Elektromagnetic flow meters with „F“ flow tube - flanged design



Elektromagnetic flow meters with „F“ flow tube - flanged design

The F (flanged) flowtube meter is the FG4000 flow meter’s standard design. You can choose a rubber or Teflon liner and from several sensing electrode materials (316L grade stainless steel, Hastelloy C, titanium, ...) to match your application’s requirements.

Basic rubber liners are suitable for applications to measure flow in common liquids such as waste water or water for firefighting or cooling purposes in various industrial processes, and similar liquids.

Teflon liners provide high chemical and thermal resistance as well as health safety. They are thus suitable for applications in chemical, dairy, food processing and other industries with similar requirements. The are commonly used to measure flow in drinking water, wine and related products, syrup, milk, whey, beer, and other food consumables. Besides other, they resist cleaning lyes or acids that are used in such applications on a daily basis.

The flange basic dimensions and flowtube installation lengths comply with ISO standards (see the chart below). However, custom specified designs with other types of flanges (ANSI, BS, JIS, ...) and custom installation lengths may be supplied.

Our flanged flowtubes are provided with an earthing electrode in factory while earthing rings can be included on request. This guarantees flawless flow meter operation at all times even for installations in plastic pipework.

We further provide our flow meters with custom specified installation sets. Custom installation lengths and connectors (DIN 11851 threading for food industry, DIN 32676 clamp, etc.) may be specified.
