Description

DM8C/VD6

In 1967, Yokogawa developed the model VD6 vibration type liquid density analyzer in response to user requests for an online density analyzer that could be used in process automation. This was an important development in the instrumentation field, because density is a fundamental physical quantity, and its accurate measurement is important to almost all processes. The VD6 density analyzer has gone on to develop an excellent reputation as a highly stable, high sensitivity meter.

The new DM8 vibration type liquid density analyzer is a highly reliable, multi-function meter that builds on the experience gained with the VD6. It takes advantage of the latest computer technology to integrate a wide range of sensor techniques. Its converter incorporates a microprocessor that directly converts sensor frequency signals into density values for display. It is provided with a variety of functions such as one-touch calibration, self diagnosis and digital output (RS-232C).
