Description
Large diameter sewage flow meter DN150 adopts power consumption microprocessor with high integration, fast operation speed and high calculation accuracy. Frequency programmable low-frequency rectangular wave excitation improves the stability of flow measurement, low power loss; digital processing, strong anti-interference ability, reliable measurement; easy to use, simple operation, high-definition backlight and wide temperature LCD display.
Provide isolated or non isolated RS485 / RS232C digital communication interface, and support modbus, PROFIBUS-DP, Hart and other fieldbus communication modes. Using constant current source to measure the fluid resistance, the internal resistance of electrode signal can be accurately measured in the case of long line transmission. To determine whether the fluid in the sensor is empty or not, it can identify abnormal phenomena such as electrode pollution and coverage, and provide users with fault handling information such as cleaning electrode.
