Safety is the number one priority for gas utilities. We can help you measure performance throughout your entire distribution network, so you can move from a reactionary “hunt and guess” environment to a proactively managed operation.
The Enetics GasComm® system provides utilities with an economical method of providing autonomous operational state monitoring of their steel pipe distribution gas network (PE pipe monitoring capability coming soon). GasComm is designed to be strategically installed at remote points throughout the distribution system to provide additional data where control functions are not required. The data acquired from these points can be used for alarming, asset condition assessment, trending, modeling, improved manpower deployment, and reporting.
What is GasComm? The Enetics GasComm system provides a way for utilities to add additional sensors to their distribution system. These additional sensors, or nodes, are a cost efficient method of expanding remote monitoring capabilities.
What is included in the GasComm system? Enetics GasComm includes the GasComm node, a battery powered Remote Telemetry Unit (RTU) with a cellular modem, and the EneticsEdgeTM User Interface.
What does GasComm monitor? Natural gas pressure, flow, temperature, water content, and vibration directly from within the distribution piping system with a single node capable of multi-attribute monitoring.
We use SCADA, so why would we need this? There are two important reasons for adding Enetics GasComm systems to your monitoring program. The first being that GasComm can be installed in parallel with existing SCADA sites to verify the SCADA data. The second reason is to extend your monitoring reach.
What do you mean when you say “extend your monitoring reach”? Installing SCADA at critical points has been the traditional method of monitoring distribution systems. However, SCADA is expensive to install and maintain, therefore non-critical points with the potential to provide data-rich information that could reduce the vulnerability of the system remain unmonitored. GasComm is the perfect solution for monitoring these system points because the GasComm system does not require external power or proprietary radio networks so the sensors and RTUs can be deployed in places where SCADA would be unrealistic due to the cost of installing power and/or communication capabilities. GasComm can affordably extend your monitoring reach and greatly enhance the safety of your natural gas distribution network.
Enetics Edge is the visual component of the GasComm monitoring system and provides a secure and intuitive web-based interface containing:
• Analytic dashboard
• Report generator
• Site status and Alarm notification engine
The software is scalable and manages data from a handful, dozens, or hundreds of GasComm monitoring systems. The combination of a SQL database and multiple output formats allows simple, well understood navigation of the data and facilitates data sharing among a wide range of users on this open platform.
1. Data Ranges: A typical month of recorded data from a buried 6-inch pipe operating at 130 PSIA during the month of September in the North East. Parameter scaling in magnitude and time are easily modified by the User. Data is also exportable in multiple formats.
2. Alarms and Events: GasComm compares live data to user-defined alarm thresholds every sample period. Upon detection of threshold exceedance for any of the measured parameters, GasComm immediately initiates cellular communications, sends SMS text messages to all identified users, and updates the analytic dashboard to visually indicate a detailed site status of the occurrence. Regardless of whether GasComm has detected an actual alarm condition or a singular event, this information is communicated immediately so the proper level of preventative or restorative measures are taken.
3. Mapping: The geo-position of all GasComm instruments in the network can be displayed on a large screen by the Enetics Edge User Interface Software. Site status is quickly determined by the corresponding icon color. Normally functioning sites appear on the map as shown in Figure 6 and change color to indicate alarm states such as pressure loss or event conditions such as low batteries or weak cellular signal strength. Hover the mouse over a particular site to view all relevant meta-data for that site such as site name, address, GPS location, reason for alarm, battery condition, etc.
The GasComm sensor array captures static pressure, bi-directional flow velocity, flow volume, mass flow, temperature, water content, and three axes of vibration data directly from within the gas distribution network piping infrastructure. The sensor array is Class 1, Division 1 certified and can be hot tap installed (Mueller or TD Williamson Toolsets) into existing gas distribution lines so no service interruptions nor special tool training are required.
The Enetics Remote Telemetry Unit (RTU) provides 6-volt DC user-replaceable battery power, data collection management, non-volatile memory storage and cellular LTE 4G data communication capability for the sensor array. The RTU is housed in a polycarbonate lockable NEMA 4X enclosure for operation in harsh environments above ground, in below-grade vaults, or direct-bury valve box applications. The RTU is programmed locally or remotely to sample, record, and transmit data at user selected intervals. Recorded data is transmitted over existing cellular networks to the assigned cloud server on a programmed schedule or in near real time response to user defined alarm condition exceedance.
