Dynameters Dmdfb Clamp-on Doppler Flow Meter

Series DMDFB Doppler ultrasonic flow meter is designed to measure volumetric flow of liquid within closed conduit, the pipe line must be filled full of liquids, there must be Ta certain amount of air bubbles or suspended solids in liquid.

The Doppler ultrasonic flow meter can display flow velocity, flow rate and flow totalizer, etc, and is configured with 4-20mA, Totalizer Pulse and Relay Alarm output.

Features:

1. The system can be field configured to pipe sizes ranging from 20 to 4000mm.

2. For dirty liquids, a certain amount of air bubbles or suspended solids contain

3. Excellent low flow rate measurement ability, low to 0.05m/s

4. A wide range of flow measurement, high flow rate can reach 12m/s

5. Automatically signal gain adjustment

6. Do not need to shut down the pipe flow when installing the transducers.

7. User-friendly configurations

8. 4-20mA, totalizer pulse and relay alarm output

9. Accuracy: 2.0% Calibrated span

Applications:

1. Raw sewage

2. Return activated sludge

3. Waste activated sludge
