20+ Years Manufacturing Experience

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.

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.
