Technical details and manufacturing context for Pressure Regulation System

Definition
The Pressure Regulation System is a critical component of the Industrial Electromagnetic Flow Meter Calibrator responsible for establishing, maintaining, and adjusting the fluid pressure to specific setpoints required for accurate flow meter calibration. It ensures stable pressure conditions during testing procedures by compensating for flow variations, temperature changes, and system disturbances. The system typically consists of pressure sensors, control valves, and a feedback controller. Pressure sensors monitor the actual pressure in the calibration loop, comparing it to the target pressure setpoint. The controller processes this error signal and adjusts control valves (such as proportional or servo valves) to regulate fluid flow into or out of the system, maintaining the desired pressure. Advanced systems may use PID control algorithms for precise regulation. The system is designed for integration into the calibrator, with a compact footprint of 400×300×200 mm and a weight of 15–25 kg depending on configuration. It operates within a pressure range of 1.0–1.6 MPa, and provides pressure control accuracy of ±0.5% FS to ensure calibration repeatability. The flow rate range covers 0.1–10 m³/h, suitable for typical flow meter sizes. Response time is ≤100 ms for dynamic pressure changes. The system requires a 24 V DC supply (24 ±10%) and consumes ≤50 W. It operates in ambient temperatures of 0–50 °C and can be stored at -20–70 °C. Ingress protection is rated IP54–IP65 per IEC 60529, and the wetted parts are made of corrosion-resistant stainless steel 316L (per ASTM A240). Materials on file include stainless steel, brass, PTFE seals, and electronic components. For any specific application, verify model-specific values and standards with the legal manufacturer or supplier.
Working Principle
The system uses a closed-loop control mechanism. Pressure sensors continuously measure the actual pressure in the calibration loop. The measured value is compared to the target setpoint, and the error signal is processed by a controller. The controller adjusts control valves (proportional or servo) to modulate fluid flow into or out of the system, thereby correcting any deviation. Advanced implementations may employ PID algorithms to optimize response and stability. This ensures that the pressure remains at the desired level despite disturbances such as flow changes or temperature variations.
