Rixin SBL-target flow meter compare with WELKIN-WFV target flow meter:
SBL digital target flow meter is improved from traditional flow meters and can take place of them, such as turbine, electromagnetic, ultrasonic, mass, volumetric, vane-wheel, by-pass, orifice, differential pressure flow meter. It was widely used in fields of gas, natural gas, petroleum industry, chemical engineering, energy industry, food industry, environmental protection and water conservancy etc. High accuracy, anti-interfere, anti-impurity, anti-acid, corrosion resistant, portability, etc.are its features.
Characteristics
Measurement flow of liquid, gas, steam, ropy mediums or ambulatory mediums in low, normal or high temperature condition.Total quantity measurement accuracy is not less than 0.2%.High sensitivity, able to measure very low velocity below 0.8m/s.No movable part, safe and reliable.Wide measure range, bigger than 1:30.Good repeatability, generally 0.10.08% , fast to measure.Small pressure loss, only about 1/2P of Standard Hole Board.Able to adopt hang weight method to test the flow meter.Measurement range can be changed by replacing target according to need. LCD display.4-20mA, 0-10V, impulse, and RS485 outputs→remote control.Easy installation and maintain.anti-interfere, anti-impurity, anti-acid, corrosion resistant, portability

Description:
(1) Description of flange
Short connection flange shall execute relevant technical requirements in state standard GB/T9115.1~9115.4-2000, or special standard such as American or European standard as required by user.
(2) Description of structure
a. For actual dimensions of high temperature or temperature/pressure compensation inserted type flowmeter, ex-factory (order) status shall govern.
b. When media temperature of high temperature type flowmeter is >200, the instrument must be installed up-side-down and horizontally. The design shall consider sufficient mounting space.
c. If the media flow up-down or down-up, for ordering, please note: right view, left view (showing gauge head).
In this design, only fixed inserted type is provided; if telescopic online removable type is required, particular size shall be determined with manufacturer.
