FM-2C
Customized to the specified pressure and flow.
Use as a standard for testing and comparing flowmeters.
● Use as a flow master for measuring deviation flow. (Test for ventilation and bore diameter of holes)
Customized to the desired flow. Use it as a reference instrument.
When placing an order, specify the test pressure and flow in the following ranges.
Test pressure | Flow | |
Vacuum | -89 to -50.1 kPa | 200 mL/min to 5 L/min |
-50 to -21.1 kPa | 100 mL/min to 15 L/min | |
-21 to -10.1 kPa | 100 mL/min to 10 L/min | |
-10 to -1 kPa | 50 mL/min to 3 L/min | |
Pressure | 1 to 10 kPa | 50 mL/min to 3 L/min |
10.1 to 21 kPa | 100 mL/min to 10 L/min | |
21.1 to 51 kPa | 200 mL/min to 15 L/min | |
51.1 to 100 kPa | 0.3 L/min to 25 L/min | |
100.1 to 150 kPa | 0.5 L/min to 35 L/min | |
150.1 to 200 kPa | 0.5 L/min to 45 L/min | |
201 to 250 kPa | 0.5 L/min to 55 L/min | |
251 to 300 kPa | 0.5 L/min to 65 L/min | |
301 to 350 kPa | 0.5 L/min to 70 L/min | |
351 to 400 kPa | 0.5 L/min to 80 L/min |
For specifications outside the production ranges, a request for quotation (RFQ) will be required.
201 to 209 mL/min is outside the standard production range.
2.01 to 2.09 L/min is outside the standard production range.
Minimum unit of test pressure (kPa)
Test pressure | Range | Minimum unit |
Vacuum | Down to -89 kPa | 0.1 |
Pressure | Less than 200 kPa | 0.1 |
200 kPa or more | 1 |
Accuracy (Difference from the required flow) & Minimum unit
Required flow | Difference from the required flow | Minimum unit |
50 mL to 200 mL | Accuracy (Difference from the required flow): Within ±10% | 1 mL |
0.21 L to 2.00 L | 0.01 L | |
2.1 L to 80 L | 0.1 L |
For the flow above 200 mL/min, specify in units of L/min.
