Brief Introduction of electromagnetic flow meter

Electromagnetic flow meter is a kind of induction type flow instrument often used to measure, based on Faraday Law, the volume flowrate of conductive medium in closed pipelines. With microprocessor and exclusive integrated circuit, KDLD electromagnetic flow meter have the advantages of reliable performance, high accuracy, easy to use, etc.. The high speed CPU and advanced signal processing technology ensure a wide measuring range of 0.01m/s to 12m/s. The infrared remote control realize man-machine conversation, two-line LCD makes the readings and parameter setting more comprehensive and convenient.

 

The Kaide Meter KDLD Series electromagnetic flow meter is intended for fluid metering in most industries including water, wastewater, food and beverage, pharmaceutical and chemical.

The basic components of an electromagnetic flow meter are: 

The sensor/ detector, which includes the flow tube, isolating liner and measuring electrodes

The converter/ transmitter, which is the electronic device responsible for the signal processing, flow calculation, display and output signals.

Each meter is factory tested and calibrated A calibration certificate is included with each meter.

Table1 The electromagnetic flow meter and sensor

Selection of Nominal Diameter- magnetic flow meter

1.As electromagnetic flowmeter has a high rangeability of 1500:1, the selection of nominal diameter is the same as that of process pipe;

2.If there are solid particle in the measured medium, a flow rate range of 1~3m/s is recommended. If the practical flow rate is excessive yet inconvenient to adjust, the nominal diameter of the instrument is better larger than that of the process pipe, under which condition the flow rate in the measuring pipe of the flowmeter can be properly decreased and the abrasion of electrode and liner caused by the particle can be alleviated;

3.If there are sediment in the process pipe, a flow rate range of 1~3m/s is recommended. If the practical flow rate is too little, the nominal diameter of the instrument is better smaller than that of the process pipe in order to properly increase the flow rate of the fluid in the flowmeter to avoid the effect on the accuracy caused by the sediment. 

4.If the flow rate is too little yet a high-precision measurement is required, a sensor smaller than the nominal diameter can increase the flow rate to ensure high precision.

In the above 2,3,4 conditions, a reducing pipe should be jointed to both the upstream and downstream of the flowmeter. The center taper angle should be no more than 150 and there should be a straight pipe at least 5 times of the the process pipe jointed to the reducing pipe.

 

To help making lectotype, several flow values which corresponding to the certain typical flow rate are listed in the table below, any flow value could be quickly work out based on the corresponding flow rate: If a flow value is known as Q(m3/h), according to the relevant nominal diameter, check out the corresponding flow value Qwith a flow rate of 1m/s, then the flow rate can be work out through a formula as V=Q/Q1(m/s).
