Description
Developed based on decades of field-proven experience
The AXG1A magnetic flowmeter remote transmitter is a sophisticated product with outstanding reliability and ease of operation, developed based on decades of field-proven experience.
The AXG1A employs an LCD indicator, infra-red switches, and “Easy Setup” parameters to ensure substantially improved its operationality. Its diagnostic function to detect the adhesion level on the electrodes combining with a sensor such as AXG and AXW dramatically improves maintainability at the customer.
The AXG1A also employs the “Dual Frequency Excitation Method” which is for fluid noise free for more difficult application to ensure greater stability and quicker response.
Note: The “Dual Frequency Excitation Method” is Yokogawa’s unique technology.
FEATURES
- Stable Measurement
Our own dual frequency excitation method realizes stable flow measurement even under high flow noise in the fluid with highly concentrated slurry. - Multiple Inputs and Outputs
Maximum eight inputs/outputs of current, pulse, and status signals can be selected. Mass or calorie calculation using temperature input is available. - Improved Operation and Monitoring Function
Operation authority level setting for ensuring safety, process data trend display, display backlight flashing (Squawk) function, and data store / restore function with display unit internal memory or microSD card are available. - Improved Maintainability
Diagnostic functions that contribute to preventive maintenance of the plant are installed. Diagnosis of the device (verification function) that can be executed without demounting from piping, detection of the process condition by monitoring the flow noise and electric conductivity of the fluid, electrode insulation deterioration diagnosis, electrode adhesion diagnosis, and wiring connection diagnosis are available. - Communication Protocol
HART, BRAIN
Construction
Combination with AXW Remote Sensor
Note: The accuracy above is the result of calibration test at our water flow facility before shipment. It is defined by the integrated value of the pulse output. As for the current output accuracy, add ±8 μA (±0.05% of span) to the accuracy above.
Calibration takes place at reference conditions as below.
