A Remote-Type or Split-Type Electromagnetic Flow Meter is a variation of the electromagnetic flow meter where the sensor (flow tube) and transmitter (converter) are separate units connected by a cable. This design allows the transmitter to be installed at a distance from the sensor, providing flexibility in challenging installation environments.
Separate Sensor and Transmitter:
The sensor is installed directly on the pipeline to measure the flow of conductive liquids.
The transmitter is mounted remotely, often in a control room or a safer, more accessible location.
Cable Connection:
The sensor and transmitter are connected by a shielded cable, which transmits the flow signal from the sensor to the transmitter for processing and display.
Flexible Installation:
Suitable for applications where the transmitter cannot be installed near the sensor due to environmental constraints (e.g., high temperature, hazardous areas, or limited space).
High-Temperature Environments:
The transmitter can be installed away from high-temperature fluids, protecting it from heat damage.
Hazardous Areas:
In explosive or corrosive environments, the transmitter can be placed in a safe zone, ensuring operator safety and compliance with safety standards.
Space-Constrained Locations:
Ideal for installations where space around the pipeline is limited, allowing the transmitter to be mounted in a more convenient location.
Remote Monitoring:
The transmitter can be installed in a control room for easy access to flow data and system integration.
Environmental Adaptability: Protects the transmitter from harsh conditions such as high temperature, humidity, or corrosive atmospheres.
Ease of Maintenance: The transmitter is easily accessible for calibration, troubleshooting, and maintenance.
Safety: Reduces risks in hazardous areas by keeping the transmitter in a safe location.
Installation Flexibility: Allows installation in complex or constrained environments where inline or compact meters are not feasible.
Higher Cost: Requires additional components such as cables and mounting hardware, increasing the overall cost.
Complex Installation: Proper cable routing and signal integrity must be ensured to avoid signal loss or interference.
Signal Attenuation: Long cable runs may lead to signal degradation, affecting measurement accuracy.
Fluid Properties:
Ensure the sensor materials (liner and electrodes) are compatible with the fluid's chemical composition, temperature, and abrasiveness.
Installation Environment:
Evaluate the temperature, humidity, and safety requirements to determine the optimal location for the transmitter.
Cable Length:
Choose the appropriate cable length based on the distance between the sensor and transmitter, ensuring signal stability.
Accuracy Requirements:
Select a meter with the necessary accuracy and signal processing capabilities for your application.
Sensor Placement:
Install the sensor in a straight section of the pipeline, ensuring sufficient upstream and downstream straight runs for accurate measurements.
Transmitter Placement:
Mount the transmitter in a dry, vibration-free, and easily accessible location.
Cable Routing:
Use shielded cables and avoid running them near sources of electromagnetic interference (e.g., motors, power lines).
Chemical Industry: Measuring corrosive or high-temperature fluids while keeping the transmitter in a safe area.
Power Plants: Monitoring cooling water or steam flow with the transmitter installed in a control room.
Water and Wastewater Treatment: Measuring sewage or sludge flow in challenging environments.
Oil and Gas: Monitoring flow in hazardous or remote locations.
The Remote-Type / Split-Type Electromagnetic Flow Meter is a versatile solution for applications where the transmitter cannot be installed near the sensor due to environmental, safety, or space constraints. While it may involve higher costs and more complex installation, its flexibility and adaptability make it an excellent choice for demanding industrial environments.
