SIEMENS Flow sensors offers everything needed to ensure accurate flow measurements – from flow sensors to flow switches and velocity sensors. 

Symaro flow – 
flexibleand efficient measurementof flow

Innovative sensors for all requirements

Be it the flow of liquids or the flow of air, Symaro offers everything needed to ensure accurate flow measurements – from flow sensors to flow switches and velocity sensors. Since all types of flow sensors are available with DC 0...10 V or 4...20 mA outputs, the products are very versatile.

Ruggedness, stability and longevity

The vortex flow sensors for liquid media are available in glass fiber reinforced plastic or rugged red brass. The sensors contain no moving parts, which makes them dirt-resistant and ensures an excellent media resistance. As a result, they ensure longevity and excellent long-term stability.

The flow switches are made of glassfiber reinforced plastic featuring a Reed contact, which is actuated by a magnetic field, absolutely contact-free and without a return spring. This leads to stable switching points. Depending on the model, the switches offer pressure ranges up to 25 bar without using bellows, resulting in pressure-independent switching points. This means that the switching point is solely dependent on the volumetric flow. The Symaro range of flow switches covers nominal sizes from DN 10 to DN 200.
The air velocity sensor offers three measuring ranges: 0...5, 0...10 and 0...15 m/s. Thanks to its special thin-film sensing element, the sensor operates independently of the direction of flow and is dirt-resistant.
