VA METAL TUBE Flowmeter
-------------------
Manufacturer: SMC(USA)
Model: ALVAMT Series
Introduction:
SmartMeasurement’s ALVAMT (commonly known as a metal tube flowmeter) is a rugged variable area meter (rotameter) that is ideal for high pressure, high temperature and other demanding flow applications where safety is a concern. Features include: globally-recognized approvals for use in hazardous environments; analog and digital LCD local display options, multiple options for process connection; several available materials of construction for metering of aggressive fluids and corrosion resistance; and HART enabled 4-20mA output to provide for remote monitoring and control.
The ALVAMT's low cost and excellent repeatability makes it a good choice for batching applications. It is also a good choice in applications where no power supply is available as versions without electronic output do not require any power. The ALVAMT's low-pressure drop provides additional value by allowing for economical pump selection.
Features:
- Excellent low-flow performance
- Versatile design may be used for gas, steam, and liquids
- Low pressure loss for gas and steam applications
- Suitable for high pressure and high temperature applications
- Turn-down ratio of 10:1
- Local indication and intelligent remote LCD display
- Easy-to-read analog pointer style indicator
- Intrinsically safe & explosion proof for hazardous area applications
