Detection of Electrode Adhesion (Insulator)

If you remove the detector and check the inside, there are no deposits, and as a result there is no experience in wasting the removal work?

With ADMAG AXG, it is available to monitor the adhesion of the electrode while continuing the flow measurement without removing the detector. This contributes to the development of a maintenance plan.

Detection of Flow Noise (Air bubbles, Slurry)

Even with conventional models, we have provided stable flow measurement using our dual-frequency excitation method, our proprietary signal processing technology.
Furthermore, ADMAG AXG can display and output the strength of flow noise separately from flow signal output. As a result, while realizing stable flow rate measurement, it is possible to grasp when flow noise is generated at "when," "how long," and "how much strength", thus contributing to flow noise countermeasures.

Process Data Trend Display

Have you ever wanted to simply grasp the process values in a trend graph without using external equipment?

ADMAG AXG can display process values as trend graphs, as well as numerical information, and can “visualize” process value changes from the past to the present. This function displays one process value per screen, and it can switch up to four process values by switching the screen. There are 11 types of process values that can be displayed, and 6 types of screen update cycles. The vertical axis is scaled automatically and always displays a graph that is easy to see.

Data Logging Function

Have you ever wanted to simply record process information without using an external device?

ADMAG AXG can be equipped with a microSD card (optional) and can store process information.
This makes it possible to record process information simply if there is a device itself. Also, data is stored in text format.
Therefore, analysis using spreadsheet software is also possible by importing data into a PC via a microSD card.

This function can record up to four process information simultaneously.
Ten types of recordable process information are available.
It is available to set the sampling cycle from 7 types and the continuous recording time from 8 types.

Verification (Device Health Diagnosis) Function

How long does it take each machine to carry out an equipment inspection?

It varies according to application and process, inspection item and worker skill.
ADMAG AXG offers the following three methods to easily diagnose the soundness of equipment. It is available to choose the best diagnosis method according to the situation and the diagnosis you want to check. Anyone can check the same item automatically.

Built-in Verification Function (Our proprietary patented technology)

Built-in verification diagnoses the integrity of the transmitter and detector.
As the soundness of the converter, it diagnoses three items: “Calculation circuit”, “Device status (error history)” and “Connection status”.
We diagnose two of "magnetic circuit" and "excitation circuit" as soundness of the detector.
Then, based on the results of these five soundness diagnoses, the soundness of the entire device is diagnosed.

Standard Verification

In addition to the diagnostic content of the built-in verification function, the standard verification function can inspect the appearance of the chassis and display board, and diagnose the dot missing of the LCD.
In addition, since the diagnosis results can be output as A4 size PDF, they can be used as supplementary data for reporting and management of inspection history.
To use the standard verification function, separately purchase the "FSA130 ADMAG TI Verification Tool".

Enhanced Verification

The extended verification function can diagnose the soundness of current input / output, pulse output, transducer accuracy, and electrode insulation resistance by using external devices in addition to the standard verification diagnostic contents.
In addition, manual input of the diagnosis results not only increase the number of diagnosis items but also improve the diagnosis accuracy of the soundness. This also can output the diagnosis result as A4 size PDF. To use the extended verification function, separately purchase the "FSA130 ADMAG TI Verification Tool".

Available microSD Card

Have you ever taken the time to backup device parameters, copy parameters to replacement devices, etc.?
Also, have you ever wanted to simply record process information without using an external device?

With ADMAG AXG, you can install microSD card to the converter by selecting option.
Using the microSD card enables easy recording of process information in addition to backup / restore / duplication of parameters, which is useful for improving maintenance work efficiency and analyzing process status.

Parameter Backup / Restore / Duplication Function

ADMAG AXG can be equipped with a microSD card (optional) and can backup / restore / duplicate parameter information using the microSD card or a memory with a built-in LCD.

With these functions, for example, if there is a defect in the parameter settings, you can restore the previous settings. In addition, since the factory settings are maintained, it is possible to reset to the factory settings. Furthermore, it is possible to duplicate multiple devices with the same parameters, which contributes to the realization of rapid device replacement.

