other parameters along these pipelines need to be monitored.
Gas networks operate different pressure and flow pipelines, in a similar way as electricity utilities have different levels of high voltage and lower voltage electricity towers and transmission systems.
Pressure sensors attached to pipelines typically have outputs in 0-5 volts or 4-20mA and these can be fed into a Neon Remote Terminal or Module and the pressure read routinely, say every 5, 10 or 15 minutes and transmitted via the cell phone (or a satellite) network to display on a Neon Server using a standard web browser.
More complex flow meters / flow computers are often installed at various points in the network and these more complex systems may have outputs and inputs using Modbus or similar RS-232-C protocols, or perhaps an interface normally used by an operator using a laptop computer locally. The flow meters can also be connected to a Neon Remote Terminal or Module and the flow information read and routinely transmitted to a Neon Server every 5, 10 or 15 minutes.
Oil and Gas Pipelines/Pressure Monitoring and Metering information is also important to keep track of, especially for high use customers. While low use customers may have a manual gas meter read quarterly by a meter reading person, high use customers typically have larger meters with pulse or other outputs every unit of gas delivered. In these circumstances, the metering pulses can be fed into a Neon Remote Terminal or Module and totaled up, so that total gas usage per day, total gas usage per hour and perhaps gas usage in peak and off peaks times can be recorded. This data can be stored locally in the Neon Remote Terminal or Module and sent to the Neon Server, perhaps daily, so that that data can be used for billing purposes.
For very remote pipelines a Neon Remote Terminal Satellite can be used to measure and report pressures at various points as it is unlikely that there would be any cellular coverage in remote areas. Such systems would be independently powered as there would be no power systems in remote areas.
Oil pipelines would typically have Rosemount or other brands of pressure and temperature sensors, usually 4-20 ma outputs at regular points along pipelines and these need to be monitored.
Oil pipelines may also have pumping stations with a full control system at regular intervals and these typically have an industrial RTU with Modbus to control that pumping station, and the Modbus could be connected via the standard RS 485 interface to a Neon Remote Terminal or Module to read the Modbus registers regularly, perhaps every 5 minutes and routinely transmit that data to a Neon Server every 5, 10 or 15 minutes.
The measured data for all of these applications would be shown on a Neon Application, using a web browser from anywhere in the world. Typically large corporations would have a higher level short term SCADA system or longer term production analysis or production optimization application which data would also be sent to, so the data could be blended into the higher level systems.
Typically this downstream processing would be done using the dynamic reporting system within the Neon Application, which provides output of any fresh data every minute, or by a customer application directly interrogating the Neon Application SQL data base
Consideration also needs to be given to hazardous area requirements. Typically oil and gas sensors needs to be intrinsic safe, so they do not cause explosions and these usually need to be connected using hazardous area barriers
