Specifications and Product Details:

Dynameters ultrasonic water flow meter utilize State-of-the-Art transit-time digital signal processing technology and cross-correction technology, feature high reliability, good stability and high accuracy in all industrial environments. The meter with rugged construction has no moving parts and does not require external power to operate the transmitter display. The self contained battery has a life of 6 yeas. An optional externally power supply for 4-20mA, OCT, RS232/485 output is available. The configurations of meter parameters are completed in the factory and the only thing left to do is to install them and take readings. The meters have the same installation dimensions as industrial mechanical water meters making them completely interchangeable.

FEATURES:

1. Integral transmitter suitable for harsh environments.

2. Low maintenance no moving parts or flow obstructions translates into long-term stability.

3. Very low minimum measurable flow velocity (0.003m/s).

4. Fast response to flow rate changes.

5. Battery powered operates for 6 years.

6.Unique housing design, rated to IP68.

7. Flange/body formed as one integrated piece reduces possibility of leakage.

8. On-board self-diagnostic function and fault indicator.

APPLICATIONS:

1. Process control and instrumentation.

2. Replacing high maintenance mechanical flow meters.

3. Measure instantaneous and total flow rates in water networks.

*Notes: Battery lifetime for DN32~DN125 is 5+1 years,for DN150~DN1000 is 2+1 years.
