FM-2C Peripheral

Flow Master FM-2C is ideal for flow measurement and daily inspection of flow testers: FM-2C is a standard flowmeter with a fixed pressure and flow.
Unlike float-type flowmeters, there is no need to determine the flow using a regulator valve and no trouble such as damage to the float due to inrush pressure.

Basic Specs.

FM-2C Production range

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
Pressure	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.
