Product Details
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).
The DM8 is a vibration type liquid density analyzer and its
converter incorporates a microprocessor to directly convert
frequency signals from the sensor into density values and display
them and is provided with a variety of functions such as one-touch
calibration, self diagnosis, digital output.
The DM8 liquid density analyzer measures liquid density of general process liquids with high sensitivity and excellent stability. It has a measuring density range of 0 to 2.0 g/cm3, and unaffected by flow rate and viscosity. Besides general-purpose sensor, sanitary and explosionproof sensor are also available.
Features
- High sensitivity and stability.
- One touch calibration with a standard calibrating solution.
- Free setting of measuring range in the field.
- Failure alarm display and output.
- Outdoor installation of converter.
