This mass flow controller for liquids controls the flow rate of various liquids without relying on C.F., as it directly measures the mass flow rate using a Coriolis flow sensor.

LC-4000 Series

The full scale flow rate from 2 to 140g/min can be specified when placing an order. The liquid flow is controlled at a high accuracy of ±1%F.S. by using a Coriolis mass flow sensor and a solenoid valve.

Coriolis mass flow sensor allows flow measurement without relying on C.F.

Example of Use

Flow control of various liquid types

Coriolis mass flow controllers use Coriolis force to directly measure and control the mass of a liquid phase fluid. This liquid flow controller is ideal for controlling the flow rate of various liquid types. Since it is possible to control the flow rate of any liquid type regardless of C.F.
