PRODUCT INTRODUCTION

The ratio of the maximum flow rate to the minimum flow rate is generally above 20:1, and the applicable industrial pipe diameter range is wide, up to 3m. The output signal and the measured flow rate are linear, and the accuracy is high. It can measure the flow of acid, alkali salt solution, water, sewage, corrosive liquid and mud, mineral pulp, paper pulp and other fluids with conductivity ≥5μs/cm. Used in petrochemical, iron and steel metallurgy, water supply and drainage, water conservancy irrigation, water treatment, sewage treatment station (environmental sewage control, chemical sewage, electroplating sewage), paper-making (pulp), mud, medicine, food and other industrial and agricultural production companies process flow Measurement and control.

The QTLD series electromagnetic flow meter is a flow meter that performs flow testing according to Faraday's law of electromagnetic induction. The advantage of the electromagnetic flow meter is that the pressure loss is extremely small and the measurable flow range is large.


WORKING PRINCIPLE


According to the principle of Faraday electromagnetic induction, a pair of detection electrodes are installed on the tube wall perpendicular to the axis of the measuring tube and the magnetic line of force. When the conductive liquid moves along the axis of the measuring tube, the conductive liquid cuts the magnetic line of force to generate an induced electric potential. This induced electric potential consists of two The detection electrode detects that the value is proportional to the flow rate, and its value is:

  E=KBVD

  In the formula:

  E-induced electric potential;

  K-coefficient related to magnetic field distribution and axial length;

  BMagnetic induction intensity;

  VThe average flow velocity of conductive liquid;

  Delectrode distance; (measuring tube inner diameter)

The sensor uses the induced potential E as a flow signal and transmits it to the converter. After a series of digital processing by amplifying, transforming and filtering, the instantaneous flow and cumulative flow are displayed by a dot matrix liquid crystal with backlight. The converter has 4-20mA output, alarm output and frequency output, and is equipped with communication interfaces such as RS-485, and supports HART and MODBUS protocols.
