Fisher L2 and L2sj Liquid Level Controllers
Rp123000.00
Product Description
The Fisher L2 and L2sj liquid level controllers utilize a displacer-type sensor to detect liquid levels or interfaces between liquids with different specific gravities. These controllers are highly reliable, making them ideal for high-pressure liquid level applications in natural gas production, compression, and processing.
Key Features
Reliable Level Control: A two-stage proportional relay with integral action ensures precise and dependable liquid level control.
Minimal Friction and Sensitivity: O-ring friction and process pressure sensitivity are minimized, maintaining consistent performance despite pressure changes and ensuring resistance to vibrations.
Flexible Field Adjustments:
Displacer can be set for vertical or horizontal operation without additional components.
Controller action (direct or reverse) can also be changed in the field without extra parts.
Robust Sensor Assembly: Designed for ASME B16.34 CL1500 service when paired with a Polyvinylchloride (PVC) displacer.
Exhaust Management: Allows piping away of exhaust, enabling the use of natural gas as the operating medium.
Ease of Maintenance: Both the controller and sensor can be easily disassembled for inspection and maintenance of process seals.
