SBL digital target gas flowmeter
1 Intruduction
1) Category and applications
Based on the measurement theory of flow meter, Rixin Flow Meter Ltd. Has developed a series of novel pressure influence target mode flow meters which utilize the modern sensor and computer technology. They have not only immovable characteristics such as of the Target Flow meter, Hole Board Flow meter and Turbine Flow meter, but also measure accuracy comparable to Cubage Flow meter. Since their characteristic of anti-interfere, anti-impurity, portability and reliability, they have been widely used in many fields of petroleum, chemical industry, energy, foodstuff, environment protection, water conservancy and so on. The flow meters are applicable to the following ranges::
l Diameter ,Φ15~Φ2000mm or bigger.
l High and low temperature, -196°C~+450°C.
l High pressure : 0~42Mpa.
2) Characteristics
l Measurement flow of liquid, gas, steam, ropy mediums or ambulatory mediums in low, normal or high temperature condition.
l Total quantity measurement accuracy is not less than 0.2%.
l High sensitivity, able to measure very low velocity below 0.8m/s.
l No movable part, safe and reliable.
l Wide measure range, bigger than 1:30.
l Good repeatability, generally 0.1~0.08% , fast to measure.
l Small pressure loss, only about 1/2P of Standard Hole Board.
l Able to adopt hang weight method to test the flow meter.
l Measurement range can be changed by replacing target according to need.
l LCD display.
l 4-20mA, 0-10V, impulse, and RS485 outputs.
l Easy installation and maintain.
2 Structure and Principle
1) Structure
SBL Target Mode Flow meter consists of measure tube, pressure target, sensor part (include flow strength sensor, pressure sensor and temperature sensor), transition part (variable types based on temperature, pressure), integration microcomputer (include LCD display and output part). The structure is shown below:
2) Principle
When flow medium flows through measure tube, a pressure will force on the target because of the flow kinetic energy. It is known that the pressure value forcing on the target can be expressed as
F=CDAPU2/2
where,
F — Pressure on the target
CD — Damp index
A — Area of target on axial projection to measure tube
P — Medium density
U — Mean velocity of medium
