The DM-Series Inline Density Meters are designed for continuous monitoring and process control of liquid concentration/density and temperature of solutions across a wide range of applications. Available in three different mounting configurations, the DM- Series density meters can be integrated directly into a variety of tanks and inline systems. Temperature compensated values can be measured and displayed in Density, Specific Gravity, Brix, Plato, Baume, API, Concentration, Solid %, and other measurements of density. Designed for process control, measured data outputs through a 4-20 mA signal. Digital communication for remote calibration and monitoring is also available.
Each unit consists of a capacitive-type differential pressure transmitter tied to a pair of pressure repeaters immersed in the solution. Temperature compensation is performed by a temperature sensor located between the two pressure repeaters. Small variations in the process temperature are quickly and accurately calculated through dedicated software.
