The VA Master FAM540 flowmeter can be utilized for measuring the flow of liquids, steam and gases, especially when aggressive or opaque fluids are to be metered.
It is ideal for the chemical, pharmaceutical and food and beverage industries.

The flowmeters are indispensable where high pressure and / or high temperature operating conditions exist. The stainless steel primaries as well as the PTFE liner primaries are proven in many applications even under hardest conditions.
