DFV Series Electronic Register & Level Gauge Monitor

 

Liquip have uniquely developed the DFV series which has become the most technically advanced Register and Level gauging unit available on the market.

Available as a standalone Register, Level gauge CPU or combined unit, the DFV combines long service life with simple operation and reliability.

The DFV is a lightweight unit and is approved for use in Zone 1 hazardous areas (IECEx, ATEX & UKEX) truck mounted or fixed site product transfer applications.

The DFV has various metrological approvals for use in a variety of geographical locations including but not limited to: Australia, USA, Europe, New Zealand.

The DFV is available in a wide variety of configurations. Please review model variations under the "Ordering Information" tab below.

Upgrade Procedure

A valid password is required to be entered into the DFV in order to load new firmware. The password is provided by Liquip and is based on the DFV PCB Serial Number and Bootloader Version loaded. The password is valid only for 7 days from the date of issue.

Liquip can provide the firmware attached within an email. The file must be removed from the email and copied to a formatted (FAT32) microSD card. The file provided by Liquip should have a ‘.bin’ extension, for example 02_02_00.bin.

Note in the case of DFV103, the right most character ‘D’ (eg. 02_02_00D) is always dropped from the filename stored on the microSD card (eg. 02_02_00). The ‘D’ however will appear on the LCD after loading, removing confusion as to whether DFV103 or DFV101 code was loaded.

In the case of the DFV100/DFV101/DFV102, it is recommended that a Setup Report is printed prior to loading new firmware to avoid the possible loss of Calibration data. Similarly, Diprecall may be used to save Diptronic information prior to loading new DFV103 or DFV101 firmware.

The DFV1XX firmware installation process is as follows:

  1. Provide Liquip PCB S/N, unit S/N and Bootloader version.
  2. Liquip will provide the password and firmware to allow installation of firmware.
  3. If firmware is sent by email, copy (*.BIN) firmware file to a FAT32 formatted microSD card.
  4. Power off the DFV100.
  5. Remove the sealing plug from the CAL switch.
  6. Open the front cover of the DFV100 and remove the metal cover off the MEMORY CARD connector.
  7. Insert the card into the connector, its locking notch must be down facing left, push it gently until it “clicks”. 
  8. Power on the DFV100.
  9. As soon as the message “LIQUIP DFV100” is shown on the display press CAL switch using long thin object (pen, small screwdriver, etc.), Do it within 5 seconds of hearing the audible beep at power up, otherwise the unit will start-up with the previous firmware.
  10. For Bootloader version 1.0, 1.1 or 1.2 - Now the DFV100 will load the new firmware,
  11. For Bootloader version 2.0 - Enter the 4-digit password provided to you by Liquip. There is a 10 sec timeout which quits the password entry if no key is pressed. If the password is correct, the DFV100 will load the new firmware.
  12. For Bootloader version 2.1 or higher- Enter the 9-digit password provided to you by Liquip. There is a 10 sec timeout which quits the password entry if no key is pressed. If the password is correct, the DFV100 will load the new firmware. The password is valid for limited time only (7 days).
  13. Depending on size of the firmware the whole process takes approx. 2-3 min to complete. Once finished, the unit will automatically re-boot with new application.
  14. Remove the card from the connector by pressing it gently down until it “clicks” then pull it up.
  15. Install the MEMORY CARD cover, close the lid of the DFV100 and install CAL grub screw. Perform Metrological sealing and Calibration procedures. 
DipRecall

DipRecall is a software tool which operates on a Windows OS and allows a PC or laptop to communicate with a DFV103/DFV101 over RS232. 

Its purpose is for downloading or uploading level gauge calibration data and settings, which is not only useful for keeping records of each level gauge installation, but also recovering in the event that data is lost. Because metrological data may be modified using DipRecall without breaking the calibration seal, the application requires a password to be entered at the start-up of the program.

If the PC has no available RS232 port the operator may use an USB to RS232 converter.

Please download the Diprecall files below to assist you with loading setting during installation.

DIPRECALL V3.04 - For use with DFV’s with software prior to version 03.02.03, and older DIP200-CPU’s.

DIPRECALL V3.06 - For use with DFV’s with software version 03.02.04 and later.
