1. General Description
ZJK series magneto-electric intelligent flow-meter is taking the technique of magneto-electric digital signal testing, it has the advantages of high vibration resistance\high sensitivity and low power. It can be widely used for vortex-shedding flow measurement in oil\chemical\metallurgy\brewing\printing and dyeing\medical\food environment protection and water supply and drainage industries.
2. Major Features
It is designed with dual power supply, it is internally equipped with a 3.6V lithium battery and externally equipped with DC24V power supply, the power of these two kinds can be supplied at the same time.
It is designed with intelligent integration with a powerful, function, field display and convenient for users′ reading and for easy modification of parameters.
It is for overall signal output with standard two-wire system of 4~20mA output current and for impulse output and RS-485conmmunication (added based on actual needs).
It has a good ability of anti-libration and anti-interference.
The transducer is made with stainless steel for anticorrosion and it is long usage life without internal movable parts.
It is low lower-limit flow, with wide measurement range and high measuring precision.
It can be calibrated in oilfields through a section of plane set on the tubular shell of the flow-meter.
The vortex generator is dismountable to avoid the abandonment of the whole flow-meter and stop the operation of system, and its cleaning and displacement can be carried out in the field.
