Description
Chuanyi Differential Pressure Flowmeter Technical Data and Selection Guide
Chuanyi Differential Pressure Flowmeter is supplied by SANTAN for industrial process control, pipeline instrumentation and maintenance replacement projects.
Product Overview
Chuanyi differential-pressure flow measurement solutions determine flow from the pressure difference generated by a primary flow element. The system normally combines an orifice, nozzle, Venturi or averaging element with a differential-pressure transmitter, manifold, impulse piping and pressure-temperature compensation where required.
Chuanyi Product-Family Information
Chuanyi lists differential-pressure flowmeters as part of its complete flow-instrument portfolio for gases, liquids and steam. The measurement system must be engineered as a complete assembly because primary-element geometry, line conditions, transmitter range and installation directly affect uncertainty and pressure loss.
Detailed Technical Parameters
| Parameter | Selection Guidance |
|---|---|
| Measurement principle | Flow derived from differential pressure across a calibrated primary element |
| Measured media | Liquids, gases or steam in single-phase service |
| Primary elements | Orifice plate, flow nozzle, Venturi, averaging tube or project-specific element |
| Transmitter | Differential-pressure transmitter range selected from calculated maximum differential pressure |
| Flow relationship | Volumetric or mass flow calculation with square-root extraction and compensation as required |
| Line data | Pipe internal diameter, schedule, roughness and straight-run layout are required |
| Process data | Minimum/normal/maximum flow, pressure, temperature, density, viscosity and composition |
| Pressure loss | Depends on the selected primary element and beta ratio |
| Connections | Flanges, pressure taps, manifold and impulse lines designed to project standard |
| Outputs | 4-20 mA/HART or digital protocol according to selected transmitter and flow computer |
Typical Industry Applications
Steam and boiler flow, natural gas and process gas, feedwater, cooling water, chemical liquids, compressed air, high-temperature lines and applications governed by established differential-pressure standards.
Information Required for Model Selection
Fluid composition and phase, flow range, line pressure and temperature, density and viscosity, pipe size/schedule/material, allowable pressure loss, primary-element preference, tap arrangement, transmitter range, manifold, impulse piping, compensation inputs, accuracy, output, approvals and required calculations.
Engineering Notes
- Confirm the complete model code and nameplate data before ordering a replacement.
- Verify process compatibility, pressure/temperature limits and installation conditions against the approved manufacturer datasheet.
- Final specifications vary by model suffix, material, connection, signal and certification option.
- SANTAN can review datasheets, project tags and replacement requirements before quotation.
