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

Description

The Kofloc Model 3810DSII utilizes a thermal mass flow sensor to measure the mass of gas flowing through the device. This technology eliminates the need for manual temperature and pressure corrections, which are often required when using glass-tube rotameters.

The unit features a clear, 3.5-digit LCD display that provides instant flow rate information. Its compact design allows for easy installation into existing piping or equipment panels. One of the standout features of the Kofloc Model 3810DSII Low-cost Mass Flow Meter with Display is its versatility; it can be powered by either an external DC power supply or a 9V battery (optional), making it suitable for both permanent installations and portable testing applications. Despite its “low-cost” branding, it maintains an accuracy of $\pm$ 2% F.S., bridging the gap between basic visual meters and expensive high-end mass flow controllers.
