1. How to adjust the Chuanyi flowmeter?
Adjust it by pressing the compound button and confirmation button.
1、 Check the correct connection method of instruments on pipelines (including power lines) and the firmness of installation.
2、 Then ground the sensor part properly and ensure that the fluid in the pipeline is still when debugging the instrument zero point.
3、 After the power switch of the instrument is turned on, the instrument automatically enters the measurement state.
4、 In the measurement state of Fanjuetuan, press the "composite key+confirm key" to select the function interface of the converter and adjust the Chuanyi flowmeter.

3. What is the name of a flowmeter?
Electromagnetic flowmeter is a flowmeter that measures flow based on Faradays law of electromagnetic induction.
. The advantages of electromagnetic flowmeter are minimal pressure loss and a wide range of measurable flow rates. The ratio of high flow rate to low flow rate is generally above 20:1, suitable for a wide range of industrial pipe diameters, up to 3m after the stove is disassembled. The output signal is linear with the measured flow rate, with high accuracy. It can measure the fluid flow rate of acids, alkalis, salt solutions, water, sewage, corrosive liquids, as well as mud, slurry, pulp, etc. with conductivity ≥ 5 μ s/cm. But it cannot measure the flow of gas, steam, and purified water. When a conductor cuts magnetic field lines in a magnetic field, an induced potential is generated in the conductor, and the magnitude of the induced potential is proportional to the effective length of the conductor in the magnetic field and th

(1). In the formula, Ex - induced potential, V; B - magnetic induction intensity, TD - inner diameter of the pipeline, mv - average flow velocity of the liquid, m/s。 However, the volumetric flow rate qv is equal to the product of the fluid velocity v and the pipeline cross-sectional area (π D)/4. Substituting equation
(1) into this equation yields: Qv=(π D/4B) * Ex - - - - - - - Equation
(2). As can be seen from the above equation, when the diameter D of the pipeline is fixed and the magnetic induction intensity B remains constant, the measured volume flow rate is linearly related to the induced potential. If an electrode is inserted on each side of the pipeline, an induced potential Ex can be introduced, and the magnitude of this potential can be measured to obtain the volumetric flow rate. According to Faradays principle of electromagnetic induction, a pair of detection electrodes are installed on the tube wall perpendicular to the axis of the measuring tube and the magnetic field lines. When the conductive liquid moves along the axis of the measuring tube, it cuts the magnetic field lines and generates an induced potential. This induced potential is detected by the two detection electrodes, and its value is proportion
