Laminar LC系列流量计

The LC Series Flow Controller utilises a proportional valve coupled to a flow meter body creating a unique in-situ closed-loop flow controller system. Measurements are taken within the laminar region of the flow meter and the integral PID controller positions the valve according to the flow set points.

More details:

These robust, closed-loop devices accept a selectable analog or digital control set point from either external devices or one of Alicat’s Local Set Point Modules (LSPM). The controllers can also accept an RS-232, 0-10Vdc or 4-20mA control-input signal depending on what is preferred by the customer. Independent of the set point voltages, the controllers can be configured for single or dual output of the same or different voltages and/or different parameters such as temperature and flow. This is possible because of our laminar flow meter design that incorporates solid-state Differential, Absolute Pressure, and Temperature sensors to determine flow in an inherently linear system. The result is a fast responding linear flow meter with multiple outputs. All these parameters are simultaneously visible with our dynamic display that includes a push button operator interface. Liquid controllers are available from 50 milliliters per minute full scale to 500 milliliters per minute full scale.
