ZRN-MD-D vibration type density meter Online Is our latest generation of vibration density meter structure, and is equipped with a microprocessor-based electronic conversion device, the set of signal processing, calculation and diagnostic functions in one. In addition to convincing accuracy and reliability, it can be used with PC direct communication via the RS485 interface at ADView software environment, the user can directly be online node configuration, troubleshooting, and data recording. In measuring the density and temperature, but also to calculate the basic density, Brix and the percentage of concentration, the percentage of mass, volume percentage, the proportion of other parameters. There's even a user-defined quadratic equation can be used.
The liquid density meter can be installed directly on the tanks and piping, fluid viscosity measurement which may be up to 20000cP, which is superior to other similar products it is a significant feature, but it also has a strong cost performance.
ZRN-MD-D vibration type density meter Online Designed according to the principles of vibration sensor, the vibration of the tuning fork element similar to two teeth, fork body because in the root of a piezoelectric crystal and vibration, the vibration frequency is detected by another piezoelectric crystals out by phase shift and amplifier circuit , the fork is stabilized at the natural resonant frequency.
When the liquid flows through the fork, vibrating changed, causing the resonant frequency, so that by the electronic processing unit to calculate the exact value of the relationship between the density and the density of the vibration frequency as:. Ρ = K0 + K1T + K2T2
Where, ρ- liquid density
Vibration sensor output cycle T-
K0, K1, constant K2- sensor calibrated at the factory
