Supply of pulp flow meter

Supply of pulp flow meterThe measurement principle is based on Faraday's law of electromagnetic induction. The measuring tube of the flowmeter is a non-magnetic alloy short tube lined with insulating material. Two electrodes are fixed on the measuring tube by passing through the tube wall along the diameter direction. The electrode tip is basically flush with the inner surface of the lining. When the excitation coil is excited by bidirectional square wave pulses, a working magnetic field with a magnetic flux density of B will be generated in the direction perpendicular to the axis of the measuring tube. At this point, if a fluid with a certain conductivity flows through the measuring tube, an electromotive force E will be induced by cutting the magnetic field lines. The electromotive force E is proportional to the magnetic flux density B, which is the product of the inner diameter d of the measuring tube and the average flow velocity v. The electromotive force E (flow signal) is detected by the electrode and sent to the converter through a cable. After amplifying and processing the flow signal, the converter can display the fluid flow rate and output signals such as pulses and analog currents for flow control and regulation. In the equation E=KBdv, E represents the signal voltage (v) between the electrodesPulp flowmeterB - Magnetic flux density (T) d - Measuring tube inner diameter (m) v - Average flow velocity (m/s) In the equation, K and d are constants. Since the excitation current is constant, B is also constant. Therefore, from E=KBdv, it can be seen that the volume flow rate Q is proportional to the signal voltage E, that is, the signal voltage E induced by the flow velocity is linearly related to the volume Q. Therefore, as long as E is measured, the flow rate Q can be determined, which isPulp flowmeterThe basic working principle. According to E=KBdv, parameters such as temperature, density, pressure, conductivity, and liquid-solid composition ratio of the measured fluid medium will not affect the measurement results.

Pulp flow meterAs for the flow state, as long as it conforms to axisymmetric flow (such as laminar or turbulent flow), it will not affect the measurement results. Therefore, it is said thatPulp flowmeterIt is a true volumetric flowmeter. For manufacturers and users, the volumetric flow rate of any other conductive fluid medium can be measured without any correction as long as it is calibrated with ordinary water. This isPulp flowmeterOne outstanding advantage of this is that it is not found in any other flow meter. There are no active or obstructed components inside the measuring tube, so there is almost no pressure loss and it has * reliability.

Pulp flowmeter How to choose the right type
The selection of instruments is a very important task in instrument applications. Relevant data shows that 2/3 of instrument failures in practical applications are caused by incorrect selection or installation of instruments. Please pay special attention.
Pulp flowmeter Flow direction adjustment

The flow meter and flow direction regulations are described in Section 2.6.5. For separated flow meters, although installing sensors can ensure that the flow direction arrow is consistent with the actual positive direction on site. Due to issues with user wiring, the following situations may occur:

• Equipped with a unidirectional output converter, the output displays zero or negative values when there is forward flow (such as 0mA for 0-10mA or 4mA for 4-20mA).

• A converter with bidirectional display, which outputs negative display when there is positive flow. At this point, simply disconnect the power supply and adjust the positions of the two excitation lines (EXT+and EXT -) on one side to ensure that the output direction, actual forward flow direction, and arrow direction remain consistent.
