Jing Chuan JC- LB Smart Target Flowmeter

I. Product Overview:
Jing Chuan new generation of intelligent target flowmeter, set the flow rate, temperature, pressure detection functions in one, the use of advanced microcontroller technology and capacitive pressure sensor, the product no moving parts, anti-vibration, anti-impurity, anti-jamming capability; with Simple, easy to install, maintenance-free, self-test failure, a series of characteristics and low operating costs. has been widely used in semi-water gas, coke oven gas, heavy oil, residual oil metering, asphalt, liquid paraffin, toluene, sulfuric acid, natural gas, methane as well as other special media measurement chlorides, flue gas, chlorine gas, sewage, clean water, etc., to solve the difficult flow measurement industry for years.
Second, the principle:
When the medium flows in the measuring tube, the kinetic energy of the Target by its own generating pressure, the force generated on the target plate, so that the target plate displacement trace, the size of the force proportional to the square of its velocity and media ., Target suffered by the target lever force transmission, the elastomer sensor produces small changes, thus breaking the bridge balance SMD capacitors generation and traffic on the target plate voltage signal corresponding to the force: the fluid flow Impact characteristics of voltage squared flow and electricity generated is proportional to the bridge.
F = Cd`A`ρ`V2 / 2
Where F: Target suffered force
Cd: fluid resistance coefficient
A: Target axial projection area of ​​the measuring tube
ρ: density of the medium conditions
V: medium in the measuring tube characteristic velocity
Target suffered the force transmitted through the target rod elastomer sensors produce small changes, through circuit switching, outputs a corresponding electrical signal.
Third, intelligent target flowmeter Features:
1, the entire instrument in the design with no moving parts, plug-in structure, easy disassembly;
2, can choose a variety of corrosion and high temperature resistant materials (such as Hastelloy, titanium, etc.);
3, the machine can do no dead ends, fully sealed (welded form), no leakage point, can be resistant to 42MPa high pressure;
4, instrument features self-test procedures, failure phenomenon glance;
5, the sensor is not in contact with the measured medium, there is no wear and tear parts, the use of safe and reliable;
6, may be the use of dry calibration method, which uses weights hanging weight method calibration can be done one-button operation.;
7, with a variety of installation methods to choose from, such as selecting the online plug-in, low installation costs;
8, with integrated temperature and pressure compensation, direct the output quality or standard side;
9, with an optional low-cut, non-linear correction, filter time option;
10, can accurately measure a variety of normal, high temperature of 500 degrees -200 degrees temperature conditions of the gas and liquid flow;
11, measurement accuracy, precision can reach 0.2%;
12, repeatability, generally 0.05 to 0.08%, rapid;
13, pressure loss, only the standard orifice 1/2 • P about;
14, anti-jamming, anti-impurity capacity particularly strong;
15, according to the actual need to be replaced Baffles (target plate) and change the flow range;
16, low-power battery-site display that can be read online direct indication, the display can be read simultaneously instantaneous and cumulative flow rate and percentage bar graphs;
17, easy to install, easy to maintain;
18, multiple output format, various parameters can be remote;
19, anti-vibration and strong, within a certain range can be measured pulsatile flow;
