Product Applications

Gas flow measurement
Gas flow control
Operating pumps and valves
Process equipment
Vacuum processes
Glass and metal coating
Film depostition

Provides high accuracy and repeatability
Flow rates are virtually unaffected by temperature and pressure variations
Utilizes an electromagnetic valve and PID electronics to maintain continuous controlby comparing measured sensor signal set to flow rates
Set points can be adjusted with local potentiometers or remotely via 0 to 5 VDC or 4to 20 mA analog signal
Actual gas flow is displayed in engineering units on a 3-1/2 digit, 90° tiltable LCDreadout
Can be used with Series GFT2 Flow Totalizer for applications requiring totalization
NIST traceable certificate included
