Oil & Gas

SignalFire Telemetry products connect you with crucial product and hardware data at any of your oil and gas operation sites—whether it’s a pump, pipeline, or storage tank.

Water & Wastewater

SignalFire Telemetry devices install anywhere water asset monitoring is needed, whether it’s for collection purposes, treatment, or delivery.

General Industrial

SignalFire Telemetry devices can monitor key assets and can do it affordably, without any renovation or high-priced engineering costs. They install easily with no required cable or additional power. The data is available on your phone or computer and the cloud service can even output to your corporate system to integrate with the rest of your data and keep your operation running.

Agriculture

SignalFire Telemetry devices can monitor and manage water supplies and additives throughout the property, helping you avoid catastrophic shortages and keep your irrigation plan on track.

Tanks & Terminals

Avoid costly product loss in bulk storage tanks, terminals, and transportation movements. Whether calling for tank levels, gauge pressure, or even movement pumps or pipelines, SignalFire products can fill any monitoring gap throughout a facility.

Environmental

Environmental fines for businesses are be frustrating and can bring business to a standstill until they’re worked out. No business wants to hurt the environment, and in competitive markets stopping production affects the bottom line and staff. But there are effective and affordable solutions with SignalFire Telemetry devices.

Refining & Petrochemical

Expand visibility and control of your refinery or petrochemical processing facility without expensive renovations or redesigns. And do it with your current gauges and hardware. SignalFire telemetry devices are designed to work in harsh chemical environments and meet the strictest safety and security standards

Utilities

No matter the size of your service map, monitoring remote assets ensures efficiency and keeps your operation in compliance. That’s how SignalFire devices can really help, offering the most affordable and effective monitoring solution that will monitor liquid, gas, electricity, and other assets.

Moving from a Wired to a Wireless Remote Monitoring System

 

Remote monitoring networks provide industries with the capability to automatically track and control various assets to improve operations while reducing costs. Wired remote sensing systems are the norm, especially in the oil and gas industry. In these configurations, sensors monitoring various assets are equipped with outputs that require hundreds of feet of wire to connect to a PLC. Analog 4-20mA current loop and Modbus interfaces are examples of communication protocols that can cope with long cable runs.

However, while offering advantages over taking manual readings from sensors or gauges, wired systems can pose limitations depending on the application regarding installation costs, sensor flexibility, and environmental influences. For example, if a remote monitoring application requires multiple sensors to monitor various parameters, a wired system requires each sensor be wired back to the controller using an interface port. For large systems, a wired system requires a large interface panel with many different interfaces.

A wireless system, on the other hand, will often have a digital communications interface (Modbus RS485), allowing for many sensors to be wirelessly “connected” to the controller through a single port. While beneficial when configuring a new controller, changing from a wired interface (with lots of individual input ports) to a gateway-based wireless system with a digital interface requires pre-planning. In lieu of making a complete changeover to a wired system, SignalFire supplies modules that can convert digital information into individual analog channels, simulating the existing analog interface. Although this is the easiest solution for a quick changeover and does not require any software changes, it does not utilize the vast increase in data and diagnostic benefits that come with changing the complete communications architecture to a wireless sensor control system.

Here are some factors to consider when evaluating a move to a wireless remote monitoring and control system instead of upgrading an existing wired system.

WIRED SYSTEM WIRELESS SYSTEM
Price What is the area over which the wired system will operate? Costs related to running conduit over large areas, especially if requiring trenching, can make a wired system too cost prohibitive. With no conduit or trenching requirements, a wireless system can be installed at the cost of a wired system with 50 feet of installed conduit – less if conduit needs to be buried.
Maintenance When removing sensors for periodic maintenance, wires integrating to units can be damaged. Improper wire labeling can result in incorrect sensor replacement. In a wireless system, nodes integrate to sensors that send data directly to a gateway. When removing sensors for maintenance, the wireless node easily detaches and re-attaches without interference by wires.
Environmental Underground conduit is often ruined by equipment when digging a trench for another underground conduit run. The cost to replace conduit and cable systems can be huge. In addition, lightning strikes on a sensor will propagate along all wires, often destroying equipment attached to the system. With no underground wires, nothing must be dug when going wireless. Once installed, lighting strikes to a sensor may damage the single unit, but not interfere with the complete system.
Topography Certain locations make it impractical to run wires, such as across a highway or river. A wireless node can be easily installed on the other side of a highway or river. Self-configuring, wireless nodes automatically connect to the network.

When moving from a wired solution to a wireless one, consider all the aspects of the job. Is there a problem with what you have now? If so, are you willing to change the interface at the controller understanding that this change will allow you to take in much more data and diagnostic information than you had before? Is it more cost effective when considering the absence of cable, trenching and interface requirements? Deciding when to “pull the trigger” is the hardest part. SignalFire has found its customers benefit in the long term with a wireless system.
