DPM-3-DLS data logging software turns a PC connected to up to 31 DPM-3 instruments into a powerful, low-cost data logging system.

Data can be displayed on the computer screen in the form of up to 64 simulated meters in 4 groups (or screens) of up to 16 meters each. The on-screen simulated meters can show the readings and alarm indications of selected actual meters, or show values other than those normally displayed by meters, such as peak value. They can also show calculated parameters, or weighted averages that combine data from multiple meters. For example, a virtual meter can display the sum of any number of meter by adding them together. Available operands are multiply, divide, add, and subtract, with parentheses to allow complex expressions. The on-screen position and appearance of individual meters is user selectable to achieve meaningful groupings.

Data can be logged from selected meters into an ASCII file, which is easily imported into MS Excel for graphing and analysis. User settable parameters include the logging time interval in seconds, the separator character (normally a comma), and header data (with or without time and date). Data files can be password protected.


Up to 31 DPM-3 meters can be connected to the PC in addressable multidrop fashion using a single RS-485 line. Each of these DPM-3 meters must be equipped with an RS-485 board. A single DPM-3 meter can be connected to a PC using an RS-232 line. That DPM-3 must be equipped with an RS-232 board.The computer must be PC compatible, operate under MS Windows 95 or higher, and have an available COM1 to COM9 serial port.

Software Installation

The DPM-3-DLS Data logging Software can be downloaded from this website at no charge. Click here to download the self-extracting install file. The free download version allows operation in the Demo Mode, which provides a good indication of the capabilities of the software. Connection to actual instruments requires a 12-digit activation code, which will be emailed by Transducer Techniques upon full payment. This code must be installed within 10 days of issue.

Common Datalogging Setup
Common Data logging Setup Screen for Simulated Meters This screen allows selection of the number of meters per group (up to 4 groups), default meter colors, and default font size for meter captions.
Datalogging Meter Setup for Groups 1 & 2
Data logging Meter Setup for Groups 1 & 2 This screen allows for setup of I.D., Caption, Type, Serial Address, and Item Number for each meter. The Type can be DPM-3, or Virtual Meter. For a DPM-3 Meter, the Item Number to be displayed can be Net or Peak. For Hardware (or actual) meters, Setpoint 1, Setpoint 2, and Decimal Point can be entered. For Virtual meters, a formula is entered.
Data logging Screen Setup for Group 1This screen provides for the spatial layout of the meters to be displayed for Group 1. Right-clicking on any meter brings up a window with allows selection of font size and color scheme for that meter. In the example shown, Meter 4 has a black and white custom color scheme.
Datalogging Setup Screen
Data logging Setup ScreenThis screen allows for creating a new data file, opening an existing data file or to display data only.The Data logging Interval are set in seconds. The Data Separator (normally a comma) can be selected. Other selectable parameters are a Header Record, and for each data record, a Time Stamp, Date Stamp, Alarm Data, and Zero Suppression.
Datalogging Start Screen
Data logging Start Screen This screen specifies the Com Port (1 or 2) and Baud Rate (300 to 19200). It also allows individual meters to be selected for data logging and to establish communication.
Datalogging Run Screen for Meter Group 1
Data logging Run Screen for Meter Group 1The display is updated for each meter in real time, including any alarm indications, while data is also written to disk. Similar screens are available for Groups 2-4.
Typical Datalogging Help Screen
Typical Data logging Help ScreenPressing on Help on the top menu bar brings comprehensive help screens, avoiding the need for a printed manual for the Data logging Software. The screen to the left is for the Demo Mode, which does not require a connection to actual meters.
