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 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.

The Trend Towards Wireless Remote Monitoring Of Wellhead Tubing, Line and Casing Pressures

 

Oil and gas operators rely on the latest technology to monitor tubing and casing pressure for optimized well production.  High and low-level alarms typically are used to provide alerts on untypical well behavior in avoiding overpressure events. Tracking operating parameters over time also helps determine the long-term well performance.

Traditionally, dial gauges were incorporated into wellhead monitoring schemes.  While reliable and inexpensive, these local displays required manual intervention to record readings that were expensive when considering the cost of the truck, tools, and operator.

Next on the scene were wired monitoring and control systems that required running cable between the wellhead and a remote terminal unit (RTU).  While reliable and automatic, wired systems require trenching and cabling.  Wiring costs can range from $10 to $20 a foot, when calculating all costs, depending on the application.  As a wellhead is typically not closely located to the RTU, a run can be a half mile or more.

Over the past decade, wireless sensor networks have gained popularity in the oil and gas field, especially for tubing and casing pressure monitoring.  With no wiring or trenching requirements, installation costs are far less expensive than wired systems.  Besides, wireless remote monitoring systems can be programmed to provide alarms to prevent spills and avoid equipment failure and damage.  In many instances, mesh networking is used to gather tubing and casing pressure data from several wells.  Also, wireless systems offer a unique benefit during workovers as wireless sensors can be easily removed and reinstalled without having to equip them with new seals and conduit.

As wireless remote monitoring systems replace manual gauges and wired systems for monitoring different wellhead tubing, casing, and line pressures, SignalFire Wireless Telemetry has developed the Pressure Scout that integrates a wireless node, pressure sensor, and intrinsically safe internal battery into one package. By eliminating the need to specify and purchase a pressure sensor and wireless node separately, the Pressure Scout serves as a low-cost alternative to a conduit-wired or other wireless pressure monitoring solutions.

When used to monitor tubing, line, and casing pressures, the Pressure Scout reads pressure status according to a configured interval (every minute, every 5 minutes, etc.).  It then reports results by providing a robust, long-range transmission to a SignalFire Gateway where the pressure data becomes available via a Modbus RTU or TCP interface. Using this data, operators can view and analyze current and long-term wellhead performance.  Configurable for alarm reporting, the Pressure Scout provides more rapid notifications when the pressure sensor detects a reading outside of a set low or high threshold. The ability for the Pressure Scout to monitor pressure continuously and check in more rapidly to detect a violated threshold is critical for rapid alarming.
