Kofloc Model 3810DSII Low-cost Mass Flow Meter with Display

The Model 3810DS II is a mass flow meter with a built-in display using a time-tested flow sensor. The 3810DS II displays total flow in addition to instantaneous flow, which is an improvement on the previous model 3810DS.

Description

The Model 3810DS II is a mass flow meter with a built-in display using a time-tested flow sensor. The 3810DS II displays total flow in addition to instantaneous flow, which is an improvement on the previous model 3810DS. Just like the 3810DS, the 3810DS II is also available with flow sensor and precision needle valve built into one piece.

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

  • Precision needle valve for controlling and monitoring very low flow rates
  • Two alarm outputs for flow monitoring
  • Analog output for instantaneous flow and pulse output for total flow
  • Compact and lightweight
  • The display is built in and the meter only requires connection to a 24-VDC power supply.
  • The meter measures mass flow and directly reads the flow.
  • There is no need for flow correction calculations based on tem-perature and pressure.
