  • Overview
  • Features
  • Use environment

ZKLDB series electromagnetic flow meter is based on the principle of Faraday's law of electromagnetic induction to measure the flow rate of conductive liquid, volume flow of the best products, with good price/performance ratio and high accuracy and stability, product range ratio is large, suitable for a variety of conductive liquid measurement, for strong corrosion, multi-impurities, viscous and other complex media can be measured , has a wide range of applicability.


The magnetic field of the sensor is uniform, the signal is strong, and the measurement stability is high.


Extra wide range ratio (range: 0.1m/s15m/s);


There is no blocking of flow components in the measuring tube, no pressure loss;


Three-electrode design, good grounding, no grounding ring;


Sensor special treatment, anti-jamming ability is super, almost not affected by the field high voltage, frequency conversion;


The lining material is thickened, the electrode arc surface is designed, and the sealising is excellent.


Not affected by changes in fluid density, viscosity, temperature, pressure and electrical rate;


The maximum working pressure can be customized with a maximum of 40MPa (limited caliber);


SMD device and surface installation (SMT) technology, high circuit reliability;


With conductivity measurement function, it can determine whether the sensor is empty tube, with self-test and self-diagnosis function;


High-definition backlight LCD display, full Chinese character menu operation, easy to use, simple operation, easy to learn to understand;


The converter uses programmable frequency low-frequency rectangular wave excitation to improve the stability of flow measurement and low power loss


The converter uses 16-bit embedded microprocessor, full digital processing, fast operation, strong anti-jamming ability, high accuracy;


With RS485, RS232, Hart and Modbus, Profibus-DP and other digital communication signal output;


Converters and sensors can be split, one-piece two ways, easy for users to choose according to different field.
