The IST AG Out of Liquid sensor utilizes the reliable and proven thermal mass flow measuring principle and is specially developed for flow applications with aggressive media. The sensor provides the flexibility of easy adaption in an application and at a lower cost. Measuring flow directly in a liquid channel has proven a difficult task without dramatically shortening the lifetime and damaging the sensor. The Out of Liquid sensor offers the possibility to create no-flow / flow switches. It also offers the possibility of an extremely accurate measurement. A heater and a temperature sensor chip, both with backside metallization, are soldered on the stainless steel flow channel providing an excellent thermal contact with the liquid without being in direct contact with the liquid, meaning even aggressive liquids are suitable for this sensor.

Further advantages of the Out of Liquid flow sensor include:

• High chemical resistance
• No contact between sensor and liquid
• Simple flow switches possible

The IST AG Out of Liquid flow sensors are optimal for measuring liquid flow in aggressive liquids.