Data Logging Function

Have you ever wanted to simply record process information without using an external device?

ADMAG AXG can be equipped with a microSD card (optional) and can store process information.
This makes it possible to record process information simply if there is a device itself. Also, data is stored in text format.
Therefore, analysis using spreadsheet software is also possible by importing data into a PC via a microSD card.

This function can record up to four process information simultaneously.
Ten types of recordable process information are available.
It is available to set the sampling cycle from 7 types and the continuous recording time from 8 types.

Dual Frequency Excitation Method

By combining the signals obtained by low frequency excitation and high frequency excitation, it is our unique revolutionary excitation method that has succeeded in covering each defect and extracting only the superiority.
It combines the advantages of low frequency excitation zero points stability, high frequency excitation noise resistance and high speed response.

Both noise resistance and zero points stability

The flow noise that appears when measuring slurry fluid or low conductivity fluid has "1/f characteristics".
In other words, low frequency components tend to be noisy, while high frequency components tend to be less noisy. Therefore, high frequency excitation is effective to ensure noise resistance. However, in conventional high frequency excitation, there was a problem that "zero points become unstable".

In "Dual Frequency Excitation Method", sampling is performed in the area not affected by noise on the high frequency side, and stable zero points components are extracted with a large time constant on the low frequency side. Therefore, the synthesized signal has a very small effect of noise and stable zero points.

“0.1 seconds” fast response

In order to realize the stability of the zero points while reducing the influence of noise, the time constant is generally increased.
But that would hurt responsiveness.
The solution is "Dual Frequency Excitation Method" how to simultaneously meet the effects of noise reduction, zero points stability and response.
In “Dual Frequency Excitation Method”, high-speed response of “0.1 seconds” is possible because the change in flow rate is detected on the high frequency side.

Display and output of Flow Noise Intensity

Conventional models have removed flow noise signals using our proprietary signal processing technology "Dual Frequency Excitation Method".
On the other hand, understanding the fluid noise signal is also useful for identifying the cause of occurrence and preventing it.

With ADMAG AXG, the intensity of flow noise can be displayed and output separately from flow signal output. As a result, while realizing stable flow rate measurement, it has become possible to grasp at what intensity fluid noise is generated.

This makes it possible to monitor conditions such as air bubble / slurry contamination, lining wear, and liquid replacement (chemical injection, cleaning) that are the causes of flow noise.

Flow Noise Diagnosis Function

With "Dual Frequency Excitation Method", our proprietary signal processing technology, the flow noise signal that has been removed in the conventional model is actively taken in ADMAG AXG, and while maintaining a stable output of the flow signal, the magnitude of the generated flow noise is it can be output (It can also be assigned to 4-20 mA output).

In addition to flow noise caused by air bubbles and slurry, it also contributes to the estimation of conductivity changes due to chemical injection and liquid replacement, lining wear, and the occurrence of uneven flow.

Electrode Adhesion Detection

Preventing electrode adhesion in advance is one point of stable flow rate measurement. With ADMAG AXG, the degree of adhesion can be displayed in 4 levels.
In addition, the degree of adhesion in the detector can be grasped while installed in piping, which contributes to the reduction of inspection man-hours.

Low Conductivity Diagnosis

The maintenance of conductivity, in particular to prevent significant drops, is one point of stable flow measurement.
In ADMAG AXG, monitoring changes in conductivity and catching signs of a significant drop will contribute to early action.

Sensor Empty Check

The electromagnetic flowmeter can not perform accurate measurement if the inside of the detector is empty (non-full).
In ADMAG AXG, by constantly monitoring the condition in the piping, it contributes to the realization of continuous and stable flow measurement.

Electrode Insulation Deterioration Diagnosis

The fluid that the electromagnetic flowmeter can measure is a fluid that has conductivity.
In the case of highly corrosive fluid, it may penetrate from the gap between the electrode and the lining, etc. and degrade the insulation resistance.
If corrosion of the insulation resistance progresses, the electrode and the ground may be shorted, which may cause measurement to be impossible.
In ADMAG AXG, monitoring the insulation state of the electrode and catching the sign of short circuit contribute to the early measures.
