Perfect for use in air consumption, air and gases flow measurement, as well as for compressed air operated tools and machines.

Flow rate volumes of gases – an important parameter in industrial processes

Actions to save energy and to assure quality in the production process are of particular importance in industrial processes. The ability to measure volumetric flow rates and volumetric flow of gases precisely is essential for this purpose. The requirements imposed on the flow sensor used for this are demanding: the sensor has to be capable of delivering precise measurements for different gases, at high overpressures and across a wide range of temperatures.

A further consideration when selecting a flow sensor is the required maintenance and associated costs. The SCHMIDT^® InLine Mass Flow Sensor Mini-IL is a low-maintenance flowmeter offering accurate and reliable measurements even in long-term installations.

The “true professional“ for industrial processes and compressed air technology

The thermal SCHMIDT^® Mass Flow Sensor Mini-IL is the perfect solution for demanding industrial applications. It can be used for a diverse range of applications, such as compressed air monitoring directly at the machine or tool, consumption recording of gases and a great deal more.

Thanks to its DN 8 and DN 12 connection sizes particularly low mass flowrates can be monitored. The Mini-IL is pressure-resistant up to 8 bar overpressure as standard.

This sensor is very easy to install: mount the sensor using the available measuring section pipes or push-in fittings for pneumatic hose connections and connect it electrically – then you are ready to go!

This sensor operates without any moving parts and employs a measuring principle that eliminates any drift or signs of ageing. This reduces the required sensor maintenance to an absolute minimum.

To activate and program the Modbus function, an Interface Splitter IL 30.2xx and a PC Programming Kit are necessary (accessory).

SCHMIDT Technology – Simply a question of better measurement
