Low-cost Mass Flow Sensor
|      Features     |     Standard Specification     |     Harness Layout     |

Designed on the heritage base construction of the superior class bypass capillary type mass flow sensor, Model 3810S Mass Flow Sensor centers the focus on economy through a thorough effort towards streamlining with the view to built-in applications. The series is one of the best sellers and is used by many assembly manufacturers as a substitute for the existing float type(tapered pipe type)flow meter.

  • A low-cost,still,full-fledged sensor based on a happy combination of the constant-current temperature difference detection type with the bypass capillary type
  • A large cost reduction makes Model 3810S almost rival any exsiting float type flow meter in price.
  • 0 to 5-VDC analog flow outputs provide various applications such as measurements recording,control and alarm issuance.
  • Because the sensor is mass flow type, the user needs no troublesome calculations for flow correction due to the effects of temperature and pressure.
