Using  the volumetric rate of flow and the quantity of the fluid flowing through a pipe are called the liquid flow meter. The flow rate is directly proportional to the velocity of the flowing liquid and the pressure created in the conduit. Hence, the average rate of flow is determined. Various factors like viscosity and the velocity of the fluid, the diameter of the pipe, and the friction of the liquid and the inner wall of the pipe affect the flow rate. These liquid flow sensors are further simplified for its application in various fields.


High-performance Small Sized Flow Sensor


With a dimension of 10X10mm2, the liquid flow sensor produces an extraordinary performance in measuring the flow rate in a planar microfluidic medium. The miniature planar flow sensors are very efficient and cost effective in high-volume applications, consuming minimum space. It has a compact design with rear mounted fluidic ports which enable it to work efficiently in high volume fluids. The conjoined technique of the digital microsensor chip and the microfluidic chip operates the flow sensors. It is a most cost-effective method for measuring the flow rate.


Features & Applications


Following are the features of this flow sensor


  • Tremendously small stature
  • Response time is less than 30ms
  • Complete measurement is completed in the linear and digital output
  • Measures the maximum flow rate accurately
  • High chemical resistance and compatible (glass being the only wetted material) with most of the fluid medium
  • Isolated from the media during calibration
Following are the fields of application


  • Surgical equipment
  • Biomedical instrument


Due to its miniature thermal mass, the result is achieved in a very short time frame. This characteristic enables the miniature planar flow sensors to monitor the rapidly changing flow rate. In a fluidic medium, this sensor can be placed anywhere in the pipe to get the flow rate. The faults such as clogging, leaks, air bubbles, etc. can also be analyzed very easily with this small stature flow sensor.
