What makes the MPX-F different from other level transmitters?

The MPX-F features flexible 316L stainless steel tubing with a braided stem, allowing for easy installation in tall tanks without heavy equipment. Its Modbus RTU output ensures seamless integration into existing systems, while its corrosion-resistant design ensures durability in harsh environments.

Unlike rigid level transmitters, the MPX-F’s flexible tubing can be coiled for shipping and easily uncoiled for installation, reducing the need for cranes or large lifting equipment. This significantly lowers installation costs and effort.

The MPX-F is ideal for chemical processing, water treatment, oil and gas, and food and beverage industries. It provides accurate tank level monitoring and remote access, making it suitable for a wide range of industrial applications.

Yes, the MPX-F supports remote monitoring by providing real-time data when connected to SETTLER and Explorer. This feature is especially useful for large-scale industrial applications that require continuous oversight of tank levels.

Yes, the MPX-F is constructed with corrosion-resistant 316L stainless steel tubing, ensuring long-lasting performance even in challenging environments such as chemical processing plants and wastewater treatment facilities.

Increase the sensitivity settings on your sensor.

Here are the steps to get the sensor communication back as sensor #1 using the APG Modbus software and the RST-6001 (USB to RS485 converter). 

It’s essentially the same process below to establish communication. 

 

Establishing Communication:

  1. On the APG Modbus software, go to Configure>Communication.
  2. Make sure the USB box is checked; the Sensor Type is MPX-1/4 RS485 and the Sensor# ID is showing 1.
  3. Click Save Configuration and then click Save.
  4. Click on the Green “Start Communication” Button.

After communication has been established, use the second procedure to change the sensor address. 

 

Changing the Sensor Address:

  1. Change Register 400 from 1 to the desired address number.
  2. Click Send. At this point, you will see a Comm Bad. That’s ok, go to Step 3.
  3. Click again on Configure>Communication.
  4. Change the Sensor ID from 1 to the new address number.
  5. Click Save Configuration and then click Save.
  6. Click on the Green “Start Communication” Button.

Your MPX probe should be communicating to the software with its new address.
