The figure below illustrates the clear linear relationship between fluid density (consistency) and phase θ1 and phase θ2 (i.e., phase difference) of a wave transmitted through drinking water (0% density or consistency) and that passed through another fluid of different density (consistency) and comparing them against the wave's original phase.
Since contaminent do not easily affect the LQ series Density (Consistency) Meter, there is an excellent direct relationship between the phase difference and the concentration.
Accurate measurement is realized over a wide range from low concentration to high concentration.
Microwave phase difference measurement Attenuation ⊿E2: that results from scaling of founding causes measurement errors in the positive direction.
Because scaling, founding do not easily affected phase, measurements are guaranteed to be accurate and reliable.
No moving parts and no in-line projections guarantee high reliability and minimal maintainance requirement.
The absence of moving parts also greatly reduces costs for consumable like O-rings and bearings.
No moving parts means measurement of any fluid flowing through the system.
Installation into piping allows continuous density (consistency) measurement of any fluid flowing through the system.
Setting the measurement range and calibrating the meter are easily done via key operations while viewing the LCD display.
The LQ series has the HART protocol(*) as standard. We can check the density from far place connecting 4 to 20mADC current output line in Hand-held terminal.
