Premier Control Technologies Flow, pressure, level and temperature solutions
The BASIS Mass Flow controller range focuses on providing accurate and fast flow control.
Full scale flow ranges 100 SCCM to 100 SLPM with a measurement and control range of 0.1% to 100% of full scale (1000:1 turndown). Nine user-selectable gases are stored internally and this allows it to be used in a variety of industries such as producing consistent batches in glass production and mixing gases in molar ratios. The fully field selectable gases included are Air, N2, O2, CH4, He, H2, Ar, CO2 and N2O.
Accuracy of the device is gas dependent on gas but is as good as either ±1.5% of the reading or from ±0.2% of full scale. Flow repeatability is also excellent at ±0.25% of reading or ±0.05% of full scale. Control response times can be as fast as 100ms. A range of flow control scripts can be programmed using the ASCII command set and dosing and batching can be achieved through an built-in totalizer.
Device accuracy is dependent on full scale and the gas being used with the device.
See the below table for better guidance:
| Fluids | Mass Flow Accuracy 1 |
| Air, N2, O2, CH4 | ± 1.5% reading or ± 0.2% full scale 2 |
| He, H2 | ± 1.8% full scale |
| Ar | ± 1.5% reading or ± 0.5% full scale 2 |
| CO2, N2O | 100 SCCM – 2 SLPM: 1.5% reading or 0.5% full scale 2 5 – 20 SLPM: 2.0% reading or 1.0% full scale 2 50 – 100 SLPM: 3.0% reading or 2.0% full scale 2 |
1: Stated accuracy is at calibration conditions, after tare, under equilibrium conditions, includes repeatability and linearity.
2: Whichever is greater.
