A plant-wide Chuanyi solution can combine flow, pressure, radar level, temperature, control valves, valve positioners, electric actuators, analysers and PAS300 DCS integration around one process-data architecture.
Industrial projects rarely succeed by selecting each instrument in isolation. Measurement range, materials, diagnostics, communication, valve action, control strategy, maintenance access and spare-parts policy should be coordinated from the field device to the control room. This guide maps key Chuanyi product families to practical industry solution packages.
Chuanyi Product Architecture for Integrated Projects
| Layer | Representative Chuanyi products | Project role |
|---|---|---|
| Flow measurement | MFE electromagnetic, vortex, metal-tube rotameter, DP, Coriolis, turbine, thermal mass and ultrasonic flowmeters | Liquid, gas and steam measurement across process and utility systems. |
| Pressure and temperature | PDS pressure/DP/level/remote-seal transmitters; TTS smart temperature transmitter; WR thermocouples; WZ RTDs | Core process variables, energy systems and equipment protection. |
| Level measurement | MPS7000 / MPS5000 / MPS3000 radar; MGS guided-wave radar; MB magnetic level gauge; VS tuning fork switch | Continuous level, interface and high/low-level protection. |
| Final control element | Control valves, ball valves, butterfly valves, HVP3 smart valve positioner | Modulating and isolation control with diagnostics. |
| Electric actuation | M13/14 series linear intelligent electric actuators | Valve positioning from switching or 4-20 mA control signals. |
| Process and environmental analysis | PS7000 process analysis; PS7400 CEMS; DT600; online water-quality analysers | Quality, combustion, emissions and environmental compliance measurement. |
| Control system | PAS300 distributed control system | Integrated process control, redundancy, communications and plant data. |
Solution 1: Petrochemical and Chemical Process Unit
| Process area | Recommended Chuanyi families | Engineering value |
|---|---|---|
| Feed and product lines | MFE electromagnetic, vortex, Coriolis, turbine or DP flowmeter according to fluid | Match measurement principle to conductivity, phase, pressure loss and accuracy. |
| Reactors and columns | PDS pressure/DP/remote-seal transmitter; MPS7000 radar; MGS guided-wave radar | Pressure, interface and level measurement under vapour, temperature and corrosion. |
| Control loops | Chuanyi control valve with HVP3 smart positioner | Valve diagnostics, one-key initialisation and severe-environment protection. |
| Temperature points | WR thermocouple, WZ RTD and TTS smart temperature transmitter | Sensor/transmitter package for reactors, heat exchangers and utilities. |
| Plant control | PAS300 DCS | Redundant process control and integration of field signals and diagnostics. |
The HVP3 positioner accepts 4-20 mA and digital signals. Chuanyi lists 0.5-class accuracy, 0.2-0.6 MPa air supply, low air consumption, 10-100 mm linear travel or 60-120 degree rotation, -40 to +80°C ambient rating for published configurations, IP66 protection and multiple gas/dust explosion-protection types. Its diagnostic functions and modular design are relevant to oil, chemical, metallurgy and power control loops.
Solution 2: Municipal Water and Wastewater
| Process area | Recommended Chuanyi families | Key checks |
|---|---|---|
| Raw and treated water flow | MFE electromagnetic flowmeter | Pipe-full condition, low velocity, grounding, IP rating and remote mounting. |
| Dosing and sludge | MFE or suitable positive mass-flow technology | Chemical compatibility, solids, coating and minimum stable flow. |
| Tank and wet-well level | MPS radar, HS-AW ultrasonic or hydrostatic PDS configuration | Foam, condensation, obstruction, flood risk and mounting. |
| Water quality | Online water-quality analyser / 70X3 explosion-proof water-quality analyser where applicable | Sensor cleaning, calibration, temperature compensation and area classification. |
| Control and optimisation | PAS300 DCS with pump/valve integration | Flow-paced dosing, alarm management and historian/MES connection. |
For water plants, a useful optimisation loop combines raw-water quality, inlet flow and PAC/PAM dosing rather than operating pumps from a fixed manual setpoint. This can improve chemical use and stabilise treated-water quality. See the Water & Wastewater solution page.
Solution 3: Power Generation and Steam
| Measurement / control duty | Chuanyi families | Engineering priorities |
|---|---|---|
| Boiler and steam pressure/DP | PDS pressure and differential-pressure transmitters | Static pressure, impulse piping, condensate pots, response and SIL requirement. |
| Steam and water flow | Vortex, DP or electromagnetic flowmeter according to medium | Temperature, compensation, straight runs, vibration and conductivity. |
| Coal, ash and liquid level | MPS7000 radar, MPS5000, MPS3000, RS/RAS/VS switches | Dust, steam, false echoes, high temperature and independent overfill alarms. |
| Valve automation | Control valve + HVP3, or M13/14 electric actuator | Fail action, actuator force, control signal, diagnostics and maintenance. |
| Emissions monitoring | PS7400 CEMS | Sample conditioning, analyser span, calibration and regulatory reporting. |
MPS7000 Radar Level Application Notes
Chuanyi publishes the MPS7000 family for demanding level duties in petrochemical, power, metallurgy and cement applications. Product literature highlights a dual-CPU architecture, IP66/IP67 enclosure, surge protection, remote commissioning/diagnostics, waveform display and false-echo handling. High-temperature arrangements may use an extended antenna and purge/cooling configuration, with published design temperature up to 350°C for applicable designs. Tank geometry, nozzle, antenna, dielectric constant, vapour, foam, dust and agitators must still be reviewed for each application.
