SIGNAL PROCESSING UNIT FOR DENSITY (S.P.U.D. 800) DENSI-Trax SOFTWARE

DENSI-Trax software is a tool for use with the DENSITRAK® LIQUID DENSITY METER and provides the following functions:

  • Configure the input and output (I/O) settings
  • Modify the 4-20 mA span for density
  • Configure the two independent N/O or N/C Alarm contacts
  • Configure the calibration coefficients inside the processor
  • Monitor/record live data for density, temperature, etc
  • Use as a data logger to record Meter data to a “comma separated value” text file
  • A superior feature of this software is its ability to show historic data and trends. Data can be transferred directly into reports, spreadsheets or analysis programs. Data can be examined and archived on any Windows® compatible machine and can be printed out in various formats as required.
  • This instrument has two independent scalable outputs so it can measure live fluid density and temperature simultaneously.
  • Communication options include USB, RS232, and RS485 (2- WIRE) protocols.

PRINCIPLE OF OPERATION

PrinncipleOfOperation

The DENSITRAK® D625 Liquid Density Meter utilizes the oscillating U-tube as a technique to establish the density of liquids and gases based on an electronic measurement of the frequency of oscillation, from which the density value is calculated. A change in the vibrating mass, (as a result of change in the fluid density) shifts the resonant frequency. The meter produces a square wave frequency output signal that can be processed by a microprocessor based signal converter (SPUD) or commercially available flow computer (Omni Flow Computer for example). The microprocessor utilizes built in algorithms to compute density based on fluid composition, temperature, and pressure. Each densitometer has a unique set of Calibration Coefficients which are used by the micro-processor in calculating the live fluid density.
These coefficients are determined by careful calibration in the Analytical Flow Technologies laboratory for each meter individually.

We offer a variety of DENSITRAK® meter models and our engineers review each Sales
Application to determine the DENSITRAK® D625 model that best suits your specific
application.
