ONE Series Safety Transmitter for Crude Oil Flow Control in Pipelines
In the oil and gas industry, maintaining stable crude oil flow through pipelines is one of the most important operational requirements. Pipeline operators must ensure that crude oil moves safely and continuously from production sites to storage terminals and refineries.
Any interruption in flow can lead to production losses, equipment damage, safety risks, and expensive downtime.
Crude oil pump stations play a major role in this process. These stations maintain the required pressure and flow throughout the pipeline network. However, pump stations often face several operational challenges such as pressure fluctuations, cavitation, equipment wear, and leak risks.
To overcome these issues, operators require accurate and reliable pressure monitoring solutions.
A midstream operator in the Permian Basin recently faced similar challenges while upgrading its pump station instrumentation system. The company needed a modern solution that could improve pressure monitoring and communication without increasing installation costs or operational downtime.
This case study explains how the One Series Safety Transmitter from United Electric Controls helped solve these challenges efficiently and cost-effectively.
Challenge: Legacy Mechanical Pressure Switches Limited System Visibility
The midstream operator was operating multiple crude oil pump stations across the Permian Basin. These pump stations used traditional mechanical pressure switches for monitoring suction and discharge pressure conditions.
Although mechanical pressure switches had been used for many years, they created several operational limitations.
1. Lack of Real-Time Digital Communication
The existing switches could only provide basic switching functionality. They were unable to send continuous digital pressure signals directly to the PLC or DCS system.
As a result, operators had limited visibility into actual process conditions inside the pipeline system.
2. Difficulty in Predictive Maintenance
Without accurate pressure data, maintenance teams could not easily identify abnormal pressure trends, cavitation conditions, or early signs of equipment wear.
This increased the risk of unexpected pump failures and unplanned downtime.
3. Higher Upgrade Costs with Conventional Transmitters
The operator initially considered installing traditional pressure transmitters. However, standard transmitters usually require additional wiring and infrastructure upgrades.
Running new cables across multiple remote pump stations would significantly increase installation cost, labor requirements, and project timelines.
4. Need for a Simple Drop-In Replacement
The operator required a modern pressure monitoring solution that could:
- Work with the existing 2-wire loop infrastructure
- Integrate directly with PLC/DCS systems
- Improve monitoring accuracy
- Reduce installation complexity
- Support future maintenance planning
The solution also needed to be rugged enough for harsh oil and gas operating environments.
Solution: One Series Safety Transmitter
To address these challenges, the operator selected the One Series Safety Transmitter, specifically the 1XSWLL model from United Electric Controls.
Unlike traditional mechanical switches, the One Series Safety Transmitter combines pressure sensing, switching, and digital communication into one compact device.
The unit operates using a 2-wire loop-powered design, making it an ideal replacement for existing mechanical pressure switches.
Key Features of the One Series Safety Transmitter
1. Accurate Pressure Measurement
The One Series Safety Transmitter provides precise pressure monitoring with configurable set points.
This allows operators to continuously monitor both suction and discharge pressures in real time.
Accurate pressure data helps improve pipeline flow control and protects pumps from abnormal operating conditions.
2. Integrated Switching and Communication
One of the biggest advantages of the One Series Safety Transmitter is its ability to combine switching functionality with digital communication.
The device can send reliable loop-powered signals directly to PLC and DCS systems without requiring additional wiring.
This simplified integration significantly reduced installation costs.
3. Cost-Effective Digital Upgrade
The One Series 1XSWLL provided functionality similar to a pressure transmitter but at a lower overall project cost.
Because the unit used the same existing 2-wire loop infrastructure, the operator avoided expensive rewiring work.
This allowed the company to modernize its instrumentation system while staying within budget and maintaining project schedules.
4. Rugged and Compact Design
Oil and gas environments can be harsh due to vibration, temperature changes, dust, and outdoor exposure.
The One Series Safety Transmitter features a rugged solid-state design that supports reliable long-term operation in demanding pipeline applications.
Its compact housing also made installation easier in existing pump station layouts.
5. Easy Configuration and Installation
The programmability of the One Series Safety Transmitter allowed operators to configure pressure set points and alarms according to their process requirements.
The device was quickly integrated into the customer’s existing control architecture without major system modifications.
This minimized operational disruption during the upgrade process.
