1、Overview JGLG Series orifice flowmeter is to measure the differential
pressure flow generating device, with a variety of differential
pressure gauge or differential pressure transmitter can measure the
flow of various fluids in the pipeline. Throttling device orifice
flowmeter, including ring chamber orifice, nozzle and so on.
Throttling device orifice flowmeter and differential pressure
transmitter supporting the use of measurable liquid, steam, gas
flow, orifice flow meters are widely used in petroleum, chemical,
metallurgical, power, light industry and other sectors The fluid filled pipe, when they flow through the pipeline
throttling device, the beam will be at the cutting device cutting
pieces of partial contraction, so that the velocity increases,
static pressure is low, so in cutting pieces will be produced
before Pressure drop, the pressure difference, the greater the flow
of media flow, resulting in cutting pieces before and after the
greater pressure, so by measuring the differential pressure orifice
flow meter to measure the size of fluid flow. This measurement
method is based on law of conservation of energy and flow-based law
of continuity
Intelligent throttling device (orifice meter) is the set of flow,
temperature, pressure detection in one, and can be temperature and
pressure compensation for a new generation of automatic meter, the
orifice flowmeter uses advanced computer technology and micro-power
New technologies, powerful, compact, simple, easy to use 2、Characteristics Throttling device orifice flowmeter structure easy to copy, simple,
solid, stable performance, reliable, long-term, low price Plate calculated using international standards and processing Orifices wide range of applications, all single-phase flow can be
measured, some mixed-phase flow can also be applied Standard do not practical flow throttling device calibration, you
can put into use A body orifice meter installation easier, no impulse control,
differential pressure transmitter can be directly connected and
pressure transmitters Intelligent orifice flowmeter characteristics Smart differential pressure sensor using monocrystalline silicon Accuracy, improve self-diagnostic function Smart Intelligent orifice flowmeter orifice flowmeter can be
self-programmed to adjust its range Smart meters can display total orifice flow, instantaneous flow,
pressure, temperature With online, dynamic full compensation, the smart orifice flowmeter
also has a self-diagnosis, self-set range With a variety of communication interfaces High stability Wide measuring range, greater than 10:1 Intelligent orifice flowmeter technology indicators Precision:±0.075% High stability: better than 0.1% FS / year High static pressure:40MPa 5 years of continuous work without adjustment Negligible temperature, static pressure effects Resistance higher than the pressure
