TOFLO FC-A40-11-B30-04 Flow Meter (Acrylic Taper Pipe) 11-B30 (3 - 30 L/min)

FAQ List:

1/ What is the flow measurement range of this model?

The FC-A40-11-B30-04 covers a flow range from 3 L/min to 30 L/min, making it ideal for medium-to-high flow cooling water applications.

2/ What fluids can I measure with this rotameter?

It is designed for clean water only. Avoid corrosive chemicals, acids/bases, or fluids containing suspended solids to prevent damage to the acrylic tube and NBR packing.

3/ How do I install the FC-A40-11-B30-04 correctly?

• Mount vertically with flow entering from the bottom port. • Ensure the meter is level and free from vibration. • Use Rc 3/4″ threaded fittings and sealant tape. • Provide straight inlet and outlet runs (≥ 5× pipe diameter) for stable readings.

4/ How do I read the flow rate?

The stainless-steel float rises until the upward fluid force balances gravity. Read the flow rate at the point where the float’s widest diameter aligns with the graduated scale on the acrylic tube.

5/ What accuracy and repeatability can I expect?

Typical accuracy is ±5 % of full-scale, with good repeatability under steady‐state conditions. For exact figures, refer to the instruction manual or factory calibration certificate.

6/ What is the pressure drop across the meter at maximum flow?

Expect a pressure loss of approximately 0.02–0.05 MPa at 30 L/min. Actual drop depends on piping configuration and inlet conditions.

7/ What are the operating temperature and pressure limits?

The meter is rated for fluid temperatures up to 40 °C and a maximum gauge pressure of 0.4 MPa. Exceeding these limits may damage the acrylic tube or seals.

8/ How do I clean and maintain the flow meter?

• Isolate and depressurize the line before removal. • Remove the float and gently rinse the tube with clean water. • Do not use strong solvents or abrasives on PMMA or NBR parts. • Inspect seals and the float for wear; replace if necessary.

9/ Can this meter handle pulsating or unsteady flows?

Moderate pulsations are acceptable, but strong pressure surges can cause float oscillation and reading instability. Install a pulsation dampener upstream if needed.

10/ Are there optional accessories or mounting hardware available?

TOFLO offers metal mounting brackets, protective guards, and calibration certificates as optional extras. Contact your distributor for details.

11/ How can I verify I have a genuine TOFLO product?

• Purchase from dealers only as QTE Technologies (qtetech.com/en). • Inspect the body for the TOFLO logo and serial number.

12/ Where can I obtain the instruction manual and datasheet?

Download the latest English manual and datasheet from TOFLO’s Download Center: https://www.tofco.jp/english/support/manual.html

Who should I contact for technical support or inquiries?

• TOFLO Corporation (Head Office): [email protected] • Local distributors (e.g., QTE Technologies (qtetech..com/en): [email protected]

13/ How do I order spare parts or replacements?

Provide your meter’s model number, serial number, and the part list to your distributor. Common spares include floats, O-rings, and packing.

14/ Are there other flow-range variants in the FC-A40 series?

Yes. The FC-A40 line includes:

FC-A40-11-B20: 2 – 20 L/min

FC-A40-11-B30: 3 – 30 L/min (this model)

FC-A40-11-B50: 4 – 50 L/min
