DM8 Vibration Type Liquid Density Meter Bulletin 12T03A01-01E www.yokogawa.co.jp

Density is one of the fundamental physical quantities required when the property or composition of a liquid sample is being determined in industrial processes. Operation of plants which previously had to depend on human perception for density measurement due to a lack of appropriate online density meters, can be automated with the advent of YOKOGAWA's Model VD6 Vibration Type Density Meter in 1967. Developed in response to user requirements, the Model VD6 put an emphasis on saving labor, resources, energy and better and more stable quality. As part of its policy of continuing development, YOKOGAWA...

Preamplifier Density signal Temperature signal Temperature measuring element Vibrator Sample Piezo-electric element Pick-up electrode Principle of the Tuning Fork The natural frequency of a tuning fork is determined by its shape and material. If the tuning fork is hollowed out and fi lled with a liquid, the vibrating frequency is determined by the liquid's density. This is the operating principle of the Model DM8 vibration type liquid density meter. High Sensitivity and Stability Stable measurement can be performed in spite of high detecting sensitivity. The density meter is not affected by viscosity...
