DUF901-EI Insertion Doppler Ultrasonic Flowmeter
DUF901-EI Insertion Doppler Ultrasonic Flowmeter can measure metal or plastic pipes with a certain amount of air
bubbles or suspended solids.
Advanced technique allows this instrument to operate with high
reliability and low maintenance. Insertion transducers permit the
instrument to be installed without interrupting system pressure or
flow.
Features:
- It is suitable for pipe sizes ranging from 65 to 4000mm
- For dirty liquids, a certain amount of air bubbles or suspended
solids shall be contained
- Excellent low flow rate measurement ability, low to 0.05m/s
- A wide range of flow measurement, high flow rate can reach 12m/s
- High-temperature transducer is suitable to liquids of -35℃ ~ 150℃
- Do not need to shut down the pipe flow when installing the
transducers
- User-friendly configuration
- 4-20mA, Relay and OCT outputs
- Accuracy: 2.0% Calibrated span
Applications:
- Raw sewage
- Activated sludge
- Ground water
- Pulp and paper slurries
- Chemical slurries
- Drainage
- Mining recirculation
