DMDF-OP-A Partially Filled Pipe Flow Meters
Series DMDF-OP-A flow meter include flow calculator, transmitter, velocity transducer and level transducer.
Features:
Excellent low flow rate measurement ability, low to 0.05 m/s
Automatically signal gain adjustment
Superior measurement accuracy
Complete in specifications, and can provide a variety of applications
User-friendly configurations
4-20mA and RS485/MODBUS output, GPRS is optional
Very suitable for large pipe sewage measurement
Has national explosion proof certificate
Flow Calculator The flow calculator can set the cross-sectional area calculation of partially filled pipe or open channel, for circular pipe, it only need to input the inner diameter; for open channel, it only need to input the width; users also can input up to 20 point coordinates of channel to calculate the cross-sectional area |
|
Transmitter The transmitter and level transducer output 4-20mA analog signal of the velocity and level, which are connected to the two external 4-20mA input of flow calculator. |

Velocity Transducer
The velocity transducer includes two types: Clamp-on and Insertion, both of them are hot-tapped installation and demounted online.
When installing the insertion velocity transducer, the pipe can’t be welded directly, such as cement pipe, ductile iron or other unweldable material, please notify manufacturer for extended velocity transducers (wall thickness of pipe can be up to 110mm) shown as below. In this case, it also need to install a weldable (usually carbon steel) hoop shown as below.
Level Transducer The measurement principle of level transducer: the level transducer uses ultrasonic level meter of special small-scale and low dead zone to measure the level. When installing the level meter, user needs to fix a welding base, the height welding base is usually 80~100mm, so it can ensure a high measurement accuracy. |
