Kofloc Low-cost Mass Flow Sensor MODEL 3810S SERIES

Diposkan pada Oktober 17, 2016Juni 13, 2017 oleh Yugo Nugroho Boyolali

Low-cost
Mass Flow Sensor

MODEL
3810S SERIES

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.

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.
