No. EJL- 106A Density (Consistency) Meter LQ500 Introduction The LQ500 density (consistency) meter uses microwave phase shift technology to determine concentrations of solids in the material to be measured flowing through pipes.
LQ500 2 range, which is the upper limit setting range. Resolution: Meter size 50 mm (2”) 80 mm (3”)to 300 mm (12”) Resolution 0.002%TS 0.001%TS Note 1: Above values are the results of comm uting ability in the phase measurements of the converter.

(8) Install the LQ500 in a place where enough water pressure is applied. Therefore, it is recommended that the LQ500 be installed as far away as possible from the pipe outlet opened to atmosphere.
