Description

Designed on the heritage base construction of the superior class bypass capillary type mass flow sensor, the 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 KOFLOC best sellers and is used by many assembly manufacturers as a substitute for the existing float type (tapered pipe type) flow meter.

The natural environment is preserved through the balance of solids, liquids and gases that exist on the earth. However, human civilization has caused pollution that has greatly damaged our environment. The task of the present generation is to restore our environment to its natural healthy state. And this is also the greatest challenge for 21st century science and technology.

KOFLOC's corporate motto is "A Scientific Approach for Fluids." In other words, we create products that scientifically measure and control the balance of liquids and gases. We trust that through our work we are making a contribution to the regeneration of the environment and to the establishment of a prosperous society.

Features

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