The world of process automation is constantly evolving, with industries seeking more efficient and reliable ways to regulate flow, pressure, and temperature. Traditional setups rely on multiple separate components, each requiring individual installation, calibration, and maintenance.
FOCUS-1 changes this dynamic by integrating measurement, control, and computing power into a single intelligent device. But what exactly is FOCUS-1, and why is it a game-changer in process automation? This blog explains.
What is FOCUS-1?
FOCUS-1 is a Smart Meter Valve, an all-in-one device that integrates several key functions of a conventional control loop into a compact, easy-to-install solution. It was developed through a partnership between SAMSON et KROHNE, two leading manufacturers in industrial automation, combining their expertise in valve technology, measurement solutions, and smart control systems.
Unlike traditional setups that rely on separate flow meters, control valves, pressure and temperature sensors, and external PID controllers, FOCUS-1 consolidates these functions into a single unit. This integration eliminates the need for excessive wiring, flanges, and external controllers, reducing complexity and enhancing efficiency.
The core components of FOCUS-1
1. Valve technology:
- At its core, FOCUS-1 is built on the SAMSON 3241 control valve, a robust and reliable industrial valve that has been used in process industries for decades.
- The valve body features an integrated actuator and positioner, ensuring precise control over flow, pressure, and temperature.
2. Measurement technology
- The device incorporates KROHNE’s Optisonic 3400 ultrasonic flow meter, allowing accurate and reliable flow measurement.
- Built-in pressure and temperature sensors provide real-time monitoring, eliminating the need for additional external sensors.
3. Computing power and control
- The integrated smart computer connects all components, enabling real-time control and automation.
- Internal PID control eliminates the need for external controllers, simplifying the control loop.
- The smart system allows predictive maintenance, detecting wear and tear before failures occur.
How does FOCUS-1 work?
Traditional process control systems operate by measuring flow, pressure, or temperature separately and sending data to a PID controller at the control level. The controller then calculates adjustments and communicates back to a control valve or pump to regulate the process.
With FOCUS-1, this control process is streamlined and moved to the field level. The integrated computer continuously monitors and adjusts flow, pressure, and temperature, removing the need for external PID controllers. Instead of relying on multiple separate devices to communicate with one another, FOCUS-1 performs all these functions internally, responding in real time and optimizing control loops faster and more efficiently.
Key advantages of FOCUS-1
1. Simplifies system architecture
- Eliminates the need for multiple components and reduces system complexity.
- Reduces installation time, programming effort, and maintenance requirements.
2. Improves accuracy and efficiency
- Integrated sensors provide real-time data, ensuring faster response times and precise control.
- Direct control on flow, pressure, and temperature results in better process stability.
3. Enables predictive maintenance
- The internal computing system continuously monitors process conditions.
- Detects early signs of wear, leaks, or inefficiencies, reducing downtime.
4. Enhances cost savings
- Fewer components mean lower procurement, installation, and maintenance costs.
- Less cabling, flanges, and external controllers contribute to a 33% reduction in installation costs.
5. Supports sustainability goals
- Reduces energy consumption by optimizing process control.
- Minimizes material waste and unnecessary component usage.
