HORIBA STEC提供多种不同类型的气体质量流量控制器以满足客户不同的需求。所有产品都拥有高精度、快速响应的特性。多种不同类型的气体质量流量控制器皆拥有宽泛的流量范围，客户可选择适合的阀门类型。我们可提供三种阀门，客户可选择热式阀门、电磁线圈阀门、或者压电陶瓷阀。同样我们也可提供多种不同的通讯方式，包括模拟式、数字式、DeviceNet™，以及PROFIBUS™，RS485，cc-link，(取决于产品型号)。我们产品的流量范围可覆盖微量流量直至更大流量。
HORIBA STEC质量流量控制器是一种计测和控制流体流量的装置。流体的流量计测通常可分为体积流量和质量流量。体积流量由于受到计测时环境温度和压力的影响，如需要准确测定时，必须对温度和压力进行调整。而质量流量计在测定流体质量的时候，不容易受到环境温度和压力等外在因素的影响而能准确地进行流体测量。在必须对流量进行精确计测和控制的领域，质量流量控制器被广泛的使用，例如半导体工业、太阳能光电工业和微电子加工制造业等

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
