What is the working principle of Micro Motion Density Meter?
WPX301 Density meter works based on the principle of component vibration. The component part is the tuning fork part immersed in the liquid to be measured. The tuning fork part induces vibration through an internal piezoelectric device fixed at the bottom end of the fork body. The oscillating frequency is detected by a secondary piezoelectric device fixed to the other end of the fork, and then the signal is amplified by the circuit on the top.
The density of the liquid is closely related to the vibration frequency when the measured liquid flows. When the density of the measured liquid changes, the vibration frequency when the liquid flows also changes. Through the following equation, the density of the measured liquid can be accurately calculated.
D = K0+K1T+K2T2
D=uncalibrated density of the measured medium (kg/m³)
T = vibration frequency (μs).
K0, K1, K2=constant

In order to ensure the density meter can measure accurately and display stability, there are necessary conditions should be met as below
● Measured medium flow rate should not be greater than 1m/s;
● Pipe diameter for installing the density meter should be greater than or equal to 159mm;
● Location of density meter should be installed as far away as possible from the pump, at least 5m suggested;
● When the flow rate is greater than 1 m/s, use the expanded diameter installation;
● When the flow rate increases by 1m, the pipe diameter of the density meter is increased by 1.5 times;
● Must be a straight pipe section ≥ 600mm before this meter;a straight pipe section ≥ 300mm behind the meter;
● Fluid is in a laminar state when flow through the fork body.
