Series DMDFB 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 for Totalizer and Alarm 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 -40℃ ~ 250℃
 Do not need to shut down the pipe flow when installing the transducers
 User-friendly configuration
 4-20mA, Relay Totalizer and Relay Alarm outputs
