Product Description of smart 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.

Production steps of electromagnetic flow meter


Characteristics of electromagnetic flow meter
1. 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. 
2. High accuracy of ±0.5%.
3. Wide size range of 10mm~3000mm, adapt to different size of pipelines.
4. Full choice of liner to accommodate conductive medium from drinking water to strongly corrosive liquid like sulfuric acid.
5. Measurement is not affected by the density, viscosity, temperature, pressure and electroconductibility of fluid. 
6. Two-line LCD, able to display positive and negative instantaneous flow and accumulative flow.
7. No pressure loss. No moving parts.
8. Pulse and 4~20mA standard current output. Multiple choice of communications: RS232, RS485, Modbus, Profibus, HART, etc..
9. Surface mount technology(SMT) technology of converter which possesses self-check and self-diagnose functions.
10. Explosion-proof type can be used at relevant explosion-proof sites. IP68 remote type can be used underwater.
