Doppler Insertion series ultrasonic flowmeter - DMDF-Insertion

Series DMDFC Doppler Ultrasonic Flow meters measure solids-bearing or aerated liquids in metal or plastic pipes. Proprietary circuitry allows this instrument to operate with lower concentrations of suspended solids than any competitive Doppler flow meter--expanding the instrument's range of applications and reliability. Insertion transducers permit the instrument to be installed in minutes without interrupting system pressure or flow.

Features:

1. The system can be field configured to pipe sizes ranging from 65 to 4000mm.

2. Hot-tapped installation and demounted online, do not need to shut down the pipe flow when installing the transducers.

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

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

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

6.Automatically signal gain adjustment

7.User-friendly configurations

8.4-20mA, totalizer pulse and relay alarm output

9. Accuracy: 2.0% Calibrated span

Notes:

When installing the insertion transducer, Hot-tapped installation and demounted online, do not need to shut down the pipe flow when install the transducers. while the pipe can’t be welded directly, such as cement pipe, ductile iron or other unweldable material, please notify manufacturer for extended transducers (wall thickness of pipe can be up to 110mm). In this case, it also need to install a weldable (usually carbon steel) hoop shown as below.

Solutions:

Especially suitable for large pipe sewage flow measurement, not like the electromagnetic flowmeters have the problem of electrode sensitivity decreasing. For problem of dirt stick on probe, can remove and cleaning, then reinstall and don't need to shut down the pipe flow.
