Interface Detection in Differentiated Liquid Pipe Flow with Clamp-on Ultrasonic Meter

Interface Detection in Differentiated Liquid Pipe Flow

Interface detection in differentiated liquid pipe flow refers to identifying and monitoring the boundary between two immiscible fluids (liquids that do not mix) flowing through a pipe in process control applications. In industries such as oil and gas, petrochemicals, and wastewater treatment, it is common to have a line transporting two or more immiscible liquids, often referred to as a multiphase flow. Efficient and accurate interface detection is crucial for optimizing separation processes, minimizing product contamination, and preventing damage to equipment.

Ultrasonic sensors transmit high-frequency sound waves through the fluid and measure the time it takes for the waves to reflect the interface. By analyzing the received signals, the sensors can determine the position of the interface within the pipe.

In process control, interface detection is often combined with other control strategies, such as flow rate control or temperature control, to ensure the efficient and safe operation of the process. Accurate interface detection allows for better process optimization, reduces the risk of equipment damage due to improper fluid handling, and improves overall product quality.

The Siemens SITRANS FS230 clamp-on ultrasonic interface detector is an exceptional option for applications that necessitate the detection of differentiated liquid pipe flow. It achieves this by computing the sonic velocity and pressure while adjusting for temperature variations. This direct measurement approach for interface detection leads to significant savings in equipment utilization and slop oil treatment.

The FS230 interface detector can provide oil companies with highly accurate and dependable flow and interface information for a broad range of applications, such as:
  • Detecting gasoline interfaces
  • Identifying multi-product interfaces
  • Determining product types
  • Managing automatic batching control
  • Detecting entrained water and gas presence in all products

Level Phase Split Detection and Measurement

Phase Level Detection
Phase level detection.
Need a system for continuous interface measurement? This system will monitor the emission phase and detect when phase A/B occurs, avoiding any flow of the emulsion into the incorrect area. When phases are separated, the system allows for tight control, which increases efficiency of separation of liquids A&B.

This system provides the ability to remotely view a process that may not normally be watched. Multiple viewing stations may be linked to the system output so various departments may monitor a process. Customers may purchase video monitors, amplifiers or screen splitters to enhance the system.

  • Ethernet systems allow the additional functionality of being able to remotely view through a Gigabit network system. Users can have access to live system images from their office networked computer. 
  • Software is available for customers that require additional functionality over simple viewing of a live image. Liquid level, color of different phases, and visual verification. 
System verifies the color of fluid in phase split and sends an output signal locating specific points of the interface. All measurements can be recorded and archived for a historical record. 

Monitor phase split in batch mode on organic droplets for increased product recovery. As the droplets appear the system warns of organic phase and the upcoming emulsion. The amount of early droplets and their retraction time will indicate the completeness of the separation. Once the split is identified and stopped, the operator has a visual verification from the video monitor. The color can then be analyzed to ensure there is no inversion.
