IST mass flow sensors can be found in various flow switches, controllers or meters as well as the heart of leakage or bubble detection systems. Our mass flow sensor elements utilize thermal measurement principles known for their long-term stability and ease of integration into any application with a known fluid. From the physical sensor level to a ready-to-use digital module, build your custom flow sensor with IST AG. Evaluation kits are available with the most common flow sensors.

Flow Sensor MFS

Using accurate thin-film heating and temperature sensing structures ensures high sensitivity with a very compact and robust sensor. The dynamic range of anemometric gas flow sensors ranges up to 100m/s covering operational temperatures up to +400°C.

The FS7 (link to product in shop) is our most widely used gas flow sensor for applications with a known flow direction.  The option of a simple housing keeps assembly into various flow channels easy to handle, and  its excellent long-term stability makes the flow sensor ideal for control and safety applications.

With FS2 and MFS02 sensors, flow direction can be monitored along with the measured mass flow. Their extra wide dynamic range make them excellent candidates for applications ranging from medical microfluidics to large scale HVAC systems. Different assembly options with cable, carrier PCB or custom housing ensure optimal sensor positioning.

SFS01 is a silicon based calorimetric flow sensor with an ultra-fast response time suitable for medical and industrial flow applications with low flowrates and a mild temperature range.

OOL Flow sensor

OOL stands for out of liquid and is a flow-through sensor with stainless steel as single wetted material. This robust anemometric sensor is suitable for various aggressive liquids including coolant mixtures, oils containing particles or cleaning chemicals used in CIP systems.

The highly accurate and reliable OOL liquid flow sensor is suitable for measuring liquid flow in aggressive liquids. 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 it. For fast measurement results, there is an out of liquid demo board available.

Flow Modul OOLmass-flow-modul

OOL Flow meter is a digital module continuously monitoring mass flow and temperature. It comes in a sturdy housing with a factory calibration as a plug-and-play sensor solution.

IST's leakage detection Flow OOL-module is equipped with a highly sensitive flow sensor component, which can detect the smallest liquid flow quantities with an accuracy of <3% F.S. and a repeatability of < 0.3 % F.S. (value for DI-H2O in temperature range of +5 to +50°C) in a response time of 500 ms.

Suitable for a wide variety of applications from cooling circuits, dosing pumps, white goods, CIP systems for food industry, agricultural machines, industrial wet vacuum cleaners, to gear oil used in metalworking and mining, IST AG's new thermal OOL mass flow meter can be easily integrated into new or existing industrial systems.
