Brief Introduction
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.
KDLD electromagnetic flow meter can be widely applied in industries like chemical, power supply, metallurgical mine, oil, water supply and drainage, paper making, pharmaceutical, food, etc..
Product Classification
Electromagnetic digital water flow meter is composed of sensor and converter. Therefore it can be classified as compact type and remote type. For remote type, the sensor and converter is connected by cable.
Based on the power supply mode, DC/AC and battery powered type.
Based on end connection difference, we have flanged connection, Flange wafer connection, Clamped connection, Threaded connection and Insertion type.
Characteristics
Variable forms for different kinds of working conditions. Compact and remote form; Flanged, flange wafer, clamped, threaded, insertion end connection; DC/AC, battery power supply.
High accuracy of ±0.5%.
Wide size range of 10mm~300mm, adapt to different size of pipelines.
Full choice of liner to accommodate conductive medium from drinking water to strongly corrosive liquid like sulfuric acid.
Measurement is not affected by the density, viscosity, temperature, pressure and electroconductibility of fluid.
Two-line LCD, able to display positive and negative instantaneous flow and accumulative flow.
No pressure loss. No moving parts.
Pulse and 4~20mA standard current output. Multiple choice of communications: RS232, RS485, Modbus, Profibus, HART, etc..
Surface mount technology(SMT) technology of converter which possesses self-check and self-diagnose functions.
Explosion-proof type can be used at relevant explosion-proof sites. IP68 remote type can be used underwater.
Each meter is factory tested and calibrated A calibration certificate is included with each meter.

Company Information--
We have been in this business for more than ten years.
Our customer satisfaction is 99. 5%.
We are located in Kaifeng, the most ancient and biggest base of flow instrument in China, which means we have full access to the most advanced technologies in this field.
We are awarded ISO9001:2008.
Our belief is "Accuracy and Attitude, Access to Customer".
Our monthly output of electromagnetic flow meters is 3000 sets.
We are able to provide electromagnetic flow meters with international standards.
Our goal is to make world wide brand.
Selection of nominal diameter--
As electromagnetic flowmeter has a high rangeability of 1500:1, the selection of nominal diameter is the same as that of process pipe;
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;
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.
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 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.
Ordering Notes--
Please read our brochure carefully to know the product model and coding rules before ordering, then choose the right product(s) and relevant code according to practical requirement. For remote flowmeter, a special cable of 10 meters is provided along. If the spacing is greater than 10 meters, guests should order according to the practical spacing. If necessary, please note:
A. the measuring medium must be conductive fluid;
B. the measuring medium should be full of the pipeline;
C. whether there is a requirement of immersing usage;
D. whether there is a requirement of providing mating flange for installation;
E. the parameters like upper limit value of flow range or the relevant flow rate that need to be set before the flowmeter ex-work;
F. please consult with us when you have any special needs.
