The flange flow sensor is the most commonly used design. These sensors can be fitted by a rubber or PTFE (teflon) liner. Possible material of sensing electrode is 316L grade stainless steel, Hastelloy C, titanium, tantalum,… this can be helpful to match every application requirements.
Basic rubber liner is recommended for a flow measuring of a most common liquids such as waste water, irrigation water, rain water, slurry, cooling purposes and many other liquids based on water in various industrial processes.
Teflon liner 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 basic dimensions and flowtube built-in length comply with ISO standards (see the chart below). However, custom specified designs with other types of flanges (ANSI, BS, JIS, …) and custom built-in 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 connections (DIN 11851 aseptic threading for food industry, DIN 32676 clamp, G gas threading etc.) may be specified.
