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.

Dwyer Flow Switch
Model no. V4-SS-2-U-AT
Vane-Operated Flow Switch: Field Adjustable – Dependable Protection Against Flow Variation or Stopping in Pipelines for Fluids, Gases and Flowing Solids.
Features
- Leak proof body machined from bar stock
- Weatherproof, designed to meet NEMA 4
- Explosion-proof
- Installs directly and easily into pipeline with a threaded branch connection, tee, or flange
- Can be used in pipes 1-1/2″ and up
- Electrical assembly can be easily replaced without removing the unit from installation so that the process does not have to be shut down
- High pressure rating of 1000 psig (69 bar) with the brass body and 2000 psig (138 bar) with the 316 SS body
- Unique magnetically actuated switching design gives superior performance
- There are no bellows, springs, or seals to fail
- Instead, a free-swinging vane attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm
Applications
- Protects pumps, motors and other equipment against low or no flow
- Controls sequential operation of pumps
- Automatically starts auxiliary pumps and engines
- Stops liquid cooled engines, machines and processing when coolant flow is interrupted
- Shuts down burner when air flow through heating coil fails
- Controls dampers according to flow
