Kofloc Low-Cost Metal Sealed Mass Flow Controller /Meter Model 5400

Kofloc Low-Cost Metal Sealed Mass Flow Controller /Meter Model 5400

The Model 5400 Series is a successor to the Model 3440, with enhanced basic capabilities. The appearance is similar to the conventional MFC. The sensor drive system is improved : the zero-drift is further reduced and the response in the lower range is improved . The Model 5410 Series is a mass flow meter with the same body design as that of the 5400 series.

Features :

• Control and response in each setting range are improved. • The following capability to the set voltage is improved (supporting ramping specifications). • As the valve is improved, the control resolution in each range is improved.
