Kofloc Model D3810 Digital Mass Flow Meter

Description

The Kofloc Model D3810 Digital Mass Flow Meter represents a significant leap from mechanical flow indicators. It features a high-sensitivity thermal sensor and a bypass capillary system. As gas passes through the sensor, it detects the heat transfer proportional to the mass flow rate.

The D3810 is specifically designed for users who require an “all-in-one” solution. It houses the sensor, the processing electronics, and a 3.5-digit LCD display within a single compact body. This eliminates the need for external readout units. Furthermore, the Model D3810 provides a linear analog output signal (typically 0–5V DC), allowing it to communicate simultaneously with a local operator and a remote PLC or data logging system. Its robust construction and high accuracy of $\pm$ 2% F.S. make it a dependable workhorse for modern gas handling systems.

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.
