HORIBA STEC提供多種不同類型的氣體質(zhì)量流量控制器以滿足客戶不同的需求。所有產(chǎn)品都擁有高精度、快速響應(yīng)的特性。多種不同類型的氣體質(zhì)量流量控制器皆擁有寬泛的流量范圍,客戶可選擇適合的閥門類型。我們可提供三種閥門,客戶可選擇熱式閥門、電磁線圈閥門、或者壓電陶瓷閥。同樣我們也可提供多種不同的通訊方式,包括模擬式、數(shù)字式、DeviceNet?,以及PROFIBUS?,RS485,cc-link,(取決于產(chǎn)品型號)。我們產(chǎn)品的流量范圍可覆蓋微量流量直至更大流量。
HORIBA STEC質(zhì)量流量控制器是一種計(jì)測和控制流體流量的裝置。流體的流量計(jì)測通常可分為體積流量和質(zhì)量流量。體積流量由于受到計(jì)測時環(huán)境溫度和壓力的影響,如需要準(zhǔn)確測定時,必須對溫度和壓力進(jìn)行調(diào)整。而質(zhì)量流量計(jì)在測定流體質(zhì)量的時候,不容易受到環(huán)境溫度和壓力等外在因素的影響而能準(zhǔn)確地進(jìn)行流體測量。在必須對流量進(jìn)行精確計(jì)測和控制的領(lǐng)域,質(zhì)量流量控制器被廣泛的使用,例如半導(dǎo)體工業(yè)、太陽能光電工業(yè)和微電子加工制造業(yè)等

The SF-1U/2U combines precision volumetric
tubing with a soap film detector (patented) that
allows it to measure the flow of any type of gas
accurately. It measures the amount of time required
for the movement of a soap film through a portion
of the volumetric tubing (of a standard volume), and
determines the gas flow rate using that time value
along with measured values for atmospheric
pressure and temperature during the relevant time
period. There are four different volumetric tubing
units (VP series), suitable for different gas flow
levels. The SF-2U features an internal atmospheric
pressure sensor.
The SF series of precision film flow rate meters use a combination of precision
volumetric tubing and a soap film detector (patented) to measure the flow rate of
any type of gas.
When the start switch is turned on, the film link begins to work, and a soap film is
generated at the opening of the volumetric tubing. The soap film is moved up into
the volumetric tubing by the flow of the gas, and the time it takes the film to pass
two detectors installed a set distance apart from each other is measured. The value
for the volume between the two detectors can be determined precisely, and that
volume, the time it took the film to pass between the detectors, the temperature,
and the atmospheric pressure are read into a microcomputer. Calculations to
correct for vapor pressure (see formula) are performed automatically, and the flow
rate, converted to a standard 25°C and 1013 hPa, is displayed
