DIGITAL VARIABLE AREA FLOW Controller: MASS-VIEW®
THE INTELLIGENT MASS FLOW Controller
The MASS-VIEW® series operate on the principle of direct thermal mass flow measurement. A major advantage of using this type of sensor is that the instruments measure direct mass flow, without the need for temperature and pressure correction.
The MASS-VIEW® has compared to conventional VA meters high accuracy and rangeability (up to 1:100). The 10 pre-installed gases eliminate the need to recalibrate for different gases and therefore reduce the cost of ownership. For your convenience, we also have our flow ranges in other flow units.
Flow control is achieved by keeping the pressure drop across the needle valve constant. With a varying upstream pressure, the flow will nearly be constant.
Only need to measure the flow? MASS-VIEW Meters Want to regulate the flow? MASS-VIEW Regulators
