Aleph Flow Sensors
- By use of a resin case and a reed switch detection element, we
have produced a flow sensor which is extremely simple, compact,
lightweight and economical.
- Due to the use of a reed switch, the flow sensor offers a
long life and excellent environmental characteristics. There
is virtually no damage caused by frequent and excessive switching
and secular change. It is possible to detect accurately the
amount of flowing liquid over a long period.
- Due to utilizing a built-in thermistor, it is possible to
detect temperature and liquid flow at the same time (optional).
Since it complies with food and hygiene regulations, it is suitable
for a wide range of applications.
Applications
- Control of circulating chilled water in machine.
- Control of various amounts of flowing liquid in a small-scale
process.
- Detection of amount of flowing liquid in a pump, hot water
and warm water supplies.
