The VAF Instruments 3504 is a Eurotherm-based process controller used in VAF viscosity-control systems for continuous monitoring and regulation of fuel-oil viscosity. A commonly documented VAF configuration is calibrated for 0–50 cSt and works with the viscosity measurement/control loop to maintain the required fuel condition before it reaches the engine.
Features
- Precise fuel-oil viscosity monitoring and control
- Typical 0–50 cSt viscosity range
- Supports 4–20 mA process input
- Advanced PID control functionality
- Automatic and manual operating modes
- Configurable alarm functions
- Relay and logic outputs
- Digital contact input
- Clear operator display and control interface
- Panel-mounted industrial construction
- Designed for integration with VAF viscosity-control systems
- Suitable for continuous marine engine fuel conditioning.
