Dwyer GFC Series Gas Mass Flow Meter and ControllersIndonesia Industrial Parts

Dwyer GFC Series Gas Mass Flow Meter and Controllers combine a straight tube sensor with a restrictor flow element. It is available for flow ranges up to 1000 L/min and offered in aluminum or 316 SS in 1/4″, 3/8″, 1/2″ and 3/4″ sizes. Flow Range Up to 1000 L/min, Pressures Up to 1000 psi, NIST Traceable.

Dwyer GFC Series Features

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 control by comparing measured sensor signal set to flow rates
Set points can be adjusted with local potentiometers or remotely via 0 to 5 VDC or 4 to 20 mA analog signal
Actual gas flow is displayed in engineering units on a 3-1/2 digit, 90° tiltable LCD readout
Can be used with Series GFT2 Flow Totalizer for applications requiring totalization
NIST traceable certificate included

Application

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