The majority of utilities today have assets in the field that are not being monitored on a regular basis, or perhaps not at all, due to budget or staffing issues. Several common examples are discussed below that can be remedied quickly, easily, and affordably using Remote Monitoring Solutions from Enetics.
CIRCULAR CHARTS: There are thousands of circular charts still in use today and their shortcoming are well understood. The manpower required to collect paper charts and replace batteries is excessive and not at all efficient, the data obtained is subject to interpretation, requires human translation, and alarm conditions at the site may not be recognized for weeks.
The Enetics GasPoint RTU is an ideal solution. GasPoint can be operated in parallel with existing circular charts or operate as an ideal replacement for the chart approach. GasPoint is IP-67 packaged, connects to existing site feed lines using simple Swagelok fittings and has a five year battery life.
Highly accurate pressure and temperature data are digitized, recorded in non-volatile flash memory and periodically transmitted to secure cloud-based data servers using encrypted cellular telemetry. Every sample is examined for alarm conditions and users are immediatly notified via email and/or SMS text messages of any problems at the site. For more information, see the application note below:

SLAM SHUT VALVES: Most utilities need to maintain a routine inspection schedule of their slam shut valves to determine if there has been activation or not. The complexity of network design may not allow simple pressure monitoring at the SCADA points to reveal that a slam shut valve has triggered.
To alleviate the need for these routine site inspections, Enetics has introduced the GasTrack RTU, which can monitor two pressure channels and the state of a slam shut valve without any power drops or radio network installations. GasTrack is IP-67 packaged and has a five year battery lifetime. The highly accurate digital pressure and temperature sensors are sampled and recorded in non-volatile flash memory. The position of the slam shut valve is also captured during each sample period. All recorded data is periodically transmitted to secure cloud-based data servers using encrypted cellular telemetry.
In the event there is a change in the slam shut valve position or a pressure or temperature alarm condition is detected, users are immediatly notified via email and/or SMS text messages of site conditions, allowing efficient personnel deployment.

Improving System Stability and Asset Awareness
|
The Enetics family of gas monitoring products is designed to monitor:
-
Bi-directional Flow Velocity and Flow Volume
-
Static Pressure
-
Temperature
-
Humidity
-
Vibration
By monitoring the above parameters, your utility may acquire data and be quickly alerted to issues before they become full blown emergencies. Enetics gas monitoring products are reasonably priced and are intended to be deployed throughout the distribution system. You'll have your finger on the pulse of the entire system at any given time, even in remote areas where there is no SCADA, power, or communication installed.

GasTrack™ Recording Telemetry Unit
Pressure, Temperature and Slam Shut Monitoring
|
|
 |
GasTrack is your first responder in the field.
The GasTrack Recording Telemetry Unit (RTU) interfaces with the Enetics GasComm® Sensor Array and Enetics Pressure Sensors to provide utilities with the information they need to improve and maintain system stability. The GasTrack RTU is designed to provide secure and reliable wireless natural gas distribution network monitoring without the need for power drops or radio networks. Fast alarm notifications (user-defined) and accurate trend data assures full situational awareness of emerging distribution network issues.
GasTrack can also be used to monitor your slam shut valves for activation.
GasTrack utilizes fast-emerging narrowband LTE Cat M1 cellular network technology to provide secure (encrypted) and reliable data telemetry coupled with up to a five year battery lifetime. Simple to install, GasTrack eliminates the need for site maintenance and data collection visits, freeing your team to address more pressing issues.

GasComm® Control Module (GCM)
SCADA RTU ModBus 485 Interface
|
|
|
 |
The GasComm Control Module (GCM) allows GasComm sensor array data to be securely accessed by existing SCADA networks. Simple Modbus polling by Utility RTU's allows existing SCADA data pathways and security protocols to operate undisturbed. The GCM can interface the Enetics family of sensors (GasComm Sensor Array and Enetics Pressure Sensors).
The GCM can be polled by your SCADA RTU's as fast as every five seconds using Modbus 485 protocols. This allows data collection as required to conform with existing SCADA system protocols and security measures. Alarm threshold events are defined and recognized by thte Utility SCADA system. The GCM is intended to be installed in environments where external DC power is available, such as at a SCADA point.

GasPoint™ Recording Telemetry Unit
Pressure and Temperature Recording Circular Chart Upgrades / Replacement
|
 |
The GasPoint recording telemetry unit (RTU) is designed to provide a simple and reliable upgrade from natural gas circular chart pressure recorders. Internal pressure and temperature sensors with direct connections to existing site hardware, encrypted cellular telemetry and a five year battery lifetime combine to provide utilities fast alarm notifications and reliable cloud-based performance trending. GasPoint provides a simple, paperless solution to improve situational awareness of emerging distribution network issues and daily asset performance.
Operate GasPoint in parallel with existing chart recorders to provide fast alarm notification capability, or replace circular chart recorders completely, rendering chart collections and translations obsolete.

GasComm® Sensor Array
Flow velocity and volume, static pressure, temperature, humidity, vibration - single node
|
|
|
The Enetics GasComm sensor array is an advanced, patented IoT based flowmeter that also provides static pressure, temperature, humidity, and vibration monitoring in a single-node.
Class1, Division1 intrinsic safety certifications allow GasComm to be installed remotely throughtout the natural gas distribution network, acting as an affordable analytic safety monitor.
GasComm data can be captured by the Enetics GasTrack RTU, providing cellular telemetry, cloud-based storage, fast alarm notifications, and a five year battery lifetime, or by the Enetics GasComm Control Module (GCM) which interfaces to utility SCADA RTU's via simple Modbus485 polling.
GasComm can be deployed in all remote points of a network (blind spots, end-of-line, non-SCADA critical points) to monitor user-defined alarm conditions and trend day-to-day performance. GasComm is an excellent way to enhance your Distribution Integrity Management Programs (DIMP), providing an affordable and reliable means of better understanding the daily performance and readiness of your gas distribution steel or PE pipelines and improving situational awareness to minutes rather than hours or days.
