The LEVIFLOW® LFS inline sensor is designed for non-invasive high precision flow measurements of high purity fluids. The wet material is made from PFA and resistant against harshest chemicals. The converter with a digital signal processor (DSP) processes sensor signals. Various signals (analog output, digital input and digital output) are provided and can be configured with a PC software. A two wire RS485 bus allows arrays of multiple flow-meters. In addition, the sensor value is shown on a 4-digit display.
