Flow Indicator، Flow Switch و Flowmeter ابزارهایی هستند که در صنعت برای اندازه‌گیری و کنترل جریان سیالات مورد استفاده قرار می‌گیرند. اما هر کدام از این ابزارها وظایف و کاربردهای خاص خود را دارند:
Flow Indicator (نشانگر جریان): نمایش بصری جریان سیال در یک لوله یا خط لوله.
Flow Switch (کلید جریان): تولید سیگنال الکتریکی در صورت وجود یا عدم وجود جریان سیال.
Flowmeter (سنجش جریان): اندازه‌گیری دقیق حجم، کمیت یا سرعت جریان سیال با استفاده از تکنولوژی‌های مختلف.
به‌طور خلاصه، Flow Indicator جریان سیال را به صورت بصری نشان می‌دهد، Flow Switch کنترل جریان را با تولید سیگنال الکتریکی انجام می‌دهد و Flowmeter اطلاعات دقیقی از جریان سیال به ارائه می‌کند. هر کدام از این ابزارها در بستر محیط‌ها و نیازهای مختلف صنعتی استفاده می‌شوند.

Mass Flow Controller Model 5853
To truly control any process, you must precisely measure what is happening — in the feedline, in the chamber, at every point — then use that information in real time to keep the process precisely on-target and productive.
As the global leader in precision fluid measurement and control, mass flow meter manufacturer Brooks Instrument continues to innovate thermal mass flow technology. From thermal flow sensors and mass flow metering systems, we continually launch new products and enhance existing systems to unlock new levels of thermal mass flow measurement precision, responsiveness, accuracy and repeatability.
Key reasons why our mass flow sensors are the most widely used worldwide include:
- Industry-best range of digital mass flow meters and other products to meet widest application needs
- MultiFlo™ technology allows one device to change gas types and ranges without removing the device from the system and improving actual process gas accuracy. MultiFlo™ is offered for use with thermal thermal mass or flow sensors
- Complete product range includes both elastomer sealed and metal sealed options for thermal mass flow sensors and coriolis mass flow sensors
- Ultra-high purity mass flow sensors and devices engineered to satisfy thin film, semiconductor and other high-tech industry requirements

Krohne DW 181 Mechanical Flowmeter
DW18 Krohne is an inline flow controller for locally indicating the flow of homogeneous clean liquids without auxiliary power. It is suitable for horizontal or vertical pipes. The flo controller can have G or NPT threaded connections with sizes ranging from sup>3⁄4…2″. The measuring tube and connection are made of either bronze or stainless steel (1.4404 /316 L). Two types of indicator are available: a linear scale with up to two alarm positions at the top and bottom of the indicator or a dial.
The DW 181 is particularly suitable for cost-effective flow detection in various applications where high accuracy is not required. It can deal with flows of up to 30,000 l/h or 132.09 GPM (US). There is also a high-temperature version on offer for operating conditions up to +300°C / +570°F. The DW 181 is available as non-hazardous, intrinsically safe and explosion-proof version.
