Flow rate measuring system

Q1. Is it possible to measure flow rates of resin that contains filler?

A1. No. Filler in resin reflects light irregularly and prevents measurement.

Q2. Does the color of the resin affect flow rate measurement?

A2. Flow rates can be measured regardless of resin color (which ranges from clear to black).

Q3. Does the range of flow rate measurements depend on product plate thickness?

A3. The flow front radius varies depending on product plate thickness. This may restrict measurement time.

Q4. Are there restrictions on where sensors can be installed?

A4. The sensors are designed to measure resin flowing between parallel plates. Avoid installing sensors close to curved surfaces, ribs, or upright walls.

Q5. Can the profile of the pin tip be machined?

A5. The profile can’t be machined. This is because glass fiber is embedded inside the sensor all the way to the pin tip. Additionally, note that the sensor cannot be machined after delivery.

Q6. Can the cable be extended?

A6. No. The cable cannot be extended.

Q7. How can I check whether a sensor is functioning correctly?

A7. Please contact your nearest Futaba sales office.

Q8. Communication between the amplifier and PC isn’t working correctly.

A8. The network settings may not be correctly configured. Check the IP address settings.

Q9. No waveforms appear on the measurement screen.

A9. The sensor may have failed; communication between the amplifier and the PC may not be performed; no trigger signal is being input. A communication error may be due to poor connection. Try disconnecting and reconnecting the cable.

Q10. How can I output waveforms to an external device?

A10. A voltage output is provided with the range 1 V to 5 V.

Q11. How can I output a signal to indicate the passage of resin?

A11. Signals can be output for each channel in the form of an NPN open collector output. Connect via a 24 V DC power supply and relay.

Q12. What are the typical volumes of the data obtained?

A12. The volume of the waveform data will vary depending on sampling rate and measurement time.
