The flow sensor type 230 has a rugged construction of red brass. With no moving parts the flow sensor is not sensitive to debris, has marginal pressure loss and high accuracy.
Alternatively, are versions with integrated temperature measurement is available.

1.  Flow measuring with voltage, current
 or frequency output
2. Temperature non-sensitive measuring
 principle
3. Excellent media resistance (measuring
 element not in contact with the
 media)
4. CE conformity
6.  Wide application temperature range
7. Marginal loss of pressure
8  Measuring element not sensitive to
 debris
9 .Zinc free red brass housing
