Type 8718/8719 LFC, Liquid Flow Controller、Type 8708/8709 LFM, Liquid Flow Meter Quickstart
■The operating instructions describe the entire life cycle of the device. Keep these instructions in a location which is easily accessible to every user and make these instructions available to every new owner of the device.
●General description
■The LFC/LFM Types 8718, 8719/8708, 8709 are devices for controlling or measuring the flow-rate of liquids in process technology.
■The devices are specified for the control and measurement of low flow-rates.
●LFC, Liquid Flow Controller
■The actual flow-rate value supplied by the integrated sensor is compared in the digital control electronics with the set-point flow-rate value specified, via a standard signal or field bus. The actual flow-rate value is also available as an output, via a standard signal or field bus.
■If there is a control deviation, the actuating variable output to the proportional valve is modified via a control algorithm. As a result, the actual flow-rate is adjusted to the set-point value and the flow-rate can be held on a fixed value or follow a predefined profile sequence, irrespective of pressure changes or other disturbances in the system.
■A low-friction proportional valve with a high response sensitivity is used as an actuating element.
●LFM, Liquid Flow Meter
■The actual flow-rate value supplied by the integrated sensor is available as an output, via a standard signal or field bus.
