The SDV 652 vortex sensor extends the INLINE flow monitor series. This sensor for flow measurement has an accuracy of 2 percent and is designed for applications for which good linearity of the output signal and greater measurement accuracy are required. It is insensitive to temperature changes in the medium and is suitable for the measurement of process and cooling water. The integrated display allows checking on site. The device also has an analogue output (4 – 20 mA) and a PNP switching output. Additional functions like hysteresis, delay, and the output characteristic are programmable.
