The flange flow sensor is the most commonly used design. These sensors can be mounted with a rubber or PTFE (Teflon) lining. The possible material of the sensor electrode is stainless steel grade 316L, Hastelloy C, titanium, tantalum,… this can be useful to meet the requirements of each application.
The basic rubber lining is recommended for measuring the flow of the most common liquids such as wastewater, irrigation water, rainwater, slurry, cooling purposes and many other water-based liquids in various industrial processes.
The Teflon lining provides high chemical and thermal resistance as well as health safety. Therefore, they are suitable for applications in the chemical, dairy, food and other industries with similar requirements. They are typically used for measuring the flow in drinking water, wine and related products, syrup, milk, whey, beer and other food consumables. Among other things, they are resistant to cleaning lyes or acids that are used in such applications on a daily basis.
The basic dimensions and the built-in length of the flow tube comply with ISO standards. However, customized designs with other flange types (ANSI, BS, JIS, …) and custom built-in lengths can be supplied.
Flanged flow tubes are equipped with an earth electrode at the factory, while earthing rings can be included on request. This ensures flawless operation of the flow meter at all times, even when installed in plastic pipelines.
