Typical applications

Control of suction flow rate in air volume samplers, gas detectors, etc.

- Measures the mass flow rate intake of the pump without effects from temperature fluctuation or changes in atmospheric pressure.
- Operates on battery power on handheld equipment.

Control or monitoring of supply flow rate for oxygen concentrators, etc.

- Useful for control of oxygen flow rate from compressor, without effects from fluctuation in room temperature or altitude.
- Useful for replacing from a float meter.

Monitoring of purge rate or cooling flow rate for wire bonders, etc.

- Measures flow rate of air supplied to eliminate heat haze.
- Measures flow rate of nitrogen supplied to prevent oxidation.
- Useful for replacing from a float meter or pressure gauge.

Pick-up and placement detection of miniature electrical or optical devices.

- Can be installed close to the pick-up nozzle.
- Fast response is suitable for pick-up detection.
- Measures slight differences in flow rate which cannot be detected by pressure.
- Not affected by fluctuation in suction pressure, thanks to mass flow measurement.
- Clogged or crushed nozzle is detectable by analog output.

Accessories

Multi channel indicator model MCW401

Designed for remotely display unit with up to 4pcs MCS100.
It also produces open collector switch output.
Additionally, by means of RS-232C communication, PC or PLC can be used to set parameter and to view instantaneous flow value and switch status of each channel. 4 types of “Window comparator mode” suitable for pick-up & placing applications and “Hysteresis mode” suitable for general flow monitoring, as switching operation.

Model MCW401 can be applied with below MCS100 models.

- MCS100A100, MCS100A104, MCS100A108, MCS100A112, MCS100A120, MCS100A128
