The SERIES GFM2 Gas Mass Flow Meter is an ideal choice for the measurement of flow rates of a wide variety of gases. Unit can be calibrated for a variety of gases with user selectable 0 to 5 VDC or 4 to 20 mA and two relay outputs and programmable totalizer that indicates total gas quantity.California Residents:  Click Here for Proposition 65 WARNING.

The Series GFM4 Gas Mass Flow Meter is an ideal choice for the measurement of flow rates of a wide variety of gases. This multi parameter flow meter supports various functions such as flow totalizer, flow, temperature, and pressure alarms, and is available in a choice of 0 to 5VDC, 0 to 10VDC, or 4 to 20 mA output signals. Standard LCD and four button keypad allows easy access to the many features of the GFM4. Digital interface operates through available RS-485 or RS-232, providing access to internal data parameters and multi-drop capability of up to 255 units (RS-485 only). Set alarms remotely via digital interface for flow, pressure, and temperature to alert user of high or low thresholds being exceeded. With a high ±1% FS accuracy and ±0.25% FS repeatability, the GFM4 is the optimal choice in gas flow metering and monitoring. The GFM4 comes with a NIST traceable certificate.

The Series GFM3 Gas Mass Flow Meter is an ideal choice for the measurement of flow rates of a wide variety of gases. This digital flow meter features a 12-digit totalizer for total gas volume indication, and is available in the choice of 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mA output signals. Standard LCD and four button keypad allows easy access to the many features of the GFM3. Digital interface operates through available RS-485 or RS-232, providing access to internal data parameters and multi-drop capability of up to 255 units (RS-485 only).

Program, record, analyze, and control flow rates of various gases with Series DMF Digital Mass Flow Controller. Controllers are designed with straight tube sensors with restrictor flow elements to ensure laminar gas flow for accurate and repeatable results. Series DMF are unaffected by temperature and pressure variations.Controllers can be programmed for various control functions including flow set point, totalizer, stop totalizer, totalize from preset flow, stop and preset total, auto zero, and more. Auto zero feature utilizes an automatic balancing circuit that virtually eliminates drift of zero and span. In addition, Series DMF controllers have two dry contact closures to operate pumps, valves, or other process equipment.The Series DMF features an auto tune function to optimize control response for a specific gas under actual process conditions. Self diagnostic tests are run at power up to ensure the controller is in optimum working condition. Calibration information for up to 10 gases and conversion factors for up to 256 different gases are stored in memory. High and low gas flow alarm limits are programmed via RS-485 interface. Software supports programmable flow modes, allowing execution of custom programming of up to ten steps.
