DUF901-EP Doppler Portable Ultrasonic Flow Meter
DUF901-EP Doppler Portable Ultrasonic Flow Meter is designed to measure volumetric flow of within closed conduit,
the pipe line must be full of liquids, and there must be a certain
amount of air bubbles or suspended solids in liquid.
The Doppler ultrasonic flow meter can display flow rate and flow
totalizer, etc., and is configured with 4-20mA, OCT outputs
Features:
- It is suitable for pipe sizes ranging from 40 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℃ ~ 200℃
- Do not need to shut down the pipe flow when installing the
transducers
- User-friendly configuration
- 4-20mA, OCT outputs
- Accuracy: 2.0% Calibrated span
- Rechargeable battery can work up to 50 hours
Applications:
- Raw sewage
- Activated sludge
- Ground water
- Pulp and paper slurries
- Chemical slurries
- Drainage
- Mining recirculation
