DTS300 Series Smart Online Differential Pressure Densimeter

The DTS300 Series Smart Online Density Transmitter (also known as an online density meter / densimeter) is designed for continuous real-time measurement of liquid density and concentration directly in industrial processes. It utilizes an advanced capacitive differential pressure sensor paired with two pressure relays inserted into the pipeline. A built-in temperature sensor is positioned between the relays to automatically compensate for process temperature changes, ensuring stable and accurate measurement. As a two-wire transmitter, it outputs a 4-20mA analog signal proportional to the measured density or concentration and supports digital communication (RS485, HART) for remote calibration and monitoring. It is widely used in process control applications across various industries.
