digital insertion electromagnetic flow meter measurement instrument

Specifications

Product Name:

Application:

The KDLD-C series insertion electromagnetic flow meter, along with KD-mag series electromagnetic flow converter, makes up the inserted electromagnetic flow meter. Normally the inserted EMF are remote type, if requested, the compact type are also available.
The sensor of compact type inserted EMF is often installed at the pipeline in which the flow is measured, while that of remote type is usually mounted on the wall nearby or in instrument box with support or between instrument and controller(they are connected by a special cable).
Inserted EMF is widely applied in department like industry, agriculture, water conservation, environmental protection, water supply, etc. to measure and control the flow of various kinds of conducting liquid.

Characteristics

The characteristics of inserted EMF are the same as that of duct EMF, as follow: 
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, RS232,RS485,HART, Modbus,Profibus-dp;
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;
