Bios
Gas flow benches offer practical engineered solutions for calibration
of gas flow measurement
devices using proven DryCal® technology. Bios flow benches are
configured to provide the stable flow
critical to the calibration process. The gas flow benches are configured
for specific applications, using different components
to connect the gas source,
regulate pressure, control the flow, and direct the flow to a specific
device being calibrated against a
DryCal® standard. |

Bios Gas Flow
Bench Configurations |
| 100-025 MFC Flow Bench |
A Gas Flow Delivery System used for calibrating Mass
Flow Controllers (MFCs) where the exhaust of the MFC is at atmospheric
pressure. Includes an on-off valve, precision pressure regulator,
pressure gauge, and MFC mounting stand. This flow bench is designed
for a maximum gas flow of 50 Liters per min. Requires customer connection
to a gas source of approximately 100 psi. For use with the Met Lab
Series 5-500 sccm |
| 100-028 Back Pressure Module |
This add-on Module allows calibration of device under test (DUT)
at back pressure of up to 60 PSI. Includes a Pressure gauge and a
Back Pressure Regulator. Requires (100-025 or 100-030H/L). This flow
bench is designed for a maximum gas flow of 50 Liters per min. For
use with the Met Lab Series. 14-15.9 PSI |
| 100-029 Calibration System FTS Flow Bench |
Calibration
Station- Definer 110/FTS calibration system includes: Gast pump,
digital manometer and flow bench. In addition, an ML-500
is required for laboratory calibration of flow transfer standards
such as the Bios Definer 110 or Chinook Engineering Streamline FTS.
The flow bench includes an adapter and needle valve. This calibration
station is designed for a maximum gas flow of 30 Liters per min.
For use with the Met Lab Series. |
