JDK300 Electromagnetic flowmeterDetailed product description：

Detailed information

The JDK300 electromagnetic flow converter and sensor can be assembled as a single unit or separately installed as separate units, used for measuring the volumetric flow rate of liquids with conductivity greater than 5 μ s/cm.
The converter provides stable pulsating excitation current to the excitation coil of the sensor. The sensor generates a signal that reflects the flow rate. After amplification, rectification, and anti-interference circuits, it outputs a DC current signal that is linearly related to the flow rate. When paired with a downstream instrument, it achieves instantaneous display, recording, integration, and adjustment of the flow rate.
Its main performance characteristics are as follows.

——Adopting low-frequency rectangular binary wave excitation, it has strong anti-interference performance.
——The structure is simple, solid, and highly stable.
——The instrument also has bidirectional flow measurement function.
——Low power consumption is independent of sensor aperture.
——The converter has strong interchangeability, and there is no need to re calibrate the actual flow when changing the flow. The method is simple.
——Converter additional function board with calibration, pulse and frequency output to meet various user needs.
