Digital water magnetic flowmeter,electromagnetic flow meter
1.Introduction of Digital water magnetic flowmeter water
Intelligent KDLD low cost magnetic water flow meter measuring tool / instrument is manufactured with the modern technology of electromagnetic flow, the measuring principle of which is based on the electromagnetic induction law of Farady. It is mainly used tomeasure the volume flow of conducting liquid and slurry in closed pipeline, applicable to industries like chemical, power supply, metallurgical mine, oil, water supply and drainage, paper making, pharmaceutical, food, etc..
 
2. Features of Digital water magnetic flowmeter water

a) the measurement is not affected by the density, viscosity, temperature, pressure and electroconductibility of fluid;
b) there are no obstacles or loss of pressure in the measuring pipe, low requirements for straight pipe;
c) the nominal diameter is from DN3 to DN3000 for this series. Multiple choices are available for the liner of converter and the material of electrode;
d) adopt a novel way of excitation, low power consumption, stable zero point and high accuracy. The flow rangeability is up to 1500:1;
e) converter and transducer together can be made up into two forms of flowmeter: compact-type and remote-type;
f) a 16-bit high-performance microprocessor is adopted into the converter, it has a 2*16LCD displayer, the parameters are easy to set and the programming is reliable;
g) the measuring system in the flowmeter is bidirectional and with three integrators inside: positive total, reverse total and difference value total. The positive total and reverse total are both displayable. It also has multiple ways of output: electric current, pulse; digital communication, HART;
h) the mounting technology of converter is surface mount technology(SMT) which possesses self-check and self-diagnose functions;
i) the structure of transducer with rubber liner and transducer with polyurethane liner are both submerged;
j) the explosion-proof instrument can be used at relevant explosion-proof sites;
