Doppler wastewater flow transducers flow sensors clamp on ultrasonic flowmeter fixed

Short Description:

DF6100-EC Wall-mounted Doppler Ultrasonic Flow Meter is designed to measure volumetric flow of liquid 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, Relays,OCT outputs.

The Doppler ultrasonic flow meter can display flow rate and flow totalizer, etc., and is configured with 4-20mA, Relays, OCT outputs.

NOTES FOR APPLICATION

1. When installing ultrasonic transducers, it need enough straight pipe;

2. When straight pipe is not enough, by setting menu SERVICE, the flowmeter will still get high accuracy, and obtain a more accurate reading.

3. The measured liquid must contain a certain amount of air bubbles or suspended solids. When the liquid contains air bubbles too much or too big, the bubbles occupy a certain volume, and then lead to larger flowmeter reading. In this case, it needs to recalibrate the flowmeter.

4. When installing clamp-on doppler ultrasonic transducers, the pipe material should have a good acoustical conductivity;

5. When the ultrasonic sensors / transducers need be installed underground, recommend the insertion type.

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, Relay and OCT outputs

Accuracy: 2.0% Calibrated span
