Dial-A-Gas & Pilot Module Interface

Control, Independence and Flexibility for Your Mass FLow Controller 

All 100 Series mass flow meters and controllers are available with our innovative and user-friendly Pilot Module, a front-mounted or hand-held control readout device that gives you the ability to Dial-A-Gas® .  Dial-A-Gas results from a patented, inherently linear Laminar Flow Element (LFE) design, advanced platinum sensor technology, and Sierra’s proprietary frictionless-hovering control valve technology. 

Adjust the Following with Dial-A-Gas:

• Gas type
• Setpoint value
• Setpoint source
• Set zero, span and full scale for each of 10 different gases independently to accommodate unexpected application or system design changes
• Modify engineering units
• Valve state (open, closed, automatic)
• Output signals: RS-232, RS-485, 4-20mA, 0-5 VDC, 1-5 VDC, 0-10 VDC

With every instrument, Sierra ships free user software that allows the customer to perform all the Dial-A-Gas unctions of the Pilot Module from their computer.  The following ten gases make up the standard Dial-A-Gas® feature of every Smart-Trak instrument; up to nine alternate gases may be substituted.
