Dataloggers in Thickness Monitoring

About Dataloggers in Thickness Monitoring (TM)

Dataloggers are data collection devices, which are used to measure and record the thickness of a component. Using the Thickness Monitoring (TM) module, you can:

  • Send data related to a TML to the datalogger.
  • Receive data from the datalogger (after you collect measurement data in the field and record it in the datalogger).
Important: If your company restricts the use of removable storage devices in USB ports, the datalogger device may not function as expected. You must request an exemption to the company policy from your IT administrator.

The following dataloggers are supported in TM:

  • GE DMS Go
  • GE DMS Go+
  • GE DMS2
  • Olympus (Panametrics) 37DL Plus Ultrasonic Thickness Gage
  • Olympus (Panametrics) 38DL Plus Ultrasonic Thickness Gage

For each datalogger, GE Digital APM provides:

To use dataloggers, you must install the latest version of the Meridium Devices Service.

If you have modified the Public\Meridium\Modules\Thickness Monitoring\Queries\TM Assets query, you must revert the query to baseline or add the following SQL code for piping Asset to the query.

Ultra-MATE software version compatibility Issue with DMS Go+ device

When you attempt to send TML data using a DMS Go+ device, the data processing starts, but never gets completed. The loading spinner continues to spin as shown in the image below.

You can also access the log file from the log folder in the service path folder to check the following error message:
Exception occurred while processing the resuestLength cannot be less than zero. Parameter name: length

Cause

The data format in DMS Go+ is changed in version 3.29. UltraMATE version older than 2.60.35 are not able to read data created with DMS Go+ version 3.29 due to the changed data format. UltraMATE version 2.60.28 or lower are able to read data created with DMS Go+ version 3.28 or lower.

Solution

GE Digital recommends customers with an existing valid license of UltraMATE software to download the UltraMATE version 2.60.35 from the https://www.gemeasurement.com/download-center. Contact GE Technical Support to get the password to unzip and install the UltraMATE software.

Incorrect readings are received

If you are a non-English customer, you may receive incorrect readings from the device.

Cause

When you receive thickness measurement data from a TM Datalogger in a system where the Windows Region format is set to any region other than English (United States), you may receive incorrect measurement values. For example, if you are using GE Digital APM in a system where the windows culture is set to Finnish (fi-FL) culture, a value of 0.75 inches may be received as 75234724750 inches.

Solution

Meridium Device Service is not running under an authorized service account

When you attempt to send TML data, following error message appears:

Error: <Directory>.dmsdr was not successfully sent to the GE DMS Go/Go+ device. Please check and make sure that all of the settings for the current device are correct. This might be due to the device having to change the file name because of limitations inherent in the device.
