Air Velocity Sensor 

 

 

Siemens Industry, Inc. 

Description 

This sensor is used to control the air velocity to a constant value, balance out pressure 
fluctuations (supply or exhaust air control), or to monitor the flow in air ducts. It is 
primarily used for modulating fan control in primary applications to set the basic volume 
flow. 

Application 

The QVM62.1 Sensor records the air velocity as a measured value and converts it to 
an active 0 to 10 Vdc output signal. There are three measuring ranges available:  

  0 to 16 ft/s (0 to 5 m/s) 

  0 to 33 ft/s (0 to 10 m/s) 

  0 to 49 ft/s (0 to 15 m/s). 

The sensor measures a point (that is it measures the values at a specific location in the 
flow profile. For recording the mean air velocity in the duct, the sensor’s immersion 
depth is the key measure. The immersion depth depends on the flow profile.  

The measurement principle is based on the anemometric measurement principle. The 
specially developed thin film sensing element of the QVM62.1 is almost totally 
independent from the flow direction and is insensitive to almost any kind of dirt in the 
airflow. 

Product Number 

QVM62.1 

Operation 

The air velocity sensor consists of: 

  Immersion stem with sensor head and sensing element 

  Extension pipe with fitting 

  Immersion stem end with flow direction arrow 

  Adjustable connecting flange 

  Transducer 

  Connection cable, screened, four-core, 3 feet (1 m) long
