General Specificaition

The LQ500 Density (Consistency) Meter uses microwave phase shift technology to determine concentrations of solids in the material to be measured flowing through pipes. It can perform a stable and realtime density (consistency) measurement because this technology is not affected by flow velocity along with fluid color, and also is not easily affected by contaminants and low process pressure rate. As the LQ500 has no moving parts, it is reliable and virtually maintenance free.

Since the output of the LQ500 is theoretically linear, it can be applied to a wide range of density (consistency) measurement.

The AF900 Hand-held terminal (HART*1Communicator) can be used for remote control.
